FAIL: test_resolve_common (test.test_pathlib.PathTest)
----------------------------------------------------------------------
======================================================================
The problem is that the temporary directory path returned by tempfile.mkdtemp() contains the username in "short" (8.3) format, but Path.resolve() converts short names to long ones (thanks to ntpath._getfinalpathname()).
Since os.path.realpath() still doesn't resolve symlinks on Windows (bpo-9949, bpo-14094), and users of ntpath._getfinalpathname() have to deal with '\\?\' prefix, I think I'll just use Path.resolve() for the tmp dir path as a workaround.
