+

+
+        - Instance methods:
+
+            - `self.set_up()`: subclasses should use this for their

+
+            - `self.tear_down()`: subclasses should use this for their
+              test-by-test tear down
+
+        - Classmethods:
+
+            - `cls.set_up_class():`:  subclasses should use this for their
+              class-level set up
+
+            - `cls.tear_down_class()`: subclasses should use this for their
+              class-level tear down

+
+            - If you call any snake_case method call (instance method or
+              classmethod) and that method does not exist, BaseTestCase will 
+              attempt to call the mixedCase version, e.g.:
+                - `self.assert_equal()`:  aliases self.assertEqual
+                - `self.assert_true()`:  aliases self.assertTrue
