Look there to find the complete statement. For 3.1, it would be

self.assertRaises(urllib.error.URLError,
                                   h.file_open, Request(url))
(urllib2 is now urllib.request)

You could insert a print to find what url caused a problem.

This puzzles me. In 3.1, unittest is a module, unittest.py, not a 
package containing modules like 'case.py'. I though it was the same for 2.7

This is in unittest.py. It says that this test case *should* fail, but 
with a different error (urllib.error.URLError) than the one you got 
(gaierror).

gaierror comes from socket.gethostbyname

Since error is in open_local_file, I would think not.
