Fixture scope (function, class, module, session) in PyTest - Interactive Code Practice

Practice - 5 Tasks

1fill in blank

easy

Complete the code to set a fixture with function scope.

PyTest

import pytest

@pytest.fixture(scope=[1])
def sample_fixture():
    return 42

💡 Hint

Common Mistakes

Choosing 'class' or 'module' which run less frequently than function scope.

Using 'session' which runs once per test session.

The default fixture scope is function, which means the fixture is called once per test function.

medium

Complete the code to set a fixture with class scope.

PyTest

import pytest

@pytest.fixture(scope=[1])
def class_fixture():
    return 'class level resource'

Drag options to blanks, or click blank then click option'

💡 Hint

Common Mistakes

Confusing class scope with function or module scope.

Using 'session' which is broader than class scope.

Class scope means the fixture is created once per test class and shared among all test methods in that class.

3fill in blank

hard

Fix the error in the fixture scope to make it run once per module.

PyTest

import pytest

@pytest.fixture(scope=[1])
def module_fixture():
    return 'module resource'

Drag options to blanks, or click blank then click option'

💡 Hint

Common Mistakes

Using 'class' scope which runs once per class, not per module.

Using 'session' which runs once per entire test session.

Module scope means the fixture is created once per Python module and shared among all tests in that module.

4fill in blank

hard

Fill both blanks to create a session-scoped fixture and use it in a test.

PyTest

import pytest

@pytest.fixture(scope=[1])
def session_fixture():
    return 'session resource'

def test_example([2]):
    assert session_fixture == 'session resource'

Drag options to blanks, or click blank then click option'

💡 Hint

Common Mistakes

Not matching the fixture name in the test function parameter.

Using wrong scope like 'function' for session-wide resource.

The fixture is declared with session scope to run once per test session. The test function must accept the fixture name session_fixture as a parameter to use it.

5fill in blank

hard

Fill all three blanks to create a module-scoped fixture, use it in a test, and assert its value.

PyTest

import pytest

@pytest.fixture(scope=[1])
def mod_fixture():
    return 100

def test_mod([2]):
    assert [3] == 100

Drag options to blanks, or click blank then click option'

Dfunction

💡 Hint

Common Mistakes

Using wrong scope like 'function' instead of 'module'.

Mismatching fixture name in test function parameter or assertion.

The fixture has module scope, so it runs once per module. The test function uses the fixture by naming it mod_fixture as a parameter, and asserts that the fixture value equals 100.
