The User Acceptance Testing Checklist is a tool to help ensure that an application, system, or product meets the needs of the users. It includes a list of criteria that needs to be tested and is often used as part of a formal process. The list can include functionality, usability, performance, security, and other criteria. The checklist should be tailored to the application, system, or product being tested and should be used in conjunction with other methods such as interviews and surveys. By using the checklist, organizations can verify that the application or system meets the user's requirements before deployment.
