Deep dives

Understanding Mocking and Its Components

Mocking is a technique used in software testing to replace parts of a system with alternative implementations to test specific functionalities without side effects. It is essential to understand the differences between various terms: mocks, stubs, spies, and fakes, as each serves a unique purpose. For example, a stub mimics a function without executing its code, while a spy allows testing how a function is called while still executing it. Recognizing these distinctions helps in deciding when to implement each type of mock to enhance testing effectiveness and clarity.
