I am trying to write some tests for sequencek

"mapFilter" {
      forAll(Gen.choose(1, 10000)) { n: Int ->
        val op: SequenceK<Int> = List(n) { s: Int -> n * s }.asSequence().k()
        val res = List(n) { s: Int -> n * s }.foldLeft(emptySequence<Int>())
        { acc, i -> if (i < 22) acc else acc + i }.k()
        op.mapFilter { if (it < 22) None else Some(it) } == res
      }
    }
