1. Move `clean_before_test` to the first test so its more explicit.
2. Move `skip_not_tar_gz` to setup because it was run first in every test.
3. Remove calls to `run` that only check the status. Its simpler to just
execute the command. Its better because std-out will be captured and replayed
on error.
4. Switch from `su` to `sudo` because `su` was breaking `bats`'s error
reporting.
In the bats test ES_CLEAN_BEFORE_TEST was used to clean the environment
before running the tests. Unfortunately the tests don't work unless you
specify it every time. This removes that option and always runs the clean.
This creates a module in qa called vagrant that can be run if you have
vagrant and virtualbox installed and will run the packaging tests in trusty
and centos-7.0. You can ask it to run tests in other linuxes. This is the full
list:
* precise aka Ubuntu 12.04
* trusty aka Ubuntu 14.04
* vivid aka Ubuntun 15.04
* wheezy aka Debian 7, the current debian oldstable distribution
* jessie aka Debian 8, the current debina stable distribution
* centos-6
* centos-7
* fedora-22
* oel-7
There is lots of documentation on how to do this in the TESTING.asciidoc.
