+Exceptions
+----------
+
+Exceptions raised by views or other code while handling a request made by
+``Client`` will bubble up to your test case. The default test runner,
+``django.test.simple.run_tests`` will print a stack trace for an unhandled
+exception. ``unittest.TestCase``'s ``assertRaises`` method can be used to test
+that exceptions are raised by views, which can be useful to test error
+handling. You may also catch exceptions in the normal way and inspect them in
+your test code.
+
+``Http404``, ``PermissionDenied`` and ``SystemExit`` are caught by Django's
+base handler. These exceptions will not make it back to your test if raised
+during a request.
