Add Tests

[rwieruch]

The library is not extensively tested. It only tested Redux logic and helper logic, but none of the components (src/components/) or higher order components (src/enhancements/). It would be great to add tests for these.

Any opinions on adding Jest over mocha? Would also simplify the coverage story with instanbul and codecov. Maybe easier to swap the test runner early. I could jump in and help a bit...

Hey @tdeekens We have no hard feelings for the test framework. It would be okay to exchange Mocha with Jest. At least all tests would need to be moved over, but as well it would be great to add more of them :)
