@pytest.mark.skip with reason - Test Execution Trace

Test Overview

This test demonstrates how to skip a test in pytest with a clear reason. It verifies that the test is not executed and is reported as skipped.

Test Code - pytest

PyTest

import pytest

@pytest.mark.skip(reason="Skipping this test because feature is under development")
def test_feature_under_development():
    assert False, "This should not run"


def test_always_passes():
    assert True

Execution Trace - 4 Steps

Step	Action	System State	Assertion	Result
1	Pytest starts test run	Test suite loaded with two tests: one skipped, one normal	-	PASS
2	Pytest identifies test_feature_under_development is marked with @pytest.mark.skip	Test runner skips execution of test_feature_under_development	Test is skipped with reason 'Skipping this test because feature is under development'	PASS
3	Pytest executes test_always_passes normally	Test runs and completes without errors	Assert True passes	PASS
4	Pytest finishes test run and reports results	Test report shows one skipped test with reason and one passed test	Skipped test reason is displayed in report	PASS

Failure Scenario

Failing Condition: If the skip decorator is removed or reason is missing, the test runs and fails due to assertion

Execution Trace Quiz - 3 Questions

What happens to a test marked with @pytest.mark.skip(reason="...")?

A The test runs and always passes

B The test runs but ignores assertions

C The test is not run and is reported as skipped with the given reason

D The test runs and always fails

Key Result

Use @pytest.mark.skip with a clear reason to document why a test is skipped. This helps others understand the test status and keeps test reports informative.
