3 3  * Mocking simplifies unit testing by replacing the dependencies of the unit being tested with simplified, simulated versions called mocks.
4 4  * 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.

26 -* **Mock object**: Contains complex logic, simulates behaviors such as computation and exception handling, and can even run tests.

32 -* **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.
33 33  * Aim for a **minimal number of dependencies in a unit** for easier testing and mocking:
34 34  ** 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.
35 35  ** Prefer many small classes/units to one large one for easier testing.
