[Solved] Identify the error in this pytest fixture usage: import pytest @pytest.fixture def resource(): return open('file.txt', 'r') def test_read(resource): data = resource.read() assert data != '' resource.... | PyTest

PyTest - Fixtures

Identify the error in this pytest fixture usage:

import pytest

@pytest.fixture
def resource():
    return open('file.txt', 'r')

def test_read(resource):
    data = resource.read()
    assert data != ''
    resource.close()

AThe fixture should close the file after test automatically

BThe fixture is missing the @pytest.fixture decorator

CThe test should not use the fixture as a parameter

DThe assert statement is invalid syntax

Step-by-Step Solution

Solution:

Step 1: Analyze resource fixture and test
The fixture opens a file but does not close it. The test closes it manually.
Step 2: Understand best practice for cleanup
Fixtures should handle cleanup automatically using yield or finalizers to avoid resource leaks if test fails before close.
Final Answer:
The fixture should close the file after test automatically -> Option A
Quick Check:
Fixtures manage setup and cleanup [OK]

Quick Trick: Use fixture finalizers or yield for cleanup [OK]
