An approach is provided to identify test cases based on changed test code. In the approach, test cases are compared to a current test environment that includes an instrumented software program that results in matching test cases. Matching test cases are selected based on a detection of one or more substantive changes to the current test environment. The current test environment is tested using the selected test cases.
