Beta testing is one of the acceptance testing methodologies conducted by customers to assess the level of their satisfaction with the project. It involves end users who use the product, over a certain period of time to check its functionality, usability, reliability, and compatibility. Beta testing is usually performed immediately after completing the alpha testing.
During the testing product and after it, the experience of working with the application gained by end users is taken into account, and feedback on the design, as well as on the functionality and interface is requested. All this helps to assess the quality of the final product since a pre-release working version of the application with full functionality is provided for beta testing.
