how to assert on exception thrown from CompletableFuture<T> ?

[Sourabh Rawat]

following will work:

val dbException = shouldThrow<DynamoDbException> {
        dataRepository.getEventsForBucketId(getEventIdsForBucketIdRequest).await()
      }

There's also, future.shouldBeCompletedExceptionally()

but that doesnt return the exception as far as I know.
