What are the potential downsides of over-mocking in tests?
- Overhead of writing and maintaining complex mock setups.
- Increased test coverage and confidence.
- Reduced test readability.
- Improved code maintainability.
Over-mocking in tests can lead to the overhead of writing and maintaining complex mock setups, which can make tests harder to understand and maintain. Candidates should explain that excessive use of mocking can obscure the actual behavior of the code being tested and make tests more brittle. They may also mention that it's important to strike a balance between mocking and testing real implementations to ensure meaningful and maintainable tests.
