Comment (by joshuacookebarnes@…):

 Ok, I've managed to get tests to pass, with a few patches, mainly to fix
 broken `import` statements.

 However, I also needed to patch a broken atexit function in
 `pyvisa.legacy.visa`, which was trying to use a `resource_manager` which
 turned out to be `None` at call. I'm not completely sure that this doesn't
 simply hide a broken test, rather than just get the test to run correctly.

 Finally, the tests will only pass if the location of the visa shared
 library is set by a `~/.pyvisarc` file.
 It might be worth patching to look for the library in the default Darwin
 install location (`/Library/Frameworks/VISA.framework/VISA`), but I
 haven't bothered so far.
