User acceptance testing, or UAT, is a process by which new software or updates to existing software are tested by actual users. This is in contrast to other types of testing, such as system testing and regression testing, which are done by QA teams. UAT is considered the final stage of quality assurance before software goes into production. It can occur at any point in the development lifecycle, although it typically happens toward the end.
What is user acceptance testing?
UAT is often confused with user interface testing (UI testing). While UI testing does involve actual users, what distinguishes UAT from UI testing is that UAT occurs after all other software tests have been completed and fixed. This ensures that what’s being tested by a typical user isn’t adversely affected by bugs or errors leftover from earlier stages of QA. During UAT, business requirements are verified to ensure they are met before deployment into production. That means if product owners find anything they don’t like about what they see during this phase—including things as seemingly trivial as typos or improper spacing.
