UAT is conducted through a series of predefined test cases that reflect the real-world usage of the application. These test cases are derived from user stories, business requirements, and use cases. The process typically involves the following steps: 1. Planning: Define the scope, objectives, and criteria for UAT. 2. Designing Test Cases: Develop detailed test cases and scenarios based on business requirements. 3. Environment Setup: Prepare the testing environment that mirrors the production environment. 4. Execution: Execute test cases and document any issues or defects. 5. Review and Sign-off: Review the results and obtain sign-off from stakeholders to confirm that the system is ready for release.
