* **Stubs**: Simplest form, returning a hardcoded value or providing an empty method body. |

* **Fake object**: Include minimal logic to handle different case scenarios. |

|
-* **Spy**: Records internal data of the unit being tested when such data is not directly accessible. |

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

** 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. |

** Prefer many small classes/units to one large one for easier testing. |
