Testing usage of Firebase create user functions with Coroutines and calling await() leads to "T-CodePudding

I have a simplified test case where I'm calling createUserWithEmailAndPassword(...).await() from FirebaseAuth that leads to the exception

java.lang.IllegalStateException: This job has not completed yet

I'm using the InstantTaskExecutorRule but this doesn't help.

Here is my simplified test class:

import androidx.arch.core.executor.testing.InstantTaskExecutorRule
import com.google.firebase.auth.ktx.auth
import com.google.firebase.ktx.Firebase
import kotlinx.coroutines.tasks.await
import kotlinx.coroutines.test.runBlockingTest
import org.junit.Rule
import org.junit.Test

class FirebaseCoroutineTest {
    @get:Rule
    val instantTaskExecutorRule = InstantTaskExecutorRule()

    val auth = Firebase.auth.apply {
        this.useEmulator("10.0.2.2", 9099)
    }


    @Test
    fun testCreateUser() = runBlockingTest {
        auth.createUserWithEmailAndPassword("[email protected]", "testpwd").await()

    }
}

What's the correct way to do this test.

CodePudding user response：

using runBlocking instead of runBlockingTest solves the issue.
