I'm trying to write the test for my composes. So I have a test class put in AndroidTest just like this:
@HiltAndroidTest
@UninstallModules(AuthenticationModule::class, AppModule::class)
class AuthenticationScreenTest {
@get:Rule(order = 0)
val hiltRule = HiltAndroidRule(this)
@get:Rule(order = 1)
val composeRule = createAndroidComposeRule<MainActivity>()
@Inject
lateinit var setting: Setting
@Before
fun setup() {
hiltRule.inject()
composeRule.setContent {
val navController = rememberNavController()
RefectoryTheme {
NavHost(
navController = navController,
startDestination = AuthenticationNavGraph.AuthenticationScreen.route
) {
composable(AuthenticationNavGraph.AuthenticationScreen.route) {
AuthenticationScreen(navController = navController, setting = setting)
}
}
}
}
}
@Test
fun checkLoadingButtonExpantion() {
composeRule.onNodeWithTag(testTag = AUTHENTICATION_SCREEN_LOGIN_BUTTON)
.assertIsDisplayed()
}
}
but I keep getting the 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.ComposeIdlingResource@a005df5
All registered idling resources: Compose-Espresso link
The android emulator is launched, test compiles successfully, but it seems it can't find the object. I also have added a test tag to the modifier of the object:
LoadingButton(
buttonText = stringResource(id = R.string.login),
isExpanded = state.isLoginExpanded,
modifier = Modifier
.padding(MaterialTheme.spacing.medium)
.align(Alignment.CenterHorizontally)
.testTag(AUTHENTICATION_SCREEN_LOGIN_BUTTON)
) {
viewModel.onEvent(AuthenticationEvent.Login)
}
But after 28 seconds, I got the error as mentioned above. What am I missing?
I just realized what the problem was. I am using Lottie on my screen, and the animation is infinity repeating. So I don't know why but it seems that it doesn't allow testing to go through. The tests ran without any problem when I commented the Lottie section.
