From Requirement Functional Businees Logic Desing Level Documents Testers wrote Test cases with the Requiremnet Traceability Matrix. once all the Test cases are covered according to the Requirment. QA team review the test cases and got approved by Updating/Deleting the Test cases. Those Test cases are ready to test. Once the Project Build/ Sanity is ready the test cases are ready to execute.
How do you know what test cases you need to run for a project?
it depends on the project scope but in general we do write test cases on Build Acceptance Testing Functional Testing Integration Testing performance Testing end to end scenarios Testing etc.
As a tester we are going to test the appropriate form or module in that we are going to check mainly the functionality based on the SRS So by comparing with SRS we know what are all the main things in a project that need testing for that we want to write the test cases based on the SRS.
SRS is the parent document for writing test cases to an AUT. A minimum of one test case is must needed for a requirement so that when all the requirements are covered with respect to test cases which can be mapped with the help Traceability Matrix.
