[Solved] Identify the error in the following pytest code: import pytest @pytest.fixture def data(): return [1, 2, 3] def test_sum(): result = data + [4] assert sum(result) == 10 | PyTest

PyTest - Fixtures

Identify the error in the following pytest code:

import pytest

@pytest.fixture
def data():
    return [1, 2, 3]

def test_sum():
    result = data + [4]
    assert sum(result) == 10

AThe fixture 'data' should return a tuple, not a list

BThe fixture decorator is missing

CThe assertion is incorrect; sum should be 9

DThe fixture 'data' is not passed as a function argument to the test

Step-by-Step Solution

Solution:

Step 1: Check fixture usage in test
The fixture 'data' is defined but not passed as an argument to 'test_sum', so 'data' is undefined in the test.
Step 2: Identify the error caused
Trying to add 'data' (a function) to a list causes a TypeError because 'data' is not called or injected.
Final Answer:
The fixture 'data' is not passed as a function argument to the test -> Option D
Quick Check:
Fixture must be function argument = error if missing [OK]

Quick Trick: Always pass fixture as test function argument [OK]
