How to perform unit test for Binding.Scala?

Question

I had written components using Binding.scala and they're working fine for me. Now I want to unit test them using ScalaTest. How to unit test them?

I had taken reference from Binding.scala's unit tests. However it's not working for me as get and valuemethods are not accessible.

In current version of Binding.scala (11.8.1) you can use this method for unit testing:

  "Comment" in {
    @dom def comment = <div><!--my comment--></div>
    val div = document.createElement("div")
    dom.render(div, comment)
    assert(div.innerHTML == "<div><!--my comment--></div>")
  }

Unfortunately, you couldn't write such (more performant?) tests:

  "TextElement" in {
    @dom val monadicDiv: Binding[Div] = <div>text</div>
    monadicDiv.watch()
    assert(monadicDiv.get.outerHTML == "<div>text</div>")
  }

because of Binding.get/Binding.value is private/protected. I filled issue about this https://github.com/ThoughtWorksInc/Binding.scala/issues/217
