Parametrize with indirect fixtures in PyTest - Interactive Code Practice

Practice - 5 Tasks

1fill in blank

easy

Complete the code to parametrize the test with indirect fixture usage.

PyTest

import pytest

@pytest.fixture
def data(request):
    return request.param

@pytest.mark.parametrize('data', [1, 2, 3], [1]=True)
def test_example(data):
    assert data in [1, 2, 3]

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

💡 Hint

Common Mistakes

Using 'params' instead of 'indirect' causes pytest to treat values as direct parameters.

Forgetting to set indirect=True means the fixture is not used.

The 'indirect=True' argument tells pytest to treat the parameter 'data' as a fixture and pass the values to it.

medium

Complete the code to access the parameter inside the fixture using the request object.

PyTest

import pytest

@pytest.fixture
def setup_data([1]):
    return request.param * 2

@pytest.mark.parametrize('setup_data', [4, 5], indirect=True)
def test_double(setup_data):
    assert setup_data in [8, 10]

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

💡 Hint

Common Mistakes

Using 'param' or 'data' as argument instead of 'request' causes errors.

Trying to access 'param' without the request object.

The fixture receives the 'request' object which contains the parameter in 'request.param'.

3fill in blank

hard

Fix the error in the test by correctly marking the parameter for indirect fixture usage.

PyTest

import pytest

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

@pytest.mark.parametrize('config', [10, 20], [1]=True)
def test_config(config):
    assert config in [11, 21]

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

💡 Hint

Common Mistakes

Omitting 'indirect=True' causes the test to fail because the fixture is not used.

Using 'params' instead of 'indirect' causes wrong behavior.

The 'indirect=True' argument is required to tell pytest to use the fixture 'config' with the parameter values.

4fill in blank

hard

Fill both blanks to parametrize two fixtures indirectly.

PyTest

import pytest

@pytest.fixture
def user(request):
    return request.param

@pytest.fixture
def role(request):
    return request.param

@pytest.mark.parametrize('user, role', [('alice', 'admin'), ('bob', 'user')], [1]=[2])
def test_access(user, role):
    assert user in ['alice', 'bob']
    assert role in ['admin', 'user']

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

💡 Hint

Common Mistakes

Using 'indirect=False' disables indirect fixture usage.

Using 'scope' instead of 'indirect' causes errors.

To parametrize multiple fixtures indirectly, use 'indirect=True' in parametrize.

5fill in blank

hard

Fill all three blanks to parametrize a test with indirect fixtures and access the parameter inside the fixture.

PyTest

import pytest

@pytest.fixture
def item([1]):
    return request.param * 3

@pytest.mark.parametrize('item', [2, 3], [2]=[3])
def test_item(item):
    assert item in [6, 9]

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

CTrue

Dparams

💡 Hint

Common Mistakes

Not accepting 'request' in the fixture causes errors.

Omitting 'indirect=True' disables fixture parameterization.

The fixture must accept 'request' to access 'request.param'. The parametrize decorator uses 'indirect=True' to apply parameters to the fixture.
