I'm trying to follow Android Developer Docs to write an Instrumented Unit Test, but, of course, it doesn't work. I am getting the error:

Custom runner class AndroidJUnit4 should have a public constructor with signature AndroidJUnit4(Class testClass)

when ever I run my example test:

package com.devetry.ytp



import android.content.Context

import android.support.test.InstrumentationRegistry

import android.support.test.rule.ActivityTestRule

import android.support.test.runner.AndroidJUnit4

import androidx.test.filters.LargeTest

import org.junit.Before

import org.junit.Test

import org.junit.runner.RunWith



import androidx.test.runner.AndroidJUnitRunner

import org.junit.Assert

import org.junit.Rule



@RunWith(AndroidJUnit4::class)

class ExampleAndroidTest {



    /**

     * VARIABLES

     */







    /**

     * LIFE CYCLE

     */





    /**

     * Example Android Test

     *

     * An example android test

     */

    @Test

    fun exampleAndroidTest() {

        val context = InstrumentationRegistry.getTargetContext()

        Assert.assertEquals("com.devetry.ytp", context.packageName)

    }



}

I have tried tried multiple solutions to this specific error I found online, but like most things Android, the solution was either outdated or just simply didn't work. Unfortunately, of all of the solutions, I was unable to even recognize a common theme, thus leaving me stranded.

How can I resolve the error and just get an Instrumented Unit Tests to run?
