 A typical ``load_tests`` function that loads tests from a specific set of
 :class:`TestCase` classes may look like::
 
-    test_cases = (TestCase1, TestCase2, TestCase3)
-
     def load_tests(loader, tests, pattern):
         suite = TestSuite()

+This could be used to load a set of tests that are dynamically generated to

 If discovery is started in a directory containing a package, either from the
 command line or by calling :meth:`TestLoader.discover`, then the package
 :file:`__init__.py` will be checked for ``load_tests``.  If that function does
