What is code coverage threshold you follow in your projects?

Short answer: Typically, I aim for at least 80% coverage on critical code paths, but focus more on meaningful coverage rather than just numbers. Coverage alone doesn’t guarantee quality.

Real-world example (ShopNest)

ShopNest unit tests cover pricing and discount rules so a bad coupon change fails in CI before customers see it.

1. Define — one clear sentence (the short answer above).
2. Example — relate it to a project like ShopNest or your real work.
3. Trade-off — when you would not use it.
