Hi there, I also started observable unit testing with this blog.
At first it seems pretty easy, but marbles can get very tricky when the use case is more advanced..
I recommend to use HiRez's observerSpy..
github.com/hirezio/observer-spy

You can then just test the outcome, without setting up the marbles :)
