Английский разговорный словарь (основной) - alpha test

noun and verb (Science and Technology) noun: A preliminary test of an experimental product (such as computer software), usually carried out within the organization developing it before it is sent out for beta testing. transitive verb: To submit (a product) to an alpha test. Etymology: Formed by compounding. Alpha, the first letter of the Greek alphabet, has long been used to denote the first in a series; the alpha test is the first test in a routine series. History and Usage: The concept of the alpha test comes from the world of computer software development, where it has been used since the early eighties. Its purpose is to iron out as many bugs as possible before allowing the software to be used by outsiders during the second phase of testing (see beta test). A person whose job is to test software in this way for the developer is an alpha-tester; the process is known as alpha testing and the product at this stage of development is the alpha-test version. As the operations manager for a large computer equipment manufacturer, Ray Majkut helped oversee the 90-day test of a 200-line private branch exchange, an experience he regarded as more of an alpha test than a beta test.
