How do you manage dependencies in integration tests?

Short answer: Leverage dependency injection to replace real services with test implementations or mocks. Use setup and teardown methods to initialize and dispose of dependencies per test.

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.
