How can I use pytest-mock for advanced testing scenarios?

You can use pytest-mock to create complex mocks and stubs for your tests. What specific scenario are you working on?

I need to mock a function that interacts with a database. How do I do that?

You can use the mocker.patch method to replace the database function with a mock. Would you like a code example?

Yes, please provide a code example for mocking a database call.

Sure! Here's a simple example:

from mymodule import db_function

def test_db_function(mocker):
    mocker.patch('mymodule.db_function', return_value='mocked result')
    assert db_function() == 'mocked result'
