How do I set up fixtures in pytest?

To set up fixtures in pytest, you can use the @pytest.fixture decorator to define a fixture function.

Can you give me an example of a simple fixture?

Sure! Here's a simple fixture that returns a dictionary:

import pytest

def my_fixture():
    return {'key': 'value'}

How do I use this fixture in a test?

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

def test_example(my_fixture):
    assert my_fixture['key'] == 'value'

What if I need to set up some resources before running tests?

You can use the scope parameter in the fixture decorator to control the setup and teardown of resources.
