Test generation is one of the clearest wins: mechanical, tedious, and easy to verify. The tools read a function and produce cases including the edge conditions people skip.
Generated tests that assert current behavior lock in bugs as well as features. Read them before you commit them.
Analyze, share, and automate code reports for improved quality and security.
