If you want to write a test that sets one or more environment variables, overriding existing values, you can use mock.patch.dict like this: You can apply this to all tests in a module by creating a local auto-used pytest fixture that uses mock.patch.dict: If you dont know the keys or values you want to mock at import time, youll need to use the context manager form of mock.patch.dict within your test function: If you want to clear everything from os.environ so only the given variables are set, you can do so by passing clear=True to mock.patch.dict: If you want to remove only a few variables, it gets a little more tricky. form of a tuple: the first member, which can also be accessed through detect the synchronous functions and set them as MagicMock (if the any set return value, then there are two ways of doing this.
