TCK support for restricted length Producers and Consumers about reactive-streams-jvm

[ktoso]

Thanks for the feedback Rich,
the use case would be like an FromFuturePublisher, so it only can send up to 1 element, right?

We'll try to figure something out, may be easy enough to integrate your request.

Yes, my use case is single-element publishers and consumers made by wrapping Scala's futures and promises. I can also imagine zero-element versions of publishers and consumers (Publisher.empty, Consumer.empty) and versions of publishers and consumers that can only handle finite lengths (Publisher.fromArray, Consumer.toArray).

[ktoso]

So my current suggestion would be (as seen in PR #91):

  @Override 
  public long maxElementsFromPublisher() { return 1; }

Which skips all tests which require more than 1 element to run (so currently, most of them: Total tests run: 18, Failures: 0, Skips: 13 (publisher specs)). The skip message includes this as the reason. Opinions about this way of exposing publisher capabilities?

Looks like it was solved to me. Closing.
