PyTest - Parametrize
Why is it important to use pytest.param with marks=pytest.mark.skipif instead of skipping tests inside the test body when using parameterized tests?
ABecause skipping inside test body runs the test and wastes time
BBecause pytest.param is required for all tests
CBecause skipping inside test body causes syntax errors
DBecause pytest does not support skipping tests

    Skipping inside test body means the test starts running before skip is called.

  2. Step 2: Benefits of skipping in parametrize

    Using pytest.param with skipif skips the test before running, saving time and resources.

  3. Final Answer:

    Because skipping inside test body runs the test and wastes time -> Option A

  4. Quick Check:

    Skip early with pytest.param to avoid running skipped tests [OK]
Quick Trick: Skip tests early with pytest.param to save time [OK]
