I have had a weird thought lately about testing at runtime. My thought is just to log violations of expectations- i.e. log when the test would have failed.

This doesn’t prevent the bug from being introduced but can remove a huge amount of complexity for test cases that are hard to set up.

Sounds a bit like "design by contract", leaving the assertions enabled in production code. It would be great to have solid DbC support in mainstream languages.
