Unit Testing Integration with Travis or Circle CI

[josev814]

It would be nice to have Unit Tests developed for the purpose of ensuring that when PRs are done that the PR doesn't break any of the features already available in the package.

Unit Tests could be created and then use Travis-CI or Circle-CI to run the unit tests prior to allowing a PR to be merged.

It looks like others have worked on getting a robot test running in Circle CI, so it should be possible to have UT's run for this plugin.
