[Hilt] onCreate() in my Application doesn't called on Instrument test about dagger HOT 4 CLOSED

Right, @HiltAndroidTest will generate a test application for you. So @HiltAndroidApp one will be unused. I think @CustomTestApplication may help you

from dagger.

I just solve this application onCreate by implement in @Before function.

@Before
    fun setUp() {
        hiltRule.inject()
        runTest {
            airportsFtsRepository.deleteAndInsertAll(
                airportFtsEntitiesTestData
            )
        }
    }

Thank you to stay with me.

Hi, did you try adding logs to onCreate to verify onCreate was indeed not called? launch is an asynchronous call, so it may not get to run after the test finishes if you don't have some idling or blocking mechanism to make sure the launched task was executed.

Yes, I tested it with log and no onCreate called. I think we replaced the Application to HiltTestApplication. It seemed to bring this situation.
