PyTest - Fixtures

You have a fixture defined in conftest.py as follows:

import pytest

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

In your test file, you wrote:

def test_sum(data):
    assert sum(data) == 10

What is the problem and how to fix it?

AAssertion is wrong; sum([1,2,3]) is 6, so change 10 to 6

BFixture not imported; add <code>from conftest import data</code>

CFixture must be a class, not a function

Dsum() cannot be used on lists

Step-by-Step Solution

Solution:

Step 1: Check the fixture return value
The fixture data returns the list [1, 2, 3].
Step 2: Calculate the sum and compare with assertion
sum([1, 2, 3]) equals 6, but the test asserts it equals 10, which is incorrect.
Final Answer:
Assertion is wrong; sum([1,2,3]) is 6, so change 10 to 6 -> Option A
Quick Check:
sum([1,2,3]) = 6, fix assertion [OK]

Quick Trick: Verify expected values match fixture data [OK]
