What are pytest mock fixtures?

Can you explain what pytest mock fixtures are?

Sure! Pytest mock fixtures are used to create mock objects for testing in Python. They help isolate tests by providing controlled inputs.

You can create a mock fixture using the @pytest.fixture decorator. Define a function that returns the mock object.

Can you give me an example of a mock fixture?

Absolutely! Here's a simple example:

import pytest

@pytest.fixture
def mock_db():
    return MockDatabase()  # Replace with your mock database class

You can use the mock fixture by including it as an argument in your test function. For example:

def test_database(mock_db):
    assert mock_db.query() == expected_result
