How can I use advanced fixtures in pytest?

Advanced fixtures in pytest allow you to create reusable setup code for your tests. You can use fixtures to manage resources like databases or web servers.

Can you give me an example of a fixture that uses a database connection?

Sure! You can create a fixture that sets up a database connection like this:

import pytest

@pytest.fixture
def db_connection():
    connection = create_db_connection()
    yield connection
    connection.close()

How do I use this fixture in my tests?

You can use the fixture in your test function by adding it as a parameter:

def test_query(db_connection):
    result = db_connection.query('SELECT * FROM users')
    assert result is not None

What if I need to use multiple fixtures in a single test?

You can simply add multiple fixture parameters to your test function. For example:

def test_multiple_fixtures(db_connection, another_fixture):
    # Your test code here
