What are some best practices for writing readable and maintainable tests?

Short answer: Use clear, descriptive names; keep tests small and focused; avoid logic inside tests; use setup/teardown methods for common code; and ensure tests are independent and deterministic.

Real-world example (ShopNest)

Arrange a cart with 2 items → Act Checkout() → Assert total and that payment was called once.

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.
