A software release life cycle is the sum of the stages of development and maturity for a piece of computer software: ranging from its initial development to its eventual release, and including updated versions of the released version to help improve software or fix software bugs still present in the software. A” test was the verification of a new product before the public announcement. B” test was the verification before releasing the product to be manufactured. C” test was the final test before the general availability of the product. Pre-alpha refers to all activities performed during the software project before formal testing.
These activities can include requirements analysis, software design, software development, and unit testing. In this phase, developers generally test the software using white-box techniques. Alpha software can be unstable and could cause crashes or data loss. Alpha software may not contain all of the features that are planned for the final version. Beta, named after the second letter of the Greek alphabet, is the software development phase following alpha. Software in the beta stage is also known as betaware. Beta phase generally begins when the software is feature complete but likely to contain a number of known or unknown bugs.

Beta testers are people who actively report issues of beta software. They are usually customers or representatives of prospective customers of the organization that develops the software. Beta testers tend to volunteer their services free of charge but often receive versions of the product they test, discounts on the release version, or other incentives. As the Internet has facilitated rapid and inexpensive distribution of software, companies have begun to take a looser approach to use of the word “beta”.
In 1984, Stephen Manes wrote that “in a brilliant marketing coup, Bruce and James Program Publishers managed to get people to pay for the privilege of testing the product. In September 2000 a boxed version of Apple’s Mac OS X Public Beta operating system was released. Windows Vista, between September 2005 and May 2006. Throughout 2009 to 2011, Minecraft was in public beta.
On December 29, 2014, all owners of Halo: The Master Chief Collection for the Xbox One were able to download and play the Beta of Halo 5: Guardians for free through January 18, 2015. Open betas serve the dual purpose of demonstrating a product to potential consumers, and testing among an extremely wide user base likely to bring to light obscure errors that a much smaller testing team might not find. In this stage of product stabilization, all product features have been designed, coded and tested through one or more beta cycles with no known showstopper-class bugs. Once released, the software is generally known as a “stable release”. The formal term often depends on the method of release: physical media, online release or a web application. The term “release to manufacturing”, also known as “going gold”, is a term used when a software product is ready to be delivered. This build may be digitally signed, allowing the end user to verify the integrity and authenticity of the software purchase.
A copy of the RTM build known as the “gold master” or GM is sent for mass duplication if applicable. No physical media are produced in this type of release mechanism by the manufacturer. Web releases are becoming more common as Internet usage grows. During its supported lifetime, software is sometimes subjected to service releases, patches or service packs, sometimes also called “interim releases”. When software is no longer sold or supported, the product is said to have reached end-of-life, to be discontinued, retired, deprecated, abandoned, or obsolete, but user loyalty may continue its existence for some time, even long after its platform is obsolete—e.
