If you start writing tests and you reach for JujuConnSuite, stop.  You
should be able to get to 80% code coverage (and near 100% logic coverage)
without using anything outside your package.  Just provide some stub
implementations of interfaces and assert that the logic run against those
interfaces is correct.  If you have too many dependencies on code outside
your package, start writing interfaces and refactor your code to use them
instead of explicitly relying on external types.
