+
+Skipping tests and expected failures
+------------------------------------
+
+Unittest supports skipping individual test methods and even whole classes of
+tests.  In addition, it supports marking a test as a "expected failure," a test
+that is broken and will fail, but shouldn't be counted as a failure on a
+:class:`TestResult`.
+
+Skipping a test is simply a matter of using the :func:`skip` :term:`decorator`
+or one of its conditional variants.
+
+Basic skipping looks like this: ::
+
+   class MyTestCase(unittest.TestCase):
+
+       @unittest.skip("demonstrating skipping")
+       def test_nothing(self):
+           self.fail("shouldn't happen")
+
+This is the output of running the example above in verbose mode: ::
+
+   test_nothing (__main__.MyTestCase) ... skipped 'demonstrating skipping'
+
+   ----------------------------------------------------------------------
+   Ran 1 test in 0.072s
+
+Classes can be skipped just like methods: ::
+
+   @skip("showing class skipping")
+   class MySkippedTestCase(unittest.TestCase):
+       def test_not_run(self):
+           pass
+
+Expected failures use the :func:`expectedFailure` decorator. ::
+
+   class ExpectedFailureTestCase(unittest.TestCase):
+       @unittest.expectedFailure
+       def test_fail(self):
+           self.assertEqual(1, 0, "broken")
+
+It's easy to roll your own skipping decorators by making a decorator that calls
+:func:`skip` on the test when it wants it to be skipped.  This decorator skips
+the test unless the passed object has a certain attribute: ::
+
+   def skipUnlessHasattr(obj, attr):
+       if hasattr(obj, attr):
+           return lambda func: func
+       return unittest.skip("{0!r} doesn't have {1!r}".format(obj, attr))
+
+The following decorators implement test skipping and expected failures:
+
+.. function:: skip(reason)
+
+   Unconditionally skip the decorated test.  *reason* should describe why the
+   test is being skipped.
+
+.. function:: skipIf(condition, reason)
+
+   Skip the decorated test if *condition* is true.
+
+.. function:: skipUnless(condition, reason)
+
+   Skip the decoratored test unless *condition* is true.
+
+.. function:: expectedFailure
+
+   Mark the test as an expected failure.  If the test fails when run, the test
+   is not counted as a failure.
