The SourceSet \'instrumentTest\' is not recognized by the Androi         


        

Answer 1

instrumentTest has been deprecated and does not work with modern Gradle versions - which you probably updated in your project when upgrading Android Studio.

Replace instrumentTest with androidTest and it'll work.
