How to find the average percentage of faults detected (APFD) for test cases in open source projects?

I'm practicing test case prioritization techniques. To get real results, I need some metrics for test cases such as the average percentage of faults detected (APFD), APFD per cost, and so on. To to find these data for open source projects?

Note that I have the code and the test cases, however, I'm not sure how to find the history of fault detection for each test case.

Thank you,
