Testing Reveals 41% of Faults Go Undetected in Newer Python Libraries

Testing 50 Python libraries with 2,312 planted faults found that tests in newer libraries miss 41% of them, and surfaced four real library problems, including a Windows data-loss bug and README examples that don't work as written. That's a strong signal: young codebases need more than just test coverage. For a deeper look at how evaluation gaps mislead us, see our related piece on search accuracy. The takeaway is simple, test your tests.
