Is it impossible to do what I want, or am I thinking of the wrong word

[hitmanb...@gmail.com]

I am working with scala-js, and I am trying to write a WordSpec test for the very first thing that runs, setting up the ui. Currently I have

  "An HTML Document" when {
    "setupUI() is called" should {
      "contain a style element" in {
        assert(jQuery("style").length >= 1)
      }
    }
  }

This is great, however, I also want to make sure that said style element has its "id" field set properly. What I would think to do is

"An HTML Document" when {
    "setupUI() is called" should {
      "contain a style element" in {
        assert(jQuery("style").length >= 1)
      }
      which should "have its id set" in {
        assert(!jQuery("style")(0).id.isEmpty())
      }
    }
  }

The problem is that there is no "which" keyword.  

What is the proper way to do something like this? It almost seems like I should have another when>should>in block for the style element, but that seems redundant.
