Tests for core libraries

Create tests for core libraries

Can we setup a testing framework (Jest comes to mind, but it can be anything) for the core libraries for components. The tests don't need to be rigorous, but before a PR is accepted, we can insist that the some sort of testing be done. Now I do realize that this project is in Beta, and so again, I am not proposing that we rigorously test things, just setup the framework and provide a modicum of tests that will guide anyone who wishes to contribute.

Absolutely! We're doing couple of experiments that might change the API, but once this is set in stone, we'll def add tests.

Best if they're setup with help of serverless/test (proven to be bulletproof, and already some other serverless projects rely on this)
