testing-samples: AndroidX.test dependency error

androidTestImplementation 'androidx.test.ext:junit:1.1.1-alpha02'
androidTestImplementation 'androidx.test:runner:1.1.2-alpha02'
androidTestImplementation 'androidx.test:rules:1.1.2-alpha02'

After adding the above dependency, the Espresso test run fails by giving below error. I am not using any other annotations other than @rule and @test, @RunWith. If I remove above dependency “androidx.test.ext:junit:1.1.1-alpha02” and drowngrade the runner and rules dependency to older version 1.1.0-alpha4 then it won’t throw the below error.
