KoinApplicationAlreadyStartedException with Robolectric

[kfaraj]

Describe the bug
When running tests on Robolectric, subsequent tests fail with the following exception:

A Koin Application has already been started
org.koin.core.error.KoinApplicationAlreadyStartedException: A Koin Application has already been started
	at org.koin.core.context.GlobalContext.register(GlobalContext.kt:44)
	at org.koin.core.context.GlobalContext.startKoin(GlobalContext.kt:63)
	at org.koin.ksp.generated.MainApplicationGencom_kfaraj_samples_koinKt.startKoin(MainApplicationGencom$kfaraj$samples$koin.kt:16)
	at org.koin.ksp.generated.MainApplicationGencom_kfaraj_samples_koinKt.startKoin$default(MainApplicationGencom$kfaraj$samples$koin.kt:15)
	at com.kfaraj.samples.koin.MainApplication.onCreate(MainApplication.kt:12)
	at android.app.Instrumentation.callApplicationOnCreate(Instrumentation.java:1381)
	at org.robolectric.android.internal.RoboMonitoringInstrumentation.callApplicationOnCreate(RoboMonitoringInstrumentation.java:157)
	at org.robolectric.android.internal.AndroidTestEnvironment.lambda$installAndCreateApplication$2(AndroidTestEnvironment.java:407)

To Reproduce
Run the following tests on Robolectric:

import org.koin.ksp.generated.*

@KoinApplication
class MainApplication : Application() {

    override fun onCreate() {
        super.onCreate()
        startKoin()
    }

}

class MainActivity : ComponentActivity()

@OrderWith(Alphanumeric::class)
@RunWith(AndroidJUnit4::class)
class MainActivityTest {

    @Test
    fun launchActivity() {
        launchActivity<MainActivity>()
    }

    @Test
    fun relaunchActivity() {
        launchActivity<MainActivity>()
    }

}

Expected behavior
Subsequent tests running on Robolectric should not fail.

Koin project used and used version (please complete the following information):
koin-android version 4.1.1
koin-annotations version 2.3.1

Additional moduleDefinition

• Running the same tests on Android instead of Robolectric works properly.
• Running the same tests using Hilt instead of Koin also works properly.

I ended up with the following workaround:

import org.koin.ksp.generated.*

@KoinApplication
class MainApplication : Application() {

    override fun onCreate() {
        super.onCreate()
        startKoin()
    }

    override fun onTerminate() {
        super.onTerminate()
        stopKoin()
    }

}
