java.lang.NoClassDefFoundError: Failed resolution of: Landroidx/test/platform/io/FileTestStorage;

Question

Firstly I did not have androidTest Package in my App, So I created using Run-> Record Espresso Test, So it Created an androidTest package. But Getting this Exception in Logcat while running an Instrumented test. I have Gone through lot of solutions on Stackoverflow and Searched a lot on Google, Nothing works as of now.

Here is my code.

import androidx.test.ext.junit.runners.AndroidJUnit4
import androidx.test.filters.SmallTest
import org.junit.Assert.assertEquals
import org.junit.Test
import org.junit.runner.RunWith

@SmallTest
@RunWith(AndroidJUnit4::class)
class MainActivityTest {

    @Test
    fun mainActivityTest() {
        assertEquals(2, 1+1)
    }
}

And build.gradle is

apply plugin: 'com.android.application'
apply plugin: 'kotlin-android'
apply plugin: 'kotlin-android-extensions'
apply plugin: 'com.google.gms.google-services'
apply plugin: 'com.google.firebase.firebase-perf'
