Regression Test Precision#

Regression tests use percentage-based relative tolerances (rtol) for numerical comparison:

  • High precision (rtol=1e-6 = 0.0001%): Efficiency analysis, load sweep, wrapper parity

  • Medium precision (rtol=1e-3 = 0.1%): RXC filter values

  • Lower precision (rtol=1e-2 = 1%): LCR fitting parameters, R² values

Relative tolerance means the allowed difference is proportional to the magnitude of the values being compared.

Windows Compatibility#

LCR fitting tests are @pytest.mark.xfail on Windows due to numerical precision differences in optimization algorithms. This is expected behavior.

@pytest.mark.xfail(
    condition=sys.platform == "win32",
    reason="LCR fitting results differ significantly on Windows due to numerical precision differences",
    strict=False,
)

Archive System#

Tests use binary pickle archives (tests/data/analysis_regression_results.pkl) for precise numerical comparison with automatic creation and updates.

Coverage Reports#

Excluded Files#

Files excluded from coverage analysis are listed in pyproject.toml:

[tool.coverage.run]
omit = ["wpt_tools/plotter.py"]

Viewing Coverage#

  • Terminal: uv run pytest tests/ --cov=wpt_tools --cov-report=term-missing

  • Direct: uv run coverage report --show-missing

Excluded files are not shown in coverage reports.
