Answer 1

I had the same issue when I upgrade to AS 4.1

I resolved this by removing the following from the build.gradle (app) file

useLibrary 'android.test.runner'

All tests run to completion

Answer 2

i faced this issue yesterday after updating my Ubuntu 20.04 LTS ,i was installed android studio from sanp store . finally managed to solve issue temporary , if you are in linux you have to find installed directory of android studio and inside bin directory , run studio.sh with sudo , it seems that it is a permission issue

sudo ./android-studioInstalledDirectory/bin/studio.sh

Answer 3

I also faced this issue when I upgrade Android Studio to 4.1. Instead of removing the useLibrary line, I removed the testImplementation line I had before upgrading that brought in a version of JUnit explicitly.
