Difference Between pytest’s skip, skipif, & xfail Markers

Sometimes we may want to skip some tests because either 1) the functionality they test is not supported yet Or 2) some versions of the library didn’t support it. We can use one of the following three pytest markers for this purpose:

• pytest.mark.skip: Skip the test completely
• pytest.mark.skipif(condition, ...): Skip the test if the condition is True
• pytest.mark.xfail(..., strict=False): Run the test even though we know it would fail. The strict option determines if the passed test is classified as XPASSED if strict=False OR FAILED if strict=True. If the test failed, it would always return XFAIL regardless of the strict option.
