🔬Mocking is a valuable tool in test driven development, allowing us to measure interactions between code parts.
⚠️Mocking can be misused, leading to tight coupling and complicated dependencies.
⚡️Mocking third-party code is risky and should be avoided.
🧩Good design in test driven development is about managing complexity and minimizing conversation between code parts.
🌟Good design hides implementation details and focuses on measuring the interactions that matter.
