PyTest - Parametrize

Given the code below, what will be printed when running the test?

import pytest

@pytest.fixture
def data(request):
    return request.param * 2

@pytest.mark.parametrize('data', [3, 5], indirect=True)
def test_double(data):
    print(data)

A6 and 10

B3 and 5

CNone and None

DError: request.param not found

Step-by-Step Solution

Solution:

Step 1: Understand fixture with request.param
The fixture data returns request.param * 2, so it doubles the parameter.
Step 2: Parametrize with indirect=True
Parameters 3 and 5 are passed to the fixture, so the test receives 6 and 10.
Final Answer:
6 and 10 -> Option A
Quick Check:
Fixture doubles param: 3*2=6, 5*2=10 [OK]

Quick Trick: Indirect param goes to fixture; fixture doubles it [OK]

Common Mistakes:

MISTAKES

Thinking parameters go directly to test, so expecting 3 and 5
Assuming request.param is unavailable causing error
Confusing fixture return with test parameter
