3 -* **Mocking simplifies unit testing by replacing the dependencies** of the unit being tested with simplified, simulated versions called mocks. Example: Consider a unit under test that relies on a database. In testing, the database can be mocked to return a static value, eliminating the need for an actual database.

21 21  * **Stubs**: Simplest form, returning a hardcoded value or providing an empty method body.
22 22  * **Fake object**: Include minimal logic to handle different case scenarios.
23 -* **Spy**: Records internal data of the unit being tested when such data is not directly accessible.
24 -* **Mock object**: Contains complex logic, simulates behaviors such as computation and exception handling, and can even run tests.

30 -* **Mock third-party libraries in unit tests** to ensure proper unit functionality. However, they should not be mocked in component and integration tests.
26 +* **Mock third-party libraries in unit tests** to ensure proper unit functionality. Instead, use these libraries in component and integration tests.
31 31  * Aim for a **minimal number of dependencies in a unit** for easier testing and mocking:
32 32  ** Limit dependencies in a unit in a similar way to the best practices for function arguments: the fewer the better, with an absolute maximum of three.
33 33  ** Prefer many small classes/units to one large one for easier testing.
