How can I handle errors when using pytest-mock?

You can handle errors in pytest-mock by using the side_effect attribute to raise exceptions when a mock is called.

Can you give me an example of that?

Sure! You can define a mock like this: mock_function.side_effect = ValueError('An error occurred'). This will raise a ValueError when the mock is called.

What if I want to test multiple exceptions?

You can use a list for side_effect. For example: mock_function.side_effect = [ValueError('Error 1'), TypeError('Error 2')].

Is there a way to assert that the correct exception was raised?

Yes! You can use pytest.raises to assert that the correct exception is raised during the test.
