Adding tests

[jevakallio]

Hi @fossage! I've added jest to the project, but am currently struggling finding time to contribute. Tests are more than welcome!

However please be aware that some breaking changes are coming soon, so any tests for createOfflineStore are not necessary.

[fossage]

@jevakallio , okay great. I'll start putting some together and hopefully have a PR ready in the near future. Aside from Jest, do you have any other testing utilities you prefer and/or want to avoid? Lately I've been using a combination of jest and redux-mock-store for reducer testing which seems to be working pretty well.

@fossage redux-mock-store is great! I hadn't decided if I wanted to run store reducer tests as snapshot tests or regular chai assertions - either is fine.

[fossage]

@jevakallio , Cool yea I'm ambivalent on snapshots as well so I'll try to keep them to a minimum. Do you want the tests to be set up to run on any Git hooks?

[jevakallio]

@fossage let's set up any git hooks separately if necessary I'd generally prefer to run the tests on Travis, so hooks may be overkill.
