Is your feature request related to a problem? Please describe.
Coveralls shows that the special Windows file comparison tests for SuperMAG and vorticity data are not being run, but nothing is failing in the Windows CI tests.
Describe the solution you'd like
Only have necessary lines of code in the unit tests.
Describe alternatives you've considered
Leaving things as they are.
Additional context
In the past, the AppVeyor system setup for earlier versions of Python didn't support filecmp. However, things improve and it might be possible to use it now.
