title: Test Artifact selector missing/gone from Build Variants in Android Studio 2 Beta 5
body: <p>In order to run Instrumentation Tests from within Android Studio, I typically select "Android Instrumentation Tests" as the test artifact to be built, via the Build Variants window. I recently upgraded to Android Studio 2 Beta 5, and the "Test Artifact" selector is no longer visible. Where did it go? Has some other configuration taken its place?</p>
