Support Time progression syntax

See original GitHub issue

I couldn’t get the following marble to run with jest-marbles, but it worked fine with the normal testScheduler setup. Cold and hot just give me frames for every letter/digit.

// standard rxjs setup
expectObservable(obs).toBe(' 5000ms b')

// jest-marbles
cold(' 5000ms b')
hot(' 5000ms b')

I hope that’s enough info to reproduce.

npm info = jest-marbles@2.3.1

Ok, the issue is identified. jest-marbles use TestScheduler in the old way (outside of run method). Time progression syntax is not supported in this way.
I’ll issue a new major version that uses run method but most likely it will take some time because the documentation has to be aligned and there are syntax differences between the two ways.
How urgent is this for you?

I’ll look into this.
