CTo mark a test as expected to fail
DTo group multiple test functions into a test suite
Step-by-Step Solution
Solution:

  1. Step 1: Understand the decorator's role

    @pytest.mark.parametrize allows running one test function multiple times with different inputs.

    Only To run the same test function multiple times with different input values describes running the same test with different inputs, matching the decorator's purpose.

  3. Final Answer:

    To run the same test function multiple times with different input values -> Option B

  4. Quick Check:

    Parametrize = multiple inputs [OK]
Quick Trick: Parametrize means run test many times with different data [OK]
