Identifying missing test case classes

The balance of the testing goals noted earlier all require the ability to examine the code being tested in order to identify module members, and members of those members, that need to be tested. This might sound daunting, but Python provides a module dedicated to that purpose: inspect. It provides a very robust collection of functions that can be used to examine Python code at runtime, which can be leveraged to generate collections of member names that can, in turn, be used to determine whether the high-level test coverage meets the standard we're establishing.

For the purposes of illustration, the preceding classes that we need to test will be saved in a module called, which makes them importable, ...
