JUnit test in Android Studio: NoClassDefFoundError: junit/textui/ResultPrinter

Question

I have a fresh installation of Android Studio with a new Android project. I created one JUnit test class but I cannot run it:

It's my first attempt to use Android Studio and to do JUnit tests. So sorry if the solution is obvious.

Hmm yes, I have to run an "Android Test" instead of a "Unit Test". However, I am still confused in terms of Java and Android testing concepts. I think I need a few good tutorials. — , Dec 01 '14 at 11:50
Currently it seems impossible to run basic unit tests in Android Studio. Google only implemented the "intrumented" testing, with the whole Android environment. There is an issue open on that since last year https://code.google.com/p/android/issues/detail?id=75043 — Simon, Feb 05 '15 at 10:44

Following solution worked for me in windows:

1) in the environment variables add a new "system variables" ANDROID_SDK_HOME=D:\Program Files\android-sdk-windows (select your home directory of android sdk )

2) modify system variables Path, add "%Android_SDK_HOME%\tools;"

This actually worked, even when trying to run Android-dependent unittests (which needs to be enabled in the gradle file according to google) by including android{ ...testOptions { unitTests.returnDefaultValues = true }...} – AgentKnopf May 06 '15 at 21:11
