User Acceptance Testing (UAT)

User Acceptance Testing is where end users test a system against real business scenarios to confirm it meets their needs before deployment. UAT is the final quality gate before go-live.

Objectives:

• Verify the system meets business requirements
• Confirm it works in realistic scenarios
• Identify usability issues technical testing may miss
• Build user confidence before go-live
• Provide formal acceptance for deployment

UAT process:

1. Planning: Define scenarios, participants, timeline, success criteria
2. Preparation: Set up test environment, create test data, brief testers
3. Execution: Users run scenarios and record results
4. Defect management: Log, prioritise, and resolve issues
5. Sign-off: Formal acceptance for deployment
6. Transition: Move to production with user confidence

Types of UAT:

• Alpha testing: Internal users in a controlled environment
• Beta testing: External users in real-world conditions
• Contract acceptance: Verifying against contract specifications
• Regulation acceptance: Confirming regulatory compliance

Best practices:

• Use real business scenarios, not just technical tests
• Involve actual end users, not just managers
• Provide clear test scripts plus exploratory testing time
• Define pass/fail criteria before testing
• Allocate sufficient time - rushing UAT leads to post-launch issues
• Use a test environment that mirrors production
