You are tasked with creating tests for a complex system with multiple interacting components. How would you decide which components to mock or stub to achieve a balance between test isolation and reliability?
- Mock all components to ensure complete isolation
- Stub only the most complex components
- Mock components that are external or slow
- Stub components that are stable and well-tested
When testing a complex system, it's essential to strike a balance between test isolation and reliability. Mocking all components can lead to over-fragmented tests and make maintenance difficult. Stubbing only the most complex components may not ensure adequate coverage. To achieve this balance, you should mock components that are external or slow, as these can introduce variability and slow down tests. Stubbing components that are stable and well-tested can help reduce unnecessary complexity and speed up test execution.
