+
+Support for Python test results in xUnit format is experimental - should work but it was not extensively tested.
+
+For pytest support, configure [JUnit XML output](https://docs.pytest.org/en/stable/how-to/output.html#creating-junitxml-format-files) and run with the `--junit-xml` option, which also lets you specify the output path for test results.
+
+For unittest support, use a test runner that outputs the JUnit report format, such as [unittest-xml-reporting](https://pypi.org/project/unittest-xml-reporting/).
