Beta testing is the intensive exploitation of an almost finished version of a product in order to identify the maximum number of errors in its operation for their further fix before the final release of the product to the market, i.e. to the mass consumer. Beta testing is a real working version of the program with full functionality. The purpose of beta tests is to evaluate the capabilities and stability of the application from the point of view of its future users.
Beta testing is performed by interested people, in other words, a group of testers who sign up to test the company's applications and are given access to the application. Access to testing is provided by the company for free, and the company may also give testers some bonuses. Those interested in participating in beta testing are called beta testers.
Beta testers can use the documentation for the tested application. Suppose beta testers find any errors, failures, or crashes. In that case, they notify the company's employees as soon as possible and provide a detailed description of the bug and the actions that led to the defect. This is called feedback between the beta testing group and the company. Beta testing can help to detect new bugs and provide feedback on how the program works in general.
