According to the logs, node.text is null in the assertion here (which is why it cannot be cast to a String):

        mainSession.finder.find("Hell", 0)
        sessionRule.waitUntilCalled(object : EventDelegate {
            @AssertCalled(count = 1)
            override fun onAccessibilityFocused(event: AccessibilityEvent) {
                val node = createNodeInfo(getSourceId(event))
                assertThat("Text node should match text", node.text as String, equalTo("Hello "))
            }   
        })

But that try-run has two runs of gv-unit, one succeeding with the exact same log (aside from the exception and timestamps/ids, of course):

(failing run, succeeding run).

So it looks like the wrong node is being selected (one without any text) when the test de-focuses the find UI. And it looks like that's what the bug this test was added for is trying to account for (bug 1615562) in the first place.

eeejay, based on the patch you wrote for that bug I have to wonder which node the caret jumps to which has no text, given that based on that patch it's supposed to be an ancestor node which is focusable, and this is the entire HTML:

<p>Hello <a href='foo'>sweet</a>, sweet <span>world</span>

Any thoughts?

Hi Thomas,

The paragraph and the document nodes both don't have a "text" fields, I believe.

My bet is that there is an intermediate accessibility focused event that sometimes happens when the caret collapses from the previous selection, the caret then is maybe set to 0 and the document is focused.

Might be worth adding a step before that test and reset the caret to the start and wait for the focus:

        // reset caret position
        mainSession.evaluateJS("""
            this.select(document.body, 0, 0);
        """.trimIndent())
        sessionRule.waitUntilCalled(object : EventDelegate {
            @AssertCalled(count = 1)
            override fun onFocused(event: AccessibilityEvent) {}
        })

Also, if that last check is removed I think our coverage is still good.
