Each test results in an AttributeError: 'dict' object has no attribute 'motif' (or very similar). Motif classes do not appear to be included with the install.
Error was caused by same-named 'dict' objects in an older version of pymfinder. Turns out the Mac isn't smart enough to flag that on installation, but removing the old version corrected the error. Tests now run.
