I’m trying to write some really basic UI tests with dev07's test library (`findByText` and friends), but even really simple assertions fail unexpectedly. Are there any limitations around what the semantics/testing infra can handle? More in thread.

This test, for example, tries to just assert some static text is displayed, to verify the app launched, but if you uncomment the commented line, it fails: <https://github.com/zach-klippenstein/compose-backstack/blob/master/sample/src/androidTest/java/com/zachklipp/compose/backstack/sample/SampleAppTest.kt#L20-L23>

I looked at the tests for Compose (on <http://cs.android.com|cs.android.com>), and the most notable difference is that this one is testing a custom activity, so it’s using `AndroidComposeTestRule` instead of `createComposeRule`. However, I also tried writing tests without using a custom activity, and while the simplest one works, most of them also fail on basic assertions: <https://github.com/zach-klippenstein/compose-backstack/blob/master/backstack/src/androidTest/java/com/zachklipp/compose/backstack/BackstackTest.kt>

hey, <@U0KMMQA20> ! Unfortunately the person being working on the testing story is not in this slack yet, could you please file a bug here in meantime so he can help you: <https://b.corp.google.com/issues/new?component=741505>. Thanks!

Done: <https://issuetracker.google.com/issues/152867839>

Tests work with dev08: <https://github.com/zach-klippenstein/compose-backstack/pull/20>
