How to configure Android project for AndroidX Test

Question

I am having difficulty configuring my Android application for testing with AndroidX.

When I attempt to run my initial test I get this error:-

        val context = ApplicationProvider.getApplicationContext<Context>()
        assertEquals("com.research.jayunit", context.packageName)
    }
}

What am I doing wrong?

How can I resolve the gradle dependency issues?

I've followed this link that show show to configure AndroidX for testing

When I change my app gradle to include guava explicitly

   // https://mvnrepository.com/artifact/com.google.guava/guava
    implementation group: 'com.google.guava', name: 'guava', version: '27.1-android'

The dependency issues change to these below:-

I found a resolution
