How do you handle flaky tests in your testing suite?

Short answer: Identify and fix root causes like race conditions or dependencies on external systems. Use mocking, isolate tests, avoid shared state, and if necessary, temporarily quarantine flaky tests while prioritizing fixes.

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.
