[Solved] Identify the error in this pytest fixture code for a Flask app:@pytest.fixture def client(): app = Flask(__name__) client = app.test_client() return client print('Cleanup done') | Flask

Flask - Testing Flask Applications

Identify the error in this pytest fixture code for a Flask app:

@pytest.fixture
def client():
    app = Flask(__name__)
    client = app.test_client()
    return client
    print('Cleanup done')

AFixture must use 'yield' instead of 'return' always

BMissing '@pytest.fixture' decorator

C'app.test_client()' is not a valid method

DThe 'print' statement after 'return' will never execute

Step-by-Step Solution

Solution:

Step 1: Check code after return statement
Code after 'return' is unreachable, so 'print' will never run.
Step 2: Confirm other parts are correct
The decorator is present, 'app.test_client()' is valid, and 'return' is allowed but limits cleanup.
Final Answer:
The 'print' statement after 'return' will never execute -> Option D
Quick Check:
Code after return is unreachable [OK]

Quick Trick: Code after return is ignored; use yield for cleanup [OK]
