How can I use pytest for advanced testing scenarios?

You can use pytest for advanced testing by leveraging fixtures, parameterization, and plugins. Would you like to know more about any specific feature?

What are fixtures and how do they work in pytest?

Fixtures in pytest are functions that run before your tests to set up any state you need. You can define them using the @pytest.fixture decorator.

Can you give me an example of a parameterized test?

Sure! You can use the @pytest.mark.parametrize decorator to run a test with different sets of parameters. For example:

@pytest.mark.parametrize('input,expected', [(1, 2), (2, 3)])
def test_increment(input, expected):
    assert increment(input) == expected

What plugins do you recommend for pytest?

Some popular pytest plugins include pytest-cov for coverage reports, pytest-mock for easier mocking, and pytest-xdist for parallel test execution.
