User Acceptance Testing (UAT)
User Acceptance Testing (UAT) is the final testing phase where business users validate whether a system meets business requirements and is ready for production.
Also known as: UAT, Acceptance Testing, User Validation Testing
Full Definition
User Acceptance Testing (UAT) is a critical validation process conducted before production deployment to ensure that a software application, product, or system satisfies business requirements, workflows, and user expectations. During UAT, real users or business stakeholders execute predefined scenarios to verify functionality, usability, integrations, and operational readiness. UAT helps identify gaps between technical implementation and business needs, reduces deployment risks, and ensures the delivered solution is fit for real-world use.
