PyTest - Parametrize

What is wrong with this pytest code snippet?

@pytest.fixture
def setup_data(request):
    return request.param + 1

@pytest.mark.parametrize('setup_data', [10, 20])
def test_increment(setup_data):
    assert setup_data in [11, 21]

AThe fixture should not return a value.

BFixture name and parameter name must be different.

CMissing indirect=True in parametrize to pass parameters to fixture.

DThe assert statement is incorrect.

Step-by-Step Solution

Solution:

Step 1: Check parametrize usage with fixture
Parameters must be passed indirectly to fixtures using indirect=True.
Step 2: Identify missing indirect=True
The code lacks indirect=True, so parameters go directly to test, not fixture.
Final Answer:
Missing indirect=True in parametrize to pass parameters to fixture. -> Option C
Quick Check:
indirect=True needed to use request.param [OK]

Quick Trick: Add indirect=True to parametrize when using request.param [OK]

Common Mistakes:

MISTAKES

Forgetting indirect=True causes request.param error
Thinking fixture and param names must differ
Assuming fixture cannot return values
