+- unittest-style ``setUp, tearDown, setUpClass, tearDownClass`` 
+  are recognized only on ``unittest.TestCase`` classes but not
+  on plain classes.  ``nose`` supports these methods also on plain
+  classes but pytest deliberately does not.  As nose and pytest already 
+  both support ``setup_class, teardown_class, setup_method, teardown_method``
+  it doesn't seem useful to duplicate the unittest-API like nose does.
