Add tests
It was brought up somewhere else that we should have test cases for this. And I agree. I just started to discover TAP and this seems that could help: CI - travis-ci Integration test - https://github.com/sstephenson/bats Lint - https://github.com/openstack-dev/bashate https://github.com/koalaman/shellcheck
Nice find, ideally we should also look into making most functions pure then. Lots of global variables still in play sadly.
