How do you correctly define a pytest fixture that runs automatically before each test without needing to be explicitly used?
A@pytest.fixture() def setup(autouse=True): pass
B@pytest.fixture(autouse=True) def setup(): pass
C@pytest.autouse def setup(): pass
D@pytest.fixture(autouse=False) def setup(): pass
Step-by-Step Solution
Solution:

  1. Step 1: Identify correct decorator usage

    The autouse parameter is passed inside @pytest.fixture().

  2. Step 2: Check syntax correctness

    @pytest.fixture(autouse=True) def setup(): pass correctly uses @pytest.fixture(autouse=True) before the fixture function.

  3. Final Answer:

    @pytest.fixture(autouse=True) def setup(): pass -> Option B

  4. Quick Check:

    Autouse is a parameter inside @pytest.fixture [OK]
Quick Trick: Use autouse=True inside @pytest.fixture decorator [OK]
Common Mistakes:
MISTAKES
  • Placing autouse as a function argument
  • Using @pytest.autouse decorator which does not exist
  • Setting autouse=False expecting automatic execution
