As we are trying to test our "units" of code independently, we want to make sure that we do not rely objects and data generated by "external" code.

This means that they will happily allow the access to any attribute or method and provide a mocked value in return. One downside to this is that if the code you are testing gets the name of the attribute wrong, your mock object will not complain and the test may still pass. -In order to avoid that, we have defined a number of Mock types in [`helpers.py`](/tests/helpers.py) that follow the specifications of the actual Discord types they are mocking.
