Coverage, and more changes.

I omitted the tests folder from considered in the test coverage.  It drops down to 71%.  I might spend the next 30 minutes to bring that up a bit but I don't want to expend too much more effort.  I have enough functionality being covered off for adding more.

Bringing app2.py might be wise.

With some mocking, (thanks unittest.mock's patch), The coverage is up to 82% as shown below.  I learned a lot with being able to call directly into my Flask application.  This is a good reason to celebrate!
