No timeout for tests returning Future[Assertion]

[Joaquin]

Hi all,

Thank you for the great work on Scalatest.

I recently discovered that, with AsyncFunSpec, when a test finishes
with a Future[Assertion], Scalatest will actually wait for the future
to complete to ensure that it is successful and the assertion
truthful.

Unfortunately I haven't found a way to only wait for a limited time,
which has the potential to make tests hang forever. PatienceConfig,
which works with whenReady, seems not to be taken into account here:

it("Unfortunately, PatienceConfig doesn't seem to be taken into
account when waiting for the returned Future[Assertion]"){
implicit val patienceConfig: PatienceConfig = PatienceConfig(
timeout = scaled(Span(5, Seconds)),
interval = scaled(Span(100, Millis))
)

Future[Int]{
Thread.sleep(1000 * 1000)
3
}.map(_ shouldBe 4)
}

The code above in context:

Is this by design? A possible future feature?

Best regards,
