I applied some changes to the tests. I verified locally that these tests are skipped on Windows when Developer Mode is disabled, and they pass on Windows when Developer Mode is enabled. This looks good to me.

@b-butler @cbkerr @joaander if you have feedback, feel free to weigh in -- otherwise I think this is good to merge.

[joaander]

Thanks @slowglow and @bdice! The change is reasonable to allow functionality previously not allowed and the unit tests are updated appropriately.

FYI, CI looks blocked (perhaps due to #957) because the expected checks are changing.

I removed the 3.12 required checks for now. #957 appears to have some issues with pandas that may take some time to resolve.

Thank you!
