A@pytest.fixture def greeting(): print('hello')
Bdef greeting(): return 'hello' @pytest.fixture
Cimport pytest def greeting(): return 'hello' @pytest.fixture()
Dimport pytest @pytest.fixture def greeting(): return 'hello'
Step-by-Step Solution
Solution:

  1. Step 1: Import pytest

    Fixtures require the pytest.fixture decorator, so importing pytest is necessary.

  2. Step 2: Define the fixture function with the decorator

    The function must be decorated with @pytest.fixture before its definition.

  3. Step 3: Return the desired value

    The fixture should return the string value as intended.

  4. Final Answer:

    Function decorated with @pytest.fixture and returns string -> Option D

  5. Quick Check:

    Decorator before function and proper import [OK]
Quick Trick: Always decorate fixture functions with @pytest.fixture [OK]
Common Mistakes:
MISTAKES
  • Placing @pytest.fixture after the function
  • Not importing pytest before using the decorator
