After installing the latest py.test and the pytest-cov plugin using pip
I ran the following command in my hg Roundup source repository dir::

  py.test --cov=.

The output of this test run is attached as roundup_coverage_report.txt

My proposal is that we developers try to increase the test coverage
on the roundup code base over time.  
This is an engineering task which will not be easy.  
But I believe it will pay off in the end.  
I create this general issue here now so we have one to refer to in
commit messages.
