A nice clean test run

o All tests running and passing with 56% coverage.
o Eliminated all warning messages. Had to add a check to only run commands if needed files and dirs exist.
  If they don't, we'll soon throw exceptions to drive out more bugs.
o Have some exceptions in place that will help drive out more test bugs.
o Removed straggler test file from before.
