is short for marble testing

RxJS 6 offers great testing features as you can find here.

However I found it confusing how to get started with this but then this post was helpful for me to understand and get started.

And I made this gist and now I created this as npm package because why not.

$ yarn add --dev marblet

Checkout tests. It's both tests and examples.

I used Jest for testing in there but it should have no problems being used with any testing framework.
