GUARDING CODE CHECK-IN WITH TEST CASE EXECUTION RESULTS

A mechanism for providing a source code control system that employs test case execution results to mandate that software code have a specific level of quality for check-in to a central repository. A request to check-in a modified copy of a source code file to a repository is received, wherein the modified copy comprises changes to the source code file located in the repository. The modified copy of the source code file is placed in a quality check pending state in the repository. Responsive to an occurrence of a specific event or expiration of a set time period, applicable regression test cases are executed against the changes in the modified copy. A determination is made as to whether the regression test cases are successful. If the regression test cases are successful, the changes in the modified copy are committed to the source code file located in the repository.
