What is User Acceptance Testing?

User Acceptance Testing (UAT) is a crucial stage of testing that occurs before the release of software. It involves users validating whether the product works and meets their requirements. UAT can take various forms, such as releasing new features to a subset of users or conducting rounds of testing in a production mirror environment. The primary aim of UAT is to anticipate any bugs, errors, or confusing elements before the software's release. It helps ensure that the product is polished and functional without needing constant revamping. UAT is critical for successful application or feature releases, with 88% of respondents in a survey stating its importance in achieving quality objectives.
