TableDrivenPropertyChecks + AsyncWordSpecLike not working when used together

[camilosampedro]

Version of scalatest: 3.0.9

When you try to create tests like:

class DummyTest extends AsyncWordSpecLike with TableDrivenPropertyChecks {
  "DummyExample" should {
    val cases = Table(
      ("foo", "bar"),
      (0, 1)
    )
    "be ok" in forAll(cases) { (foo, bar) =>
      val result: Future[Assertion] = Future {
        assert("a" == "a")
      }
      result
    } // <- forAll returns Unit, which is not the `Future[Assertion]` that Async tests expect
  }
}

The result expected by the async in {...} is Future[Assertion], but forAll returns Unit.

Is there a way to use both of them together?

Looks like there might be some discussion about this here, but not a lot of action there either...

Thank you @ionsquare

For reference, in case anyone is having the same issue and wants a workaround, you can use org.scalatest.wordspec.AnyWordSpecLike with org.scalatest.prop.TableDrivenPropertyChecks and org.scalatest.concurrent.ScalaFutures mix-ins and it will let you do .futureValue.

Just to oversimplify it:

val table: TableFor1[BigDecimal] = ???
val futureOperation: BigDecimal => Future[BigDecimal] = ???

"my test" should {
  "pass" in forAll(table) { foo =>
    futureOperation(foo).futureValue shouldBe 300
  }
}
