Chasing a test-coverage number is a good way to write a lot of tests that protect nothing important.

Coverage counts lines, not risk. You can test every getter and setter in the codebase and still ship the bug that double-charges a customer, because nobody tested the one path where money moves.

We test what breaks. The paths that touch money, permissions, data integrity and anything hard to undo get thorough tests first. Cosmetic code gets a light touch or none.

The result is a smaller test suite that fails for reasons that matter. A red build should mean something is genuinely wrong, not that a label changed. Tests you trust are the only tests worth running.
