Answer
Mocking boundaries is preferred to maintain test stability.
Mocking at the boundaries of your system (e.g., external APIs) rather than internal components keeps tests stable and focused on the behavior. Over-mocking internals can lead to brittle tests that need frequent updates. In an e-commerce system, mock the API interactions but avoid mocking internal methods of complex objects like OrderProcessor unless necessary.
