Run xsdata code generator and data binding modules against the W3C XML Schema 1.1 test suite.
The invalid schema tests are ignored (~12k tests) as xsdata is not really a validator.
Each test case will generate the models for the schema document, parse the xml instance document and serialize it back to xml checking that the output is still valid.
$ pytest -n 4 --mode xsd --runxfail --save-output
Results: 5 failed, 14580 passed, 89 skipped, 16 warnings
The save output option will store the output xml document. The xml mode's drawback is that it doesn't do any quality checks that all elements and values actually match the original document.
