@SRserves85 @irux @chasdevs Please let me know if this makes sense so I could add the tests for the case.

[isenilov]

Thank you @chasdevs ! I guess you also need to approve the workflow if it is ok to merge.

[chasdevs]

No problem; would you mind adding a quick test before the merge? If it's an emergency I can approve but want to keep that coverage high.

[isenilov]

Added examples for map in union to the test data. There is still one test that is failing but it seems like it is not related to my changes: FAILED tests/test_paths.py::PathTests::test_get_system_file_path - AssertionError: '/tmp/avro/nest/test2.avsc' != '/private/tmp/avro/nest/test2.avsc' Might be my machine though, I am running on Mac

[chasdevs]

Hmm let me try that out rq. Thanks for adding the test data!

[chasdevs]

Yeah not your branch. Approving! If it fails on that one test we can still merge it in.

[isenilov]

Seems like it works!
