We seem to have an issue with AndroidComposeRule, we have a simple test with waitUntil {} function:
@RunWith(AndroidJUnit4::class)
class IdenfyFaceReauthenticationFlowTests {
@get:Rule
val composeTestRule = createAndroidComposeRule<FaceReauthenticationActivity>()
private lateinit var faceReauthenticationActivity: FaceReauthenticationActivity
@Before
fun setUp() {
faceReauthenticationActivity = composeTestRule.activity
faceReauthenticationActivity.idenfyMainViewModel.idenfyInternalSettings.isInitialViewClosed = false
}
@Test
fun test1() {
composeTestRule.waitUntil(8000) {
composeTestRule.onAllNodesWithText(faceReauthenticationActivity.getString(R.string.idenfy_camera_onboarding_view_continue_button_title_v2)).fetchSemanticsNodes(false).isNotEmpty()
}
composeTestRule.onNodeWithText(faceReauthenticationActivity.getString(R.string.idenfy_camera_onboarding_view_continue_button_title_v2)).performClick()
Thread.sleep(6000)
//Face Reauthentication Results View V2
IdenfyView().waitForView(ViewMatchers.withId(R.id.idenfy_button_face_reauthentication_results_continue)).perform(
ViewActions.click())
Thread.sleep(1000)
val activityResult = composeTestRule.activityRule.scenario.result!!
activityResult.resultData.setExtrasClassLoader(this::class.java.classLoader)
val faceReauthenticationResult: FaceReauthenticationResult =
activityResult.resultData.getParcelableExtra(IdenfyController.IDENFY_FACE_REAUTHENTICATION_RESULT)!!
assert(faceReauthenticationResult.faceReauthenticationStatus == FaceReauthenticationStatus.SUCCESS)
}
@After
fun tearDown() {
composeTestRule.activityRule.scenario.close()
}
}
The problem that we are facing, is that SOMETIMES the test fails with the following error:
androidx.compose.ui.test.junit4.android.ComposeNotIdleException: Idling resource timed out: possibly due to compose being busy.
IdlingResourceRegistry has the following idling resources registered:
- [busy] androidx.compose.ui.test.junit4.android.ComposeIdlingResource@df5cec9

The test seems to get stuck at this line (The composable is definitely visible):
composeTestRule.waitUntil(8000) {
composeTestRule.onAllNodesWithText(faceReauthenticationActivity.getString(R.string.idenfy_camera_onboarding_view_continue_button_title_v2)).fetchSemanticsNodes(false).isNotEmpty()
}
Our dependencies (With 1.0.5 compose version):
//Compose
implementation “androidx.compose.ui:ui:$compose_version”
implementation “androidx.compose.material:material:$compose_version”
implementation “androidx.compose.ui:ui-tooling-preview:$compose_version”
implementation ‘androidx.lifecycle:lifecycle-runtime-ktx:2.4.0’
implementation ‘androidx.activity:activity-compose:1.4.0’
//Compose testing
debugImplementation “androidx.compose.ui:ui-test-manifest:1.0.5"
Is something wrong in our implementation?
EDIT
After some more tries, we discovered the cause of this problem, we have two mutable states:
val currentInstructionDescription: MutableState<String> = remember {
mutableStateOf("")
}
val progress = remember {
mutableStateOf(0.0f)
}
These two states are changing all the time in the view (every second), one of them changes the progress of a progress bar, another updates a text:
LaunchedEffect(key1 = Unit, block = {
val timer = (0..Int.MAX_VALUE)
.asSequence()
.asFlow()
.onEach { delay(1000) }
timer.collect {
progress.value = progressValueInFloat // increasing value
currentInstructionDescription.value = "Custom String"
}
})
Having this code disabled, the tests run fine and idling resources get idled. Maybe there is something wrong with our implementation of this code?
