PyTest - Fixtures

What is wrong with this pytest fixture usage?

import pytest

@pytest.fixture(scope='session')
def setup_api():
    print('Setup API')

class TestAPI:
    def test_one(self):
        setup_api()

ASession scope fixtures cannot be used in classes.

BFixture must be passed as a test function argument, not called directly.

CFixture function must return a value.

DFixture name must start with 'test_'.

Step-by-Step Solution

Solution:

Step 1: Understand fixture usage in pytest
Fixtures are injected by pytest as function arguments, not called directly inside test functions.
Step 2: Identify incorrect usage
Calling setup_api() directly inside test_one bypasses pytest fixture mechanism and will not work as intended.
Final Answer:
Fixture must be passed as a test function argument, not called directly. -> Option B
Quick Check:
Use fixtures as function arguments, not direct calls [OK]

Quick Trick: Pass fixtures as test arguments, don't call them directly [OK]
