 There are several possible strategies available for dealing with dangling
 mock objects (see the section on recommended patterns).

 Dangling Mock Detector
 ----------------------
 
 All Trove unit tests should extend 'trove_testtools.TestCase'.
 It is a subclass of 'testtools.TestCase' which automatically checks for
-dangling mock objects after each test.
-It does that by recording mock instances in loaded modules before and after
-a test case. It marks the test as failed and reports the leaked reference if it

 Recommended Mocking Patterns
 ----------------------------
 
-- Mocking a class or object shared across multiple test cases.
-  Use the patcher pattern in conjunction with the setUp() and tearDown()
-  methods [ see section 26.4.3.5. of [1]_ ].
