#
Abstract Test Case
See also: conctrete test case; Synonyms: logical test case; A test case without concrete input and output values for input data and predicted results. It uses logical operators because the concrete ones are not yet defined or available.
Acceptance Criteria
Those criteria that a system or component must meet in order to be accepted by the user, customer, or authorized entity.
Acceptance Test
See also: user acceptance test; synonyms: Acceptance testing; Formal testing with respect to user requirements and needs or business processes. It is performed to enable a client or authorized entity to decide, based on the acceptance criteria, whether or not to accept a system.
Accessibility
Synonyms: Accessibility; The degree to which a product or system can be used by a group of people as broad as possible in terms of their capabilities to achieve a given goal in a given context of use.
Accessibility Testing
Synonyms: Accessibility testing; testing to determine how easy it is for users with disabilities to use a component or system.
Access Security Test
See also: functionality testing; The performance of tests to determine the security (in the sense of access protection) of a software product.
Actual Result
Synonyms: tats; In test observed/generated behavior of a component or system under specified conditions.
Allocated Gold
Term that refers to the ownership of the gold. Allocated gold is physical gold that is legally the exclusive, direct property of its owner.
Alloy
Generally speaking, an alloy is a material consisting of at least two different metals. Depending on the type of alloying partners and their respective mass fraction, alloys can have very different properties, such as coloration, hardness or machinability.
Alloy: Bronze
Bronze is a metal alloy of copper and tin and is one of the very first alloys used by mankind. Since the Bronze Age, tools, weapons and jewelry are made of this material. Bronze has several advantages over its parent metals, including being harder and more resistant to cutting than copper.
Alloy: Gold
In its pure form, gold is extremely soft and easily malleable. High-quality jewelry is usually made of gold alloys with a fineness of 750 (18 carat) or above. Classic gold alloys consist of gold, silver and copper. A well-known example of this is the Krugerrand. Red gold is a mixture of fine gold, copper and only small amounts of silver. The high copper content results in a red color and a high hardness of the material. In yellow gold, silver and copper are added in approximately equal amounts. Green gold is a gold alloy of fine gold and silver, without copper additions. Depending on the mixing ratios, the shades of color can vary in intensity. Other additions, such as zinc, indium, cadmium, or gallium, can affect the melting temperature of gold. Additives such as platinum or nickel increase the hardness of the mixed alloy.
Alloy: Silver
Silver can be alloyed with many other metals besides gold. The most important silver alloys today consist of an admixture of copper. They are used, among other things, in the manufacture of coins, jewelry and cutlery. For this reason, silver with a fineness of 925 thousandths of a part of silver is also called sterling silver after the British pound sterling.
Anomaly
See also: misaction, error condition, error effect, deviation, problem; discrepancy caused by deviation from (justified) expectations of the software product. Expectations may be based on a requirements specification, design specifications, user documentation, standards, specific ideas, or other experience. Anomalies may also, but not limited to, be uncovered through reviews, testing, analysis, compilation, or use of the software product or its documentation.
Application Case
A sequence of events in a dialog between an actor and a component or system that leads to a concrete result. An actor can be a user or anything that can exchange information with the system.
Argentum
Argentum is the Latin term for silver (Ag). Nowadays, the term is hardly used among gold buyers and collectors. The name Argentum is still used as a proper name by one or the other company, which would like to adorn themselves with the word silver, without doing this too obviously. Of course, the term is also to be distinguished from the Latin word Aurum. This is the Latin term for gold. It can also be assumed that the naming of the chemical symbol Ag also originates from the letters 1 and 3 from the word. Argentum is of course also an integral part of many alloys with gold. This makes the yellow precious metal brighter. Palladium and platinum has a similar color, but also a lower value. The word is separated as follows: Ar-gen-tum.
Asset
Trading or investment property on the stock exchange.
Assets
Free funds (financial resources) that can be invested, e.g. in precious metals, shares, building savings contracts, life insurance, etc.
Audit
An independent testing of software products and processes to determine conformance to standards, guidelines, specifications, and/or procedures based on objective criteria, including documents that (1) define the design or content of the products to be created, (2) describe the process of creating the products, (3) and specify how conformance to the standards and guidelines can be demonstrated or measured.
Aurum
Aurum is the Latin name for gold (Au). Besides the fact that aurum is a synonym for gold, of course, all the content points about the precious metal are the same. The chemical element for gold is Au, which obviously consists of the first two letters of the word. Not many metals are this colorful. Only copper and some others are other precious metals with the same color intensity. The current monthly trend over the past few quarters has been that more and more "Aurum" is being stored in bonded warehouses. In bonded warehouses, precious metals are stored tax-free in other countries without having to cross borders. It is stored directly in the corresponding country. Gold and silver are the most popular precious metals, which stimulate stock lists especially in Switzerland or Hong Kong.
Availability
Der Grad, zu dem eine Komponente oder ein System im operativen Betrieb bzw. für die Nutzung zur Verfügung steht.
Base Price
The strike price is the price at which one can sell an underlying asset on the record date (expiration date). Strike prices exist primarily for options. They describe the value that an investor can redeem with the option. This value can be deposited in various forms. Typically, shares are the so-called underlying. However, commodities such as gold but also grain or pig halves, etc. are also conceivable. Known are also options with the underlying interest, currencies or even options. With the option business the owner of the option does not have to buy the basic value at the current price, but can redeem its option against it. Most options are limited in time and can also expire afterwards and not be redeemed.
Bearer Bond
A bearer bond is a subtype of bond in which the owner of the certificate is not mentioned by name on the certificate. Bearer bonds have a high degree of fungibility due to their informal transferability, so that they can also be traded as securities on a stock exchange.
Bearish
See bear market
Bear Market
Sustained downward movement of prices and the time during which prices remain low. Also referred to as a bear market. The opposite is a bull market.
Behavior
The response of a component or system to a set of inputs given certain preconditions.
Ben Bernanke
U.S. economist who succeeded Alan Greenspan as Chairman of the Federal Reserve from February 1, 2006, to early 2014.
Benchmark
Reference value against which one can measure one's own investment or the performance of funds. Important indices such as the DAX often serve as benchmarks.
Beta Test
Synonyms: Field test; testing or trial operation of a software product by representative customers/users in the customer's/user's deployment environment to determine whether a component or system meets customer needs and fits business processes. Beta testing is a type of external acceptance test used to obtain feedback from the market before final release.
Black Box Test Design Process
Synonyms: Black-box procedure, specification-based procedure, specification-oriented test design procedure, specification-based test design procedure, specification-based procedure, black-box test design procedure; A procedure for deriving and selecting test cases. It is based on an analysis of the functional or non-functional requirements (specifications) of a component or system without considering its internal structure.
Blister Card
Anyone who purchases precious metals such as coins or bars often expects the item to be secure on the one hand and attractively packaged on the other. Here, the blister card has meanwhile established itself as packaging for precious metals of all kinds.
Blister Card: Optical Stimuli
However, the fact that the packaging of a precious metal is not only about the robustness and security, but also the external appearance, is an important aspect. With the blister card, you acquire a visually very appealing packaging that shows off the precious metal well in many areas of application. Whether in your own display case or as a gift for others: The blister card protects professionally and in addition lets the content be shown off perfectly.
Blister Card: Protection against Counterfeiting
In addition to the external protective function of blister cards, you also acquire packaging that protects you against counterfeiting. Thus, all blister cards used by Kettner Edelmetalle are provided with an individual serial number which, in combination with a certificate, makes the precious metal almost forgery-proof.
Blister Card: Robust and Practical
The air- and waterproof welded blister card optimally protects the precious metal and thus preserves the original condition over a long period of time. This means you can transfer the item to your collection in its original packaging and risk no scratches, fingerprints or other damage by removing it from the packaging. A major advantage that results from this: The precious metal retains its condition and allows you to make a high profit when you resell it. Coins like the Maple Leaf Gold do not usually reach you in blister cards. We ship coins in coin capsules.
Blister Card: Serial Number on the Bar
Rand Refinery demonstrates that existing rules of blister cards can also be broken. Until now, it was typical to print the individual serial number of an ingot on the paper insert between the plastic layers. Anyone who removed the blister could not accurately identify the bar. Rand Refinery now began stamping the serial numbers directly on the bar. Before that, an "RR" appears for the name of the manufacturer. With this bar, the African producer may even manage to diminish the importance of coins like the Gold Somalia Elephant, as they even have a motif on the back. The most famous gold bars in the blister are the Degussa gold bars, which we can also highly recommend to you!
Blister Card: Sturdy Standard
A blister card is a packaging for precious metals of all kinds. It is made of transparent plastic, which allows you to see the contents on the front and back, and yet is a sturdy packaging. Due to the standardized size of the card, various silver and gold bars can be presented decoratively.
Bond, Debenture
Security, bond or debenture with a fixed interest rate. This often refers to government long-term treasury bonds.
Bonded Warehouse
Bonded warehouses have existed in Switzerland since the 1970s and in Hong Kong for some time. Originally, they were intended as transit warehouses to facilitate trade. If goods were not imported into Switzerland, neither import duties nor value added tax had to be paid. Now that banking secrecy has been abolished in Switzerland and tax evaders are extradited to their home country, these warehouses offer the opportunity to deposit at least precious metals and other movable assets. In addition to precious metals, it is not uncommon for works of art and countless liters of wine to be stored in the inconspicuous high-security facilities. Discretion is another criterion for the increasing demand. However, anonymity is the main selling point, and it is precisely this anonymity that encourages abuse. If, for example, gold is purchased in this fiscal no-man's land and stored there, neither value-added tax nor import duties are incurred. As long as this gold does not leave the free warehouse, no customs duties are incurred for delivery. The operators, mostly forwarding companies, have to declare what is in their warehouses, but not who the owner is. Random checks are made by the customs authorities, but only with regard to whether someone can basically afford what they have stored.
Brilliants
Brilliant is a synonym for a diamond with the so-called brilliant cut. This cut was developed around 1910 and is characterized by its particular fineness and brilliance. The term "brilliant" comes from the French adjective "brillamment" and means "shining" or "radiant". These words also describe the special feature of the brilliant very well: It is characterized by the fact that it refracts the light in a very special way and thus great light, brilliance and color games appear. That is why it is often bought for jewelry in combination of gold and silver. Characteristics of the brilliant cut are that the brilliant consists of at least 56 facets plus table (the wider facet at the top). These break down as follows: At least 32 facets plus table in the upper part and at least 24 facet including culet (the pointed end) in the lower part. Examples of brilliant-cut diamonds include the Tolkowsky diamond, which is particularly high-yielding in terms of light. Also, the Ideal diamond, which became famous in 1926. One of the newest brilliant is the Scandinavian Standard Brilliant from 1968.
Broadband Delphi
An expert-based test estimation procedure, with the goal of arriving at the most accurate estimate possible by involving team members.
Broken Gold
Again and again you come across offers that they want to buy broken gold from you. But what is that? So-called broken gold is usually jewelry that is made of gold, but is broken or broken and where it would no longer make purely economic sense to repair it. However, the category of broken gold also includes gold remnants that are left over during the jewelry manufacturing process.
Broken Gold: What is its Value?
The owners of broken gold often underestimate the value of their broken gold. In most cases, the broken jewelry only has an ideal value for them, since it can no longer be worn. However, it should not be forgotten that broken gold can be turned into hard cash: The higher the fine gold content of the jewelry, the more the broken gold is worth.
Broken Gold: What to look for in the Sale?
When selling broken gold, you should first and foremost pay attention to the gold price trend. Ideally, you sell your broken gold when the gold price is very high, because at this time you can get a great return.
Bullion Banks
Investment banks that are members of the LBMA and act like wholesalers by trading large quantities of gold.
Bullish
See bull market
Bull Market
Sustained rise in prices and the period during which prices remain high. Also called a bull market or bull market. The opposite is a bear market.

Carat
Carat, also called metric carat, is the measurement of the size of a gemstone. One metric carat is 0.2 grams. Carat is a legally defined unit, which is indicated in Germany with the sign "Kt" (Karat). It was introduced in1875 according to the Metre Convention. Carat as a unit of weight, however, must not be confused with carat as a measurement for the purity of gold. The term carat is derived from the Latin word "carratus", whose origin in turn lies in Greek as a term for a legume. This fruit of the carob tree has the shape of a croissant and its seeds were often used as weight stones in the past, as they were said to always have the same size and therefore the same weight. This weight was 0.2 grams.
Carat Prices
Depending on the gemstone, the price per carat can vary greatly as it is influenced by many factors. Examples include color, clarity, cut, place of origin, size, supply chain, fashion, shape, and treatment.

Chart
Graphical representation of the development of a price, e.g. for the gold price, securities, etc.
Chemical Element Gold
The chemical element of gold is Au. The word gold comes from the Indo-Germanic word "ghel", which means "shiny" or "yellow". However, it is also a chemical element that has the element symbol Au. This abbreviation, in turn, comes from the Latin word "aurum," which means "the gold." In the periodic table Au has the atomic number 79. The chemical element gold (Au) is a transition metal, which stands in the periodic table in the first subgroup, which is also called copper group or coinage metals. Gold also belongs to the group of precious metals and is one of the few metals, like copper, that has a color.
Checklist-Based Review

Checklist-Based Testing
An experience-based test design process in which the experienced tester uses a list of checkpoints that must be observed, reviewed, or remembered, or a set of rules or criteria against which a product must be verified.
Chemical Element Silver
The chemical element of silver is Ag. Silver is a precious metal. It also has the atomic number 47 in the periodic table and belongs to the transition metals. The word origin of silver is not yet completely clear, but the chemical element symbol Ag is derived from the Latin word "argentum". Silver is relatively soft and easily malleable. It is the heavy metal that has the highest electrical conductivity of all elements and the highest thermal conductivity of all metals. Its melting temperature is 961 degrees and its boiling temperature is 2212 degrees Celsius. The appearance of silver can be described as white shiny and metallic.
Chemical Element Silver: History
Silver has been processed by people since about the 5th millennium BC. Especially the Assyrians, Greeks, Teutons or Romans are known to have used it and at times the value of silver was even higher than that of gold. In the Middle Ages, Schwaz was the largest producer of silver - up to 80% of the silver produced at that time came from its tunnels. After 1870, however, almost only gold was used as a currency metal, which is why silver increasingly lost its economic significance and is now mainly used as jewelry.

Degree of Preservation
The grade is the classification of the quality and shape of a coin. It indicates how much a coin is worn by daily handling and circulation. Coin collectors are particularly interested in coins with a high degree of preservation, which means that they show relatively few signs of use. Roughly, it can be said that the higher the degree of preservation, the fewer circulation marks a coin shows. The lower the degree of preservation, the more defects, or wear marks it shows. Thus, the conservation value strongly influences the collector value of a coin. There is a certain scale with defined gradations, through which the coins are characterized either with words or with abbreviations. But not only the wear, but also other influences determine the collector value of a coin. In special cases, for example, damage typical of the preservation can increase the grade. For some coins, the conservation value can also be increased by restoration measures or cleaning.
Dental Gold
The fact that dentures are very expensive is no longer a secret. If you want to have bridges, crowns or even felling replaced, you should definitely make sure to take the old dentures back with you. This is possible without any problems and also makes sense, because: Dentures with gold components are cash money. If there are bridges or crowns with gold components in old precipitations, it is worthwhile to calculate the current dental gold price - this can be done quickly on the Internet. Gold can be found in old fillings, bridges and crowns. In 3 simple steps you will get an absolutely fair price for your dental gold:
- Separate gold and tooth: Each tooth has its own weight. Buyers often use this as an excuse to drive down the price of gold. If you are able to separate the gold from the tooth by a dentist or yourself, you will find out the real weight. Tip: Some dentists also buy gold. Since he is only a middleman, you usually get less money.
- Protect the quality of the gold: Since gold is almost as soft as butter, dental gold is never 100% gold. It is present in a so-called alloy. With pure gold we speak of 999/1000 or 999 gold. So it is almost 100% pure gold. Dental gold is more like 58.5% gold content (585 gold), which in other words is also 14 carats. With the help of the gold content, we can calculate the real gold value right away!
- Weighing gold: When it comes to valuable gold, we better play it safe! Always weigh your dental gold with an accurate digital scale. After that, you can calculate the value of your dental gold:
- Use the current gold price in euros. The gold price is given in 1 ounce (31.103 grams).
- Therefore, divide the gold price by 31.103. Now you have the current gold price per gram.
- Multiply this price by the weight of the gold in grams.
- The result multiplied by the gold content divided by 100 (weight * 58.5 / 100) calculates the value of your dental gold.
Derivative
Financial instrument or mutual contract that derives its value from the current fair value of a market-related reference variable, e.g. futures or options.
Dignified
In mineralogy, the occurrence of pure chemical elements in nature is called native. Precious metals such as silver, copper, gold, and palladium are especially native. But also non-metals can occur in nature in their elemental form. Examples are carbon (graphite or diamond), sulfur or noble gases. However, these other substances are not usually called native, this term is usually used only for the precious metals. In total, there are about 20 elements in the periodic table in the native state.

Federal Reserve Bank, Fed
Central banking system of the United States of America. Its main task is to create price stability and thereby achieve low unemployment, a long-term balance of payments and sustainable economic growth.
Fiat Currency
Currency without intrinsic value that is considered a medium of exchange. The opposite is commodity money, which has intrinsic value in addition to exchange value, such as gold and silver. The term "fiat" comes from Latin: The verb "fieri" means something like "to happen" or "to come into being." "Fiat" therefore describes something transitory.
Findings
A result of an evaluation that describes an important failure effect, problem, or opportunity.
Fineness
The fineness of a precious metal expresses the percentage of a precious metal in a coin or bar. The fineness is expressed in parts per thousand. This means the specification in 1000 parts of the total weight. Other measures such as lot or carat were in use, especially before 1888. One way to indicate the fineness is to stamp it, but this is not obligatory.
Fineness especially for Precious Metals
For most precious metals, the highest fineness is 999.9 parts per thousand. Purity grades higher than this can only be produced at great expense and are not available in normal trade, as they are usually only used for physical or chemical purposes. For coins, the fineness is also referred to as fineness, fine or grain.
Fineness for Jewelry
In jewelry making, goldsmiths usually use finenesses between 585 and 999; the higher the fineness, the more expensive and valuable the piece of jewelry, of course. For jewelry from industrial production, the fineness is usually between 333 and 750.
Fineness (Net Weight)
The fineness or net weight of a coin or ingot is the pure weight component of the precious metal without alloys or inclusions. Inclusions are often used to change the color or hardness of a metal. However, the higher the fineness, the more valuable it is. The total mass is called the rough weight, gross weight, or shot, and the ratio of fine to rough weight is the fineness. For example, if a piece of jewelry weighs 3 grams and has a purity of 18 carats (650/1000), it is 650 parts pure gold, or pure silver, and 350 parts other metals. Now, to find out the fineness, you have to divide the precious metal content by the total sum of all metals and multiply this value by the total weight. Here would be the following calculation: 650/1000 = 0,65; 0,65 x 3 = 1,95g pure precious metal (silver/gold)
Fineness Stamp
In Germany, anyone can stamp their gold and silver jewelry with a fineness mark. However, the law does not make this information mandatory. However, if jewelry made of the aforementioned precious metals is stamped, it must absolutely comply with the legal requirements. Accordingly, only gold and silver material may be marked with the sign of the sun or the crescent moon and the sign of the company. Gold should be marked with a fineness of at least 585 parts per thousand and silver with a fineness of at least 800 thousandths.
Fine Ounce
Mass measure for precious metals. Refers only to the precious metal content. A troy ounce (abbreviation "oz") is exactly 31.1034768gr heavy. This weight is also called Troy ounce in Anglo-American. The standard gold bars of the LBMA have a weight of 400 troy ounces. From the total weight of the coin here all foreign substances and alloys are deducted, the result thus indicates the pure precious metal value. Especially for bullion coins, the value of the troy ounce is used, e.g. for gold, silver, palladium or platinum. But also the gold price, for example, is given in troy ounces (short: ounces). If it stands, for example, at 967.03 â'¬, it means the price per troy ounce of gold. Normally, all coins are quoted in this unit, the only exception being the gold mark, which is described as weighing 12 grams. In the case of precious metal bars, on the other hand, the weight is predominantly given in grams, or kilograms, since large quantities of precious metal are involved here.
Fine Ounce: Origin of the Term
The word ounce comes from the Latin term “uncia,†which means “one twelfth.â In the Anglo-American system of measurement, the troy ounce is known as the troy ounce, named after the French city of Troyes, which was an important trading center in the Middle Ages. 1 troy ounce (oz. tr.) = 1/12 troy-pound (lb.tr.) = 20 pennyweight (dwt.) = 480 grain (gr.) = 31.1034768 gram (g)
Fine Ounce: Risk of Confusion with other Ounces
The troy ounce can easily be confused with other units of measurement called ounce. The following units of measure exist:
- Common ounce: Often used instead of grams for food in English-speaking countries. 1 common ounce (oz) = 28.349 grams.
- Pharmacist ounce: Formerly used for weighing medicines and chemical substances. 1 apothecary ounce (oz. ap.) = approx. 31.1 grams
- Fluid ounce: Unit of measurement for measuring the volume of liquids in the English-speaking world. 1 fluid ounce = 29.5735 cm³
- Metric ounce: Still widely used in the Netherlands and Indonesia. 1 Metric Ounce = 100 Grams

Gold
Gold is a shiny yellowish precious metal (chemical element, atomic number 79, mass number 197, symbol: Au/ Latin: Aurum). It has excellent polishing properties and is extremely malleable. Around 85 percent of the gold mined is used to make jewelry - making jewelry processing the most important use. In addition, gold is also ideal for investment purposes: because it is inflation-proof, it is also bought by central banks as protection against a currency crisis.
Gold Alloy
In gold alloys, gold is combined or fused with various other metals. The most common are gold alloys with silver or copper. But there are also compounds with platinum, palladium, nickel, cadmium, zinc, iron, tungsten and tantalum. The color of gold is determined by the alloying additions. However, the color does not directly indicate the composition. With the help of treatment with acids, as well as polishing, the usual gold color can be restored. Measured per 1000 parts of alloy, there are.
Gold Art
Gold art is the artistic creation or decoration of objects made of gold. These can be large pieces such as gold chalices, crowns or candlesticks as well as small household items such as wedding rings, earrings or pendants. Often the term is used for gold jewelry.
Gold Art: Craft Techniques
The basic shape of a piece of gold jewelry is often created by casting. This is then further processed by filing, sawing, drawing, driving, hammering, rolling and similar techniques to finally be brought to the desired appearance by grinding, polishing or matting. In some cases, an engraving is applied at the end. By combining different colored gold alloys (yellow gold, white gold, red gold) as well as the combination of gold with precious stones or other precious metals, varied effects are achieved beyond the pure gold processing.
Gold Art: Examples of Works of Art made of Gold
In former times, it was customary to produce golden book covers as imperial gifts, which were supposed to correspond to the value of the contained handwritten books with artful depictions. For example, the Gospel book covers of the Codex aureus of St. Emmeram have been preserved. The Essen Golden Madonna from the turn of the millennium is an example of the combination of sculpture with gold craftsmanship, in that a wooden statue is covered with sheet gold. While ancient art made of gold often had to do with cultic objects, for several centuries secular pieces have increasingly been crafted of gold, once used by the nobility, today by the moneyed aristocracy, to bring a certain splendor into households.
Gold Art: Gold Artists and their Training
The artistic aspect can refer to both the craftsmanship of a golden workpiece and the artistic design. Depending on the golden works of art are designed by craftsmen or artists. Accordingly, various training courses lead to the gold artist - the traditional goldsmith apprenticeship as well as studies at a technical school for precious metal trades or studies at an art academy. Of course, the design and manufacture or decoration of objects made of gold can also be done by different people.

Gold Deposit
Gold deposit is given in a place where gold was found more than easily. Gold has been mined for as long as there have been advanced human civilizations. Estimates suggest that about 160,000 tons of the coveted precious metal have been mined throughout history. This amount is just enough to fill two Olympic swimming pools. For a long time, gold was laboriously hammered out of the earth, and the miners' yield was correspondingly small. After the Middle Ages, when the easily accessible gold deposits in Europe were almost exhausted, new mining areas had to be opened up.
Gold Deposits: The Discovery of America
With the discovery of America, the gold-rich areas of the Klondike and California became available to the European soldiers of fortune. And rich deposits in South Africa, Canada or Russia were also eventually made accessible. But it wasn't until the industrial revolution and the associated technological advancements that the earth's gold deposits were really exploited on a large scale. It is thus assumed that today more gold is mined in two years than in the period from the end of the migration of peoples to the beginning of modern times. Like any raw material, however, gold is not inexhaustible. Similar to crude oil or natural gas, economic mining will therefore no longer be worthwhile in most regions of the world within the next 50 to 100 years.
Gold Deposits: Many Deposits already depleted
In many countries today it is already necessary to search a ton of rock for a gram of gold. Therefore, attempts have been made to extract gold from seawater. However, this failed because of the technical and financial difficulties. Larger gold deposits can still be found in Australia, South Africa and in the successor states of the former Soviet Union. Scientists assume that more than one third of the remaining deposits are located in these three countries.
Gold-Investor-Index
The Gold Investor Index is calculated from data from BullionVault, the world's largest online exchange for physical gold and silver, and measures the ratio of gold buyers to sellers. This reflects the sentiment among private investors towards gold and ultimately the economic situation.
Gold Leaf
Gold leaf is a foil made of pure or very high quality gold. Gold leaf is mainly used for finishing non-metallic objects. The gold is pressed by many pressing processes to such a small thickness that it is relatively cheap and yet the optical effect of gold is visible. The gold leaf shines golden yellow like yellow gold.
Gold Leaf Production
The production of gold leaf is extremely complex and is becoming more and more perfect. Even in Roman times, gold leaf was extremely soft, with a thickness of three thousandths of a millimeter. Today, thicknesses of approximately one ten-thousandth of a millimeter are achieved. Gold is melted and combined with silver, platinum or copper, depending on the desired color. It is finally cast into ingots about 2 millimeters thick, which are then rolled very flat. Only now are the flat sheets of gold leaf separated with parchment paper carefully worked with spring hammers and pressed further and further.
Gold Leaf Use
>Gold leaf is used in various fields. A classic area is architecture. An extreme example is, for example, the Venetian Macau Hotel, in which over 3,000,000 gold leaf sheets of approx. 80x80mm each were used. Of course, picture frames, statues, etc. are also classic objects of use. More and more, gold leaf is also used to refine luxury food. Often, edible gold leaf is a reason for restaurant owners to significantly increase the price of a dish. But caution should be exercised, because 1 gram of gold leaf, which can be purchased for about 80 to 100 euros, is enough for 300 to 400 applications. This corresponds to about 30 cents per dish.
Gold Market
The global professional gold market is divided into two sectors: 1. derivatives (gold futures and options) and 2. physical, real gold. While the largest markets for gold futures and options are located in New York and Tokyo, physical gold is traded in London, Zurich and Hong Kong.
Gold Medals
The gold medal originally refers to an object minted from the precious metal gold solid for commemorative purposes. It is presented as a piece of jewelry on a special occasion. The gold medals are rarely produced, unlike the medals of bronze or silver. Solid gold is generally used here. Great personalities from history often initiated the minting of these special medals to very special events to record them for posterity. For example, they were minted for coronations at court or births. Many sporting events such as competitions, especially the Olympic Games, were and still are occasions for honoring the victorious athletes with a medal made of this precious metal. Also an extraordinary merit, for example, in society, science and politics is often honored with a gold medal. For a long time, it is thus ensured that even in the distant future many generations will remember these special events.
Gold Medals: Alloy
However, different alloys are also used in the production of the gold medal. This means that not every medal is necessarily made of pure or real gold. These special alloys should imitate the gold luster as well as possible. Brass or tombac, among others, served this purpose. Furthermore, a medal can also be covered with a thin layer of gold, in this case is called gilding. In this way, it can be produced more cheaply, and its external appearance resembles that of real gold. Even today, this manufacturing process is still used. At the Olympic Games, for example, a gold medal is first made of silver and then covered with a layer of solid gold.
Gold Mining
Gold is dissolved out of the surrounding rock (gold vein) in mines, sieved out of the sand or washed out of boulder deposits. Mountain gold is often encased in quartz. Soap gold results from rock weathering, which releases the gold and carries it away via rivers. Gold dust, flakes, or grains are obtained in this manner. Wash gold is extracted from rock sediments by repeated washing and sieving in bowls, pans or long troughs. The most important mining countries include South Africa, Canada, USA, Australia, China and Russia.
Gold Panning
Gold panning, compared to industrial mining in general, refers to the traditional exploitation of gold deposits by a prospector. Different methods are used here. The search for gold in the industrial sense is basically undertaken for economic reasons, but now also serves as a hobby or leisure activity.
Gold Panning: Gold Concentration at the Bottom of the Pan
This process is repeated several times. This results in a concentration of the remaining material on the bottom of the container. This remaining material then usually consists of heavy pieces such as, ideally, gold. Most deposits are mostly exhausted, so panning gold in this way is no longer profitable. Occasionally, fine gold dust can still be found. However, this may indicate further deposits of gold in corresponding rocks in the further course of the river. For the hobby gold panner this can still be an incentive.
Gold Panning: One of the oldest Gold Mning Methods
Traditionally, gold is panned in a dedicated trough, also known as a gold pan. This procedure is one of the oldest ways of extracting gold from non-solid sediments in rivers or streams. Large mining companies still use this method today to find gold deposits. A gold prospector without adequate financial means usually has only this option for practical extraction of gold.
Gold Panning: Procedure
The sand and rock material from flowing water is fed as a water mixture into a round container. By rotating and occasionally shaking the trough, the constituents are sorted out according to their size. The large particles remain at the bottom of the container, and the small pieces spread out along the rim. Then the vessel is tilted slightly, and a little of the water-sand mixture flows out over the rim.
Gold Quantity
The amount of gold on earth is the explored amount of gold on the whole world (mostly in tons). The amount of gold available on Earth is believed to be severely limited. The amount of gold is synonymous with the terms gold stocks and gold reserves. In the entire history of mankind, it is estimated that 170,000 tons of gold have been mined. Cast into a cube, you would get a cube with an edge length of 20.6 meters. Converted to the world's population, each citizen of the earth would have an average of 24.3 grams of gold at his or her disposal.
Gold Quantity: Mining and Consumption
For a long time, South Africa was the largest gold producer in terms of volume. In 2008, however, South Africa was replaced by the People's Republic of China. In China, 355 tons of gold were mined in 2011 alone. In second place is Australia with a production volume of 270 tons. Australia is home to the largest unmined gold reserves with an estimated 7,400 tons. Globally, 51,000 tons of recoverable gold are believed to remain. At current mining rates, the known reserves will last for about 20 years. But for years now, consumption has far exceeded extraction. The difference is made up partly by sales of the central banks' gold reserves, and partly by recycling and melting down jewelry and scrap gold.
Gold Quantity: What is the Gold used for?
By far the largest share was processed into jewelry. At over 79,000 tons, just over half of the total amount of gold available is consumed for jewelry of all kinds. In second place in terms of volume, with 28,600 tons, are the gold reserves of the world's central banks and monetary institutions. The largest foreign reserves invested in gold are held by the United States with 8,133 tons, followed by Germany (3,395t), the IMF (2814t), Italy (2,451) and France (2435t). Just under 25,000 or 16% is privately owned in the form of bars and gold coins, 18,000 tons or 12%, was processed into art objects. A small part with about 150 tons per year is used in electronic devices.
Gold Rush
A gold rush is the time when people sought wealth and financial independence to an excessive degree by mining gold.
Gold Rush: Gold and the Peoples
Gold, how does this name sound in the ears of man. Egyptians, Mayans, Romans and the Spanish conquerors of South America were addicted to the yellowish precious metal. They sacrificed it to their gods, gilded religious sites with it, and used it to pay for grain or their armies. Gold has a high specific gravity and can withstand almost any chemical attack. But with few exceptions, aurum, as it is called in Latin, was for centuries a metal not particularly useful in practical life. Its melting point is low and it cannot be forged into weapons or tools. But its unique appearance fascinated people.
Gold Rush: Wars for Gold
Wars were fought and countries conquered for gold. Even today, romantics dream of the legendary Eldorado, the gold country in the heart of South America that promises unlimited wealth. Especially the American continent is always associated with gold. Who does not know the gold rush, which in the 19th century brought hundreds of thousands of people to California and Alaska to seek their fortune. San Francisco is probably the most famous city that owes its existence to the search for gold. But for many, unfortunately, the longing for wealth was in vain. In the California desert or in the icy cold of Alaska, they sifted through countless tons of sand, stones and mud. They braved raids, famine, and cutthroats who robbed them of their hard-earned gold. And in the end, most of the soldiers of fortune could just about afford to go home. But with some Nebu, the Egyptian goddess of gold, had leniency. She poured out her horn of plenty on them and gave them and their descendants almost unlimited wealth.
Gold Standard
Monetary system in which the currency consists of gold coins or at least banknotes that can be exchanged for gold. The gold standard was prevalent between 1870 and World War I. In the U.S., President Nixon removed the dollar's gold peg in 1971.
Gold Usage
Gold has been used by people for thousands of years. Whether for ritual objects, jewelry or for gold coins and thus as a means of payment - gold has a very long tradition. Meanwhile, it can even be used as a food additive. These examples show not only the long tradition, but also the enormous value of gold, which underlies it for several millennia.
Gold Weight
The specific gravity of gold is 19.32 g/cm³, the atomic weight 196.967u. The melting point is 1063 degrees Celsius, and the boiling point is 2960 degrees Celsius. The gold weight is internationally indicated in "troy ounces". One troy ounce of gold is equal to 31.1035 grams. A troy ounce is said to contain a maximum of one hundred percent gold. The "purity" is also called "fineness". The fineness indicates the proportion of pure gold in relation to the total weight. Another common term for it is the indication in carats. The indication in carats for gold is not to be equated with the carat designation of precious stones, where carats are subject to a weight indication (1 carat = 0.2 grams).
Good Delivery Bars
In the professional gold and silver market, only good-delivery bars are traded. These are cast exclusively by selected, recognized metal refiners, transported by recognized transport companies and stored in certified vaults. Such gold bars always have a purity of at least 99.5% gold and weigh around 400 troy ounces (12.4 kg). Silver bars have a purity of at least 99.9% and weigh around 1,000 troy ounces (31.1 Kg).
Government Bonds
Exchange-traded debt security issued by the government with a term of usually 10 - 30 years.
Gross Weight
Gross weight is the total weight of a composite of a substance and other materials. In the case of precious metals, of course, gross weight refers exclusively to the combination of a metal with one or more other materials. A typical example is the weight of a gold tooth sent in. This consists of the combination of gold and tooth. While the Pure Gold Weight would be the net weight, the Gross Weight is the total weight if the entire tooth were weighed.

Integration Test
See also: component integration test, system integration test; testing with the aim of uncovering error states in the interfaces and interaction between integrated components. In software development, the term integration test refers to a coordinated series of individual tests that are used to test various interdependent components of a complex system in interaction with each other. Ideally, the components to be tested for the first time in a common context have successfully passed respective module tests, subtests or component tests and are functional in isolation without errors.
Integrity Chain
The chain of integrity is an important component in the professional gold and silver market, which guarantees the quality of the "good delivery" bars. They may only be handled by certain selected refiners, transporters and vault operators. Purity, size, shape, appearance and marking are standardized for these bars. These standards (and therefore value) can only be guaranteed as long as the precious metal does not leave the integrity chain.

A development model in which the project is divided into a larger number of iterations. An iteration is a complete development cycle that results in a release (internal or external) of an executable product. This product is a subset of the final product to be developed. The development progresses from iteration to iteration towards the final product.
Karat
Size indication of physics. Mostly used as a designation for the purity grade of gold. The higher the karat number, the higher the gold content. 24-karat gold is considered pure gold, which has the designation "gold 999". The fineness of silver is not expressed in carats.
Karat: Mass of Gold in Relation to total Mass
What is meant here is the proportion of mass in relation to the total mass of the alloy. Gold has a high molecular mass, unlike other metals. For example, the coinage “333†means that the gold has a proportion of 333 and all other additional metals have a proportion of 667 parts. These additional metals can represent silver, zinc, copper, or tin, but other non-precious metals are also used here. The proportions result from the atomic ratio to each other.
Karat: Other Gold Content Classifications
There are other gold content classifications here, but they are no longer all in use or are no longer used in Germany. This designation is abbreviated as “ktâ€. For coinage on watches, the abbreviation "C" is also often used. The silver fineness, by the way, is not given in this unit. Here, a scale is used which consists of 16 parts and is called "solderiness".
Key Interest Rate

Measurement
The process of assigning a number or category to an entity to describe an attribute of that entity.
Melting Point
The melting point, also melting temperature, is the temperature at which an element changes its state of aggregation from solid to liquid. Especially for pure chemical elements, the melting point is usually known. The melting temperature depends on the substance and, in contrast to the boiling temperature, only slightly on the pressure. With the help of a thermometer the temperature can be determined approximately, however, there are different methods for the exact determination. In the meantime, however, automatic melting point measuring devices are used in laboratories, which display the exact result within a very short time.
Melting Point: Importance for Goldsmiths
In jewelry making, a precise knowledge of the melting points of the individual precious metals is enormously important, as they influence important decisions. These can be which soldering method is used, whether the gemstones need to be set out of the material during soldering, and many more. Special attention should be paid to alloys with extremely large or extremely small melting intervals, since large melting ranges greatly narrow the choice of solders, and small melting ranges require meticulous control that is nearly impossible to achieve by hand.
Melting Point: Other
Substances that are naturally solid under normal temperature conditions, such as iron or calcium, logically also have a significantly higher melting temperature than water. And conversely, for normally gaseous substances such as oxygen or helium, it is well below zero. The noble metals are a group of substances in the periodic table with metallic properties. In addition, they are characterized by the fact that they hardly react with water and are thus resistant to corrosion. These precious metals include the sought-after substances gold, silver and platinum, but also osmium, iridium, palladium, rhodium and ruthenium. Precious metals have high melting temperatures, which are usually only reached with a strong fire or in blast furnaces. Melting precious metals is a practical method of casting them into ingot form, making them countable. On the other hand, jewelry melted in house fires is a real nuisance. The approximate melting points of precious metals are: silver: 961 ° C; gold: 1063 ° C; platinum: 1768 ° C; palladium: 1555 ° C; rhodium: 1964 ° C; ruthenium: 2334 ° C; iridium: 2466 ° C; osmium: 5000 ° C.

Mint Assignment in Germany
Since 1871, individual coins can be assigned to their mint by a capital letter on the reverse of the coin. In Germany, there were a total of 34 mints of which five are still active today. Thus, the letter "A" indicates the mint of Berlin, "D" - Munich, "F" - Stuttgart, "G" - Karlsruhe and "J" - Hamburg. Hamburg mint has a centuries-long history, where the first coin was minted in 834. Hamburg is known for the high quality of special coins and individual medals. Karlsruhe and Stuttgart have been functioning together as Germany's largest mint since 1998. Munich has stood for high-quality circulation coins as well as collector coins for 850 years, and Berlin has been considered outstanding in the production of coins and medals since 1280. European coins use both letters and symbols as mint marks. While the Italian mint in Rome is distinguished by the letter "R," the Dutch mint in Utrecht strikes a staff of Mercury on its products, and the Spanish mint in Madrid uses an "M" with a crown. When the German Empire was founded in 1871, the right to mint coins passed from the individual states to the Empire. By resolution of the Bundesrat on December 7, 1871, capital letters were introduced as the mint mark. The order of distribution was based on the order in which the federal states were ranked in Article 6 of the Imperial Constitution. There was one peculiarity, the letter I was omitted because too great a risk of confusion with the letter J was suspected. Since only a small part of the former mints is still active, some letters are missing nowadays. Frankfurt am Main, for example, had the letter C, Dresden E and Darmstadt H.
Mints
Minting offices or mints are traditionally responsible for the production of coinage, the designation as "office" they owe to their historically sovereign function in monitoring the quality of coins. In the Middle Ages, the position of Master of the Mint was created, an office that was passed down through generations in families. Today, the ECB controls European coin production. In addition to the normal coins used in everyday life, the institutions also issue special mintings of gold coins, silver coins and platinum coins.
Mints: Gold and Silver Coins
The gold euro is issued by the national mints of the individual euro states; in Germany, these are the mints in Berlin, Munich, Stuttgart, Hamburg and Karlsruhe. It has been available since 2002 with a face value of 100 euros as a 1/2 oz coin and 200 euros as a 1 oz coin. This coin was minted only in 2002. The motifs are almost always Unesco World Heritage Sites, such as Quedlinburg in 2003, Bamberg in 2004, in 2005 they chose the World Cup as a motif, followed again from 2006 German cities such as Weimar, Lübeck, Goslar and others. In silver there is the 10 Euro commemorative coin, in addition, a very prominent European silver coin is the Vienna Philharmonic, which of course is also available in gold. In Germany (and only here) the 10 Euro silver commemorative coins are an official means of payment. While the gold coins are made of fine gold, the silver content of the commemorative coins until 2010 in mirror finish was 925/1000 parts silver (sterling silver), since 2011 only 625/1000 parts, because the price of silver had risen. We have prepared for you an overview of various coins from different countries.
Mints in Germany
Mints are industrial facilities that have been designing, producing and delivering bullion and commemorative coins since the 19th century. These are state institutions that are subordinate to the government's finance department and also produce precious metal coins made of gold, silver, platinum and palladium as collector's items and valuable investments. The world’s first mint existed in Lydia, Asia Minor, in the 7th century BC. The first state mint still exists today and is located in England with the British Royal Mint. "Mint" or "mint" is often used as a synonym for the word "mint." Note the difference with mints. In Germany, only 5 of the original 34 mints for coins are still active. All mints are also involved in the production of the gold euro.
Mints in Germany: Designs
The gold coins, which are produced in Germany, are often simple in design and express the historical and cultural self-image of our country. The coins are dedicated to personalities or significant themes from politics, science, culture, architecture and sports. The motifs are intended to be a reflection of society and also to stimulate discussion and evoke memories. Approximately 10 collector coins are issued each year and the motifs are decided by the Federal Cabinet
Mints in Germany: Tasks
In addition to the production of the eight German euro circulation coins with the denominations 1 cent, 5 cent, 10 cent, 20 cent, 50 cent, 1 euro and 2 euro, which have been introduced since 2002, the state mints also produce the well-known commemorative coins. The minting houses receive the order for production from the Federal Ministry of Finance. The fact that in Germany the production is spread over several places is a peculiarity. In France and the Netherlands, production is handed over to a central mint in each case. In France it is the Monnaie de Paris, in the Netherlands the Koninklijke Nederlandse Munt. The commemorative coins are made of different materials with different denominations. Thus, there are 2 euro, 5 euro and 10 euro commemorative coins made of a copper-nickel alloy. Silver commemorative coins have a face value of 10 euros, 20 euros and 25 euros. The coins made of gold include the largest range. Here there are 20 euro coins such as the coins from the series “German Forest†or “Native Birdsâ€. The "Musical Instruments" series is covered by the €50 denomination. Furthermore, there are German commemorative coins with a nominal value of 100€ and 200€.
Mints: Monitoring of Mints
By their very nature, coin manufacturers are subject to government oversight, and they outsource some production. The German mints have production at a total of 14 locations in Germany, with one of the mints in each of the five cities mentioned being responsible.

Nugget
Nuggets are naturally formed lumps of gold or platinum. Normally they consist of small grains, but they can reach a considerable size. The largest nugget of gold had a fineness of 2316 ounces and weighed about 72 kilograms. It was found in Australia in 1869. It became famous under the name "Welcome Stranger". Later, another sensational find was made by a German mining entrepreneur. He discovered a gold nugget with a fineness of around 27 percent pure gold. The find weighed 57 kilograms. Strictly speaking, it was a quartz nugget with a high gold content. The term gold nugget is usually used in connection with a very high degree of purity. In Australia, such metal nuggets with purity grades of sometimes even more than 95 percent are frequently found. In Germany, the weight of the largest gold nugget found was around 10 kilograms, and in Russia there was a twelve-kilogram find of a platinum nugget in 1843. In most cases, melting down the large nuggets is the usual procedure.
Nugget: Origin of the Nuggets
The formation of nuggets occurs through the erosion of gold-bearing mineral rocks. Gold has a high chemical resistance, so it is insensitive to weathering and natural transport by streams or rivers. The mineral or rock surrounding it is often removed in the process, leaving the gold intact. In ores, the precious metal is usually contained in a very fine way, so that nuggets that are too large cannot be formed. For this reason, stocks of tiny pieces or dust of gold occur, which are then revealed by weathering ore.

Meanwhile, there are some coin collections in world cities like New York, Paris or London. However, also in Vienna you can find the coin cabinet of the Kunsthistorisches Museum or in Switzerland many small coin cabinets. In addition, there are some private individuals who already have considerably large collections.
Numismatics: Coins
The coins are the object that is most often studied. Especially if you want to do historical research, coins of that time provide important information about life, politics and economy.
Numismatics: History
It has been handed down by Suetonius that already more than 2000 years ago Emperor Augustus collected older coins. However, the first scientific studies were probably made in the 14th or 15th century, when, for example, the poet Petrarch dealt with them.

Rational Unified Process
A proprietary customizable iterative framework for software development processes consisting of four project phases: Conception Phase, Design Phase, Construction Phase, Handover Phase.
Red Gold
For the production of red gold is usually not used pure gold. Special alloys of gold are used here, and a special copper mixture is added to the precious metal. This creates the red and somewhat darker color of the gold. These alloys are then called red gold. In terms of color, there may well be different variants. Thus, the metal can have a reddish, orange or brownish color appearance. A light violet is also possible. Sometimes, there are still demarcations made here, so there are other designations such as rose gold or brown gold. However, the transitions are usually smooth. The reddish color is due to the high copper content. However, this fact also has some disadvantages. Copper makes the precious metal more susceptible to oxidation. For this reason, a dirty-brown discoloration occurs frequently and quickly under correspondingly unfavorable conditions.
Red Gold: Rose Gold
This precious metal usually has a fineness of about 33 to 75 percent. A higher proportion of gold causes the copper admixture to fade. In this case, the so-called rose gold is created. The percentage of copper should therefore be correspondingly higher than that of other metal additions such as silver. Too high a content, in turn, causes deterioration of the properties of the material, and the alloy oxidizes and discolors. Rose gold is very valuable, because it has a high content of gold and a lower percentage of copper. Thus, it has only a faint red coloration. Furthermore, here there is an admixture of silver, which also contributes to a coloration. The jewelry also becomes less sensitive to external influences.
Regression
A deterioration in the quality of a component or system due to changes.
Regression Test
Retesting of an already tested program or partial functionality after its modification. The goal is to prove that no error states have been introduced or (previously masked error states) exposed as a result of the changes made. Note: A regression test is performed when the software or its environment has been modified. Due to the repetitive nature and frequency of these repetitions, it makes sense for test automation to be used for regression testing. In practice, the term regression testing stands for the pure repetition of test cases. The test cases themselves must be specified and provided with a target result, which is compared with the actual result of a test case. A direct reference to the results of a previous test run does not take place.
Regulatory Acceptance Test

All documents from which the requirements imposed on a component or system can be seen, or the documentation on which the derivation or selection of test cases is based. If a document can only be changed via the formal change procedure, it is a defined test basis.
Test Case
Includes the following: the preconditions necessary for execution, the set of input values (one input value per parameter of the test object), the set of predicted results, and the expected postconditions. Test cases are developed with a specific goal or test condition in mind, such as executing a specific program path or checking conformance to specific requirements (how to pass inputs to the test object and read target values).
Test Case Group
A test case group contains a set of test cases that can be meaningfully grouped together with respect to one or more aspects. This could, for example, be test cases for a module, for a test discipline, or for specific business processes. A clever organization of test cases via test case groups is a possibility to shorten the time of test preparation for the development of test plans.
Test Case Specification
See also: test specification; A document that specifies a set of test cases for a test object (including test data and pre/post condition), where the test cases each contain objectives, inputs, test actions, predicted results, and preconditions for execution.
Test Charter
See also: exploratory testing; synonyms: charter; A statement of test objectives and possible test ideas on how to test. Test charters are often used in exploratory testing.
Test Completion
The activity that makes test assets available for later use, leaves test environments in a usable state, and communicates test results to relevant stakeholders. Test closure activities collect data from completed test activities to consolidate lessons learned, test assets, and other relevant information. Test closure activities occur at project milestones (for example, released software systems, test project completion, test stage completion, maintenance release completion, test project termination, or agile project iteration completion). Test completion deliverables include test completion reports, open items for optimization for subsequent projects, as well as iterations, change requests or product backlog entries, and the finalized test assets.
Test Completion Report
Synonyms: test report; A document summarizing test activities and results. It contains an evaluation of the tests performed against defined end criteria.
Test Concept
A document that describes, among other things, the scope, approach, resources, and timing of the intended tests with all activities. It identifies, among other things, the test objects, the features to be tested and the test tasks. It assigns the testers to the test tasks and defines the degree of independence of the testers. It describes the test environment, the test design procedures and the test measurement procedures to be used, and justifies their selection. It also describes risks that require planning for when they occur. A test concept is thus the transcript of the test planning process.
Test Condition
Synonyms: test requirement, test situation; An entity or event, e.g., a function, transaction, feature, quality attribute, or structural element of a component or system, which can be verified by one or more test cases.
Test Control
See also: test management; Test control is the management task of developing and applying corrective actions to control a deviation from the planned procedure in a test project. Test control involves taking necessary actions to achieve the objectives of the test plan (which may be updated over time). Test monitoring and control deliverables typically include continuous or periodic test progress reports and, when completion milestones are reached, the final test report. All test reports should contain details relevant to the target group about the test progress at the time of reporting and summarize the test execution results. The reports should also address project management issues such as completed tasks, resource allocation/utilization, effort, identified obstacles or blockages, etc.
Test Coverage
See also: testing process; collecting and analyzing data on testing activities and then consolidating it into a report to inform stakeholders.
Test Cycle
Execution of the test process for a single specific release of the test object.
Test Data

Test Data Editor and Generator
Synonyms: test generator; A test support tool used to generate, provide, modify, or select data from a database.
Test Design
See also: test design specification; synonyms: test design; (1) See test design specification. (2) The process of translating general test objectives into tangible test conditions (note: test conditions are identified in test analysis) and, most importantly, into test cases. During test design, test conditions are transformed into abstract test cases, sets of abstract test cases, test charters, and other test resources. The test design answers the question: "How is testing done?". The transformation of test conditions into test cases and test case sets during test design often involves the use of test procedures (test case derivation procedures). As with test analysis, test design can also lead to the identification of similar types of defects in the test base. During test design, finding corresponding defect conditions in the test base represents an important potential benefit. Results of the test design are test cases and test sets (test case groups) to cover the test conditions defined in the test analysis. Initially, one develops abstract test cases without designing concrete values for input data and expected results, which can be reused over multiple test cycles with different concrete data and still adequately document the test case scope. Each test case should be bidirectionally traceable to the test conditions it covers.
Test Design Process
Synonyms: test case design procedure, test specification procedure, test procedure, test design procedure; A procedure by which test cases are derived or selected.
Test Design Tool
A tool for generating test data either (a) based on a specification that may be stored in a CASE repository (e.g., in a requirements management tool), or (b) from specified test conditions stored in the test design tool itself, or (c) from the code itself.

Test Estimate
Determined approximation of a result on some aspect of testing (e.g., effort, end time, required cost, number of test cases, etc.) that is useful even if the input data is incomplete, uncertain, or disturbed.
Test Execution
Synonyms: test execution; The process of executing a test for a component or system that produces actual results. During test execution, test suites run in accordance with the test execution plan. Ideally, once test execution is complete, the status of each element of the test base can be determined as it relates to its associated test suites via bidirectional traceability. This answers questions about which requirements have passed all scheduled tests, which requirements have not been successfully verified and/or have error conditions due to failed tests, and which requirements are still awaiting test execution. This can be used to check coverage criteria and create test result reports that are understandable to stakeholders.

Test Monitoring
See also: test management; A test management task that refers to the periodic monitoring of test progress. Test completion reporting compares the actual situation with the plan. Test monitoring involves the ongoing comparison of actual progress with planned progress using any monitoring metrics defined in the test concept. Test monitoring and control deliverables typically include continuous or periodic test progress reports and, when completion milestones are reached, the test completion report. All test reports should contain details relevant to the target group about the test progress at the time of reporting and summarize the test execution results. The reports should also address project management issues such as completed tasks, resource allocation/utilization, effort, identified obstacles or blockages, etc.
Test Object

Test Oracle
Synonyms: oracle; source of information to determine the respective predicted results to be compared with the actual results of a software in the test. Note: A test oracle can be an existing system (as a benchmark), a user manual, or a person's specialized knowledge, but should not be the code.
Test Plan
A list of activities, tasks, or events in the testing process, indicating their planned start and end dates and their interdependencies.
Test Planning
An activity in the testing process to create and update the test concept. Test planning includes activities that define the test objectives and determine the approach for achieving the test objectives within the constraints imposed by the environment (e.g., specifying appropriate test procedures and tasks and formulating a test plan to meet a deadline). Test plans may be revised based on feedback from monitoring and control activities. Test planning work products typically include one or more test concepts that contain information about the test baseline to which the other test work products will relate via traceability information, as well as entry (also referred to as Definition-of-Ready) or exit (also referred to as Definition-of-Done) criteria that will be used during test monitoring and control.

The test log contains a record of all events that occurred during a test run or scheduled test run, as well as the status of each test point.
Test Realization
Process of developing and prioritizing (concrete) test cases, creating test data and, optionally, preparing test frameworks and writing automated test scripts. During test realization, the question is: "Is everything ready for test execution?". All test assets necessary for test execution are created and / or completed, such as test cases in test sequences are put in an optimal order. Test design and test realization tasks are often combined. Once the test realization is completed, ideally the achievement of coverage criteria defined in the test concept can be shown via the bidirectional traceability between test procedures and specific test base elements via the test cases and test conditions. Test realization usually also includes the creation and verification of test data (primary test data or test parameters; secondary test data or database contents) and the test environment. The completeness of the verification result documentation of data and / or environment can vary greatly.
Test Report

Yellow Gold
Yellow gold is a yellow gold alloy of gold with silver and copper, which give the gold a stronger hue. The lower the gold content, the more the depth of the yellow tone is reduced. Yellow gold is the most popular gold color, because it has a high recognition value and its coloration is the most similar to fine gold.
Yellow Gold: Appearance and Color Gradations
Normally, the ratio of gold and the added metals is approximately the same, i.e. one to one. With a high percentage of fine gold, the original gold tone is relatively intense and is increasingly weakened by the additions. However, the intensity of the color and the type of tint can be decided according to preference. A spectrum from very light gold with a correspondingly high silver content to a dark yellow-orange with a strong copper content is possible here.
Yellow Gold: Why?
Yellow gold is convenient because it can retain the color of the original gold and is easier to work with because of the added raw materials. Fine gold is rather soft and worse to cast than gold alloys.
Yield
