-            def test_compile(self):
-                copy_xxmodule_c(self.tmpdir)
-                self.assertIn('xxmodule.c', os.listdir(self.tmpdir)

     If the source file can be found, it will be copied to *directory*.  If not,
     the test will be skipped.  Errors during copy are not caught.
