reverse

✓ pytest.mark.reverse

No direct import needed. Use the --reverse CLI flag or @pytest.mark.reverse() mark.

Use --reverse flag to reverse entire test session, or @pytest.mark.reverse() marker to reverse only specific tests.

# Run all tests in reverse order pytest --reverse # Reverse a single test with marker import pytest @pytest.mark.reverse() def test_one(): assert True def test_two(): assert True

Debug

Known issues

gotchaThe --reverse flag reverses the order of tests within each scope (module, class, function). It does NOT reverse the order of test files unless combined with other plugins.

fix

To reverse test file order, use pytest --reverse --co (with pytest-order plugin) or sort test files manually.

affects: all

gotchaUsing @pytest.mark.reverse() at the class level reverses tests within that class, but does not reverse tests outside the class.

fix

Apply marker to each test function you want reversed, or use --reverse for global reversal.

affects: all

deprecatedThe pytest.mark.reverse marker without parentheses (e.g., @pytest.mark.reverse) is deprecated since version 1.7.0 and will be removed in a future release.

fix

Use @pytest.mark.reverse() with parentheses.

affects: >=1.7.0
