Testing where it counts
More tests isn't the goal — trustworthy tests are. Two notes on getting real protection without drowning in green checkmarks.
1. Test behavior, not lines
Coverage numbers feel good and prove little. Test the things that would actually hurt if they broke — the checkout, the auth, the money math — and don't chase a percentage by testing getters and setters.
2. Kill flaky tests fast
A test that fails at random is worse than no test — it teaches the team to ignore red. Fix it or delete it. A suite people trust is the entire point of having one.
