/* Implementation note: In JUnitTask we use Future[Try[Unit]] instead of simply
 * Future[Unit]. This is to prevent Scala's Future implementation to box/wrap
 * fatal errors (most importantly AssertionError) in ExecutionExceptions. We
 * need to prevent the wrapping in order to hide the fact that we use async
 * under the hood and stay consistent with JVM JUnit.
