Asynchronous Prop

[lukiano]

This is a feature request for a Prop whose apply method has the signature
def apply(prms: Parameters): Future[Result]

And the necessary modifications in methods like Test.check and Prop.forAll

Coupling this with a Test framework that accepts Futures, like ScalaTest 3, would give us the ability to test Futures in ScalaJS where there is no Await.result()

I'm also very interested in this -- we need it for Scala.js testing in https://github.com/functional-streams-for-scala/fs2.

Would be nice to have some kind of AsyncScalaCheckPropertyChecks that plays well with AsyncFlatSpec of scalatest.

[akilegaspi]

Has there been any consideration for doing this?

This is now supported by a companion project: https://github.com/typelevel/scalacheck-effect

I always thought it was coupled to cats-effect, but it even works with MonadError, so even the original request for Future should be covered.
