Test case repository is a database containing all the test cases that have been created so far. Having a test case repository is highly beneficial. Firstly, it makes test case execution faster and quicker. Since in certain cases the previously run test cases can be reused to achieve results. This saves ample of time of the testers.

Secondly the test cases and test document can be kept for future reference. A test case repository is an added benefit for companies that opt for outsourced testing services.
