The end-user evaluates the software's functioning to determine whether it is satisfactory. After functional and regression testing, this is the last and last phase. UAT is also known as end-user testing or beta testing. UAT is also known as end-user testing or beta testing. The necessity for UAT originates from the fact that developers may have constructed software based on their interpretation of requirements documents, and subsequent needed modifications throughout development may not have been successfully explained to them.
