Find multiple elements in web view with espresso

Question

I'm testing a hybrid app, where each view has a web view.
In one of these web views I have a list of elements with the same attribute. They have the same xpath locator that is something like:

//h4[contains(@data-role, 'product-name')]

I want to create a list of these elements and iterate through them, count them, get their attributes.

In the documentation, I found two similar methods:

findElement(locator, value)

and

findMultipleElements(locator, value)

Though it's totally unclear to me how to use it. I tried to find examples on it but with no success.

Could someone help me with this?

Here is the solution that I have found.

@kaqqao is right that findMultipleItems call returns Atom<List<ElementReference>> that is not usable with onWebView() because there you have only withElement() that accepts either Atom<ElementReference> or just ElementReference

What you can do though is perform your action that find multiple items and just get results from your Atom. This is how it works internally if you check the source of doEval method inside Web.java for espresso.

val elements = with(AtomAction(findMultipleElements(
                Locator.XPATH,
                "YOUR_COMPLEX_XPATH"
        ), null, null)) {
            onView(ViewMatchers.isAssignableFrom(WebView::class.java)).perform(this)
            this.get()
        }

This code will give you List<ElementMatcher>.

Then just run it as

elements.forEach {          
  onWebView().forceJavascriptEnabled().withElement(it).perform(webClick())
}
