Common Mistakes

Using @pytest.test instead of @pytest.fixture

Forgetting the decorator entirely

The @pytest.fixture decorator marks a function as a fixture, making it reusable for test setup.

Complete the test function to use the sample_data fixture as a parameter.

def test_sum([1]):
    assert sum(sample_data) == 6

Common Mistakes

Using a different parameter name than the fixture

Not including the fixture as a parameter

To use a fixture in pytest, include its name as a parameter in the test function.

Fix the error in the fixture usage by completing the code to return the correct data.

PyTest

@pytest.fixture
def numbers():
    return [1]

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

A[1, 2, 3]

B1, 2, 3

C{1, 2, 3}

D(1, 2, 3)

💡 Hint

Common Mistakes

Returning multiple values separated by commas without brackets

Returning a set instead of a list

The fixture should return a list, so use square brackets [] to return [1, 2, 3].

4fill in blank

hard

Fill both blanks to create a fixture that sets up a dictionary and a test that uses it.

PyTest

@pytest.fixture
def [1]():
    return {'name': 'Alice', 'age': 30}

def test_user_info([2]):
    assert user['name'] == 'Alice'

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

💡 Hint

Common Mistakes

Using different names for fixture and test parameter

Not matching the fixture name in the test function

The fixture is named user and the test function uses user as parameter to access the fixture data.

5fill in blank

hard

Fill all three blanks to create a fixture that sets up a list and a test that checks its length and content.

PyTest

@pytest.fixture
def [1]():
    return ['apple', 'banana', 'cherry']

def test_fruits([2]):
    assert len(fruits) == [3]

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

💡 Hint

Common Mistakes

Using different names for fixture and test parameter

Incorrect length assertion

The fixture and test parameter are both named fruits. The list has 3 items, so the length is 3.
