medium📝 Debug Q6 of 15
Selenium Python - Test Framework Integration (pytest)
Identify the error in this parameterized test code:
@pytest.mark.parametrize('num', [1, 2, 3])
def test_is_even(num):
    assert num % 2 == 0
ASyntax error due to missing colon after function definition
BTest will fail for odd numbers but code has no syntax error
CDecorator is misspelled causing runtime error
DParameter list should be a tuple, not a list
Step-by-Step Solution
Solution:
  1. Step 1: Check syntax correctness

    The code syntax is correct; decorator and function are properly defined.
  2. Step 2: Analyze assertion logic

    Test asserts number is even; 1 and 3 are odd, so tests will fail for those inputs.
  3. Final Answer:

    Test will fail for odd numbers but code has no syntax error -> Option B
  4. Quick Check:

    Logical failure, no syntax error [OK]
Quick Trick: Syntax correct but logic causes test failures [OK]
Common Mistakes:
  • Thinking missing colon causes error
  • Assuming decorator spelling is wrong
  • Believing lists cannot be used for parameters
