Tests missing in hex.pm package

[htgoebel]

When fetching the package from hex.pm, the tests are missing. Thus one can not check whether the package is actually working (passing tests) in the own environment.

Please add the tests to the hex.pm package (and publch a new version ;-). Thanks.

The tests won't give you good results, since they're tests that willingly break and fail so that I can manually check the output that results. I willingly did not check them in because they're not meant to pass.

I never found a good enough solid way to deal with things such as color, suppressed output, and so on, for a test suite while running the test suite itself and just left it manual since I update this lib once every couple of years.
