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.

We can't see why it's not working if you don't share your "not working" code/tests... — James Whiteley, Sep 25 '19 at 15:03
Ops! It's really not possible to write such test in the user code: ``` "TextElement" in { @dom val monadicDiv: Binding[Div] =
text
monadicDiv.watch() assert(monadicDiv.get.outerHTML == "
text
") } ``` because `Binding.get`/`Binding.value` is private/protected :( — lmars, Sep 26 '19 at 04:40

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

In the new [html.scala](https://github.com/GlasslabGames/html.scala), there is a `NodeBinding` type, which has a public `value` to access the raw HTML object. See https://github.com/GlasslabGames/html.scala#getting-started — Yang Bo, Nov 03 '21 at 04:51
