User acceptance testing is the process of assuring that the proposed solution works for the user group. This type of testing is not the same as system testing. If user acceptance testing is satisfactory, the user agrees that the software or system works. UAT also refer to the process as Beta testing. It is important that this type of testing process be done by the client in an environment that is as near to a real life scenario as possible. For your information, the user in the Beta test will prepare a summary of findings of the results and in the whole scheme of things, this process is one of the final elements of the testing program.
User acceptance testing is the last step in the verification of business functionality and functioning of the system. It behaves the same as it would in the real world, on behalf of the client, or one of their sizable customers. When the product in question operates as intended and doesn’t exhibit significant issues during the Beta testing phase, we are confident that there will be the same level of quality when in normal use.
The testing process, because it is performed by the client, or by those who are, or will be, end users, don’t typically deal with simple errors or issues. Spelling errors and cosmetic problems are not serious enough to stop the process. Beta testing assumes that major defects would have already been fixed during the earlier testing processes, so software crashes are examples of defects that would not be present when Beta testing is implemented.
