Anyone faced an issue where testing a compose UI doesn;t launch the compose itself, yet the test keeps on running


[Contd in thread]

class SampleUITesting {

@get:Rule
val composeTestRule = _createAndroidComposeRule_<ComponentActivity>()

@Before
fun setup() {
composeTestRule.setContent {
Box(modifier = Modifier._fillMaxSize_()) {
Column(
verticalArrangement = Arrangement.spacedBy(12.dp),
modifier = Modifier._align_(Alignment.Center)
) {
val context = LocalContext.current
Button(
onClick = {
Toast.makeText(context, "Clicked!", Toast._LENGTH_SHORT_).show()
}
) {
Text(text = "Button")
}

Button(onClick = {

}) {
Text(text = "Clicked")
}
}
}
}
}

@After
fun tearDown() {

}

@Test
fun perform() {
Log.d("ComposeUITesting", "Started")

composeTestRule._onNodeWithText_("Button")._performClick_()

composeTestRule._onNodeWithText_("Clicked!")._assertIsDisplayed_()
}

}

On running the test I just get 2 popups to allow the app to be installed on the device and this keeps running.

One wierd thing that I observed was when I force stopped the app from settings the test stopped. But I never see a UI being shown while test is running

Is the UI using progress bar or some sort of infinite animation. I think I remember something like that, where you had to replace compose animator by a fake in order to be able to run the test, or remove the progress bar when in tests

Toast is not a composeable. You cannot assert it with the compose rule.

[Mahmoo]

@Pablichjenkov the compose ui is very simple as shown in the setCkntent method... No loaders

[Mahmoo]

@Chrimaeon even though I remove the toast

It behaves the same

[Pablichjenkov]

Ah sorry, I replied without reading your code. Other than that issue I mentioned, I haven't seen any similar to yours.

I am able to run this on emulator now.. but not on real device
