An advanced stage of the software release life cycle. Beta testing is carried out when the application is feature complete and close to the finished version. The purpose of testing is to identify the maximum number of bugs and errors in the program operation. Unlike alpha testing, which is usually carried out by the developers, this stage involves third-party testers, including future users of the product. As a rule, beta testing participants are not offered material incentives, but sometimes receive privileges and bonuses on buying the final version of the program.
