The Release Testing Checklist is a document used to assess the readiness of an application or software before it is released to the public. This document outlines the tests that need to be completed, such as functional testing, compatibility testing, security testing, and performance testing. Additionally, the checklist may include a list of features that need to be tested, as well as the criteria for evaluating the results of the tests. The Release Testing Checklist also includes details of any issues that need to be addressed before the product is released. Finally, the checklist should include any documentation needed during the testing process.
