Is there a way to run tests with androidx.compose.ui.test visible (so that I can see them)? I’m having trouble with something and it would help to be able to see the UI as the test is trying to execute.

We don’t have a public API for that at the moment, but you can grab the source of our internal test API from androidx.compose.ui.window.TestUtils and use that.

[Alexander Maryanovsky]

It’s a very bare-bones API though - it doesn’t have the event dispatching or node-finding APIs.

Thank you very much. I’ll check that out 👍

[Marc Fearby]

Where can I get the source for this? Is it publicly accessible or only for internal JetBrains use? I can’t seem to find it via Google anywhere.

[Alexander Maryanovsky]

Turns out I was wrong and, as I think you found, we do have an experimental testing API.

I have same question.

Could you clarify how androidx.compose.ui.window.TestUtils can be used to show the window? will be even more happy for an example.

Currently I have something like this

class FilePickTest {

	@get:Rule
	val rule = createComposeRule()

	@Test
	fun blah() {
		rule.setContent {
			Button(onClick = {
				println("button clicked")
			}) {
				Text("print stuff")
			}
		}

		rule.onNodeWithText("print stuff").performClick()
		runBlocking { delay(5_000) }
	}
}

I'd like to see the button and if possible interact with it

[Alexander Maryanovsky]

You can’t. The test API draws into an offscreen buffer. There’s no actual window involved.
