How do you convince a team resistant to testing to adopt unit tests?

Short answer: I highlight the long-term benefits like reduced bugs, easier refactoring, and faster debugging. Demonstrating quick wins with simple tests and integrating tests gradually helps ease resistance.

Real-world example (ShopNest)

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

Say this in the interview

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.
