I can create the following tests inside an inner class which lives in another class or interface, like this:

public interface SampleTest {

    @Test
    void sampleTest();

    public static final class DefaultImpls {
        @Test
        public static void sampleTest() {
            // default impl here
        }
    }
}

or

public class OuterClass {
    public static final class InnerClass {
        @Test
        public static void innerTest() {
            // test impl here
        }
    }
}

If I create these as JVM tests, everything works perfectly. If they are Android instrumentation tests, I cannot run them from Android Studio. For example, if I try to run the second example, Android Studio generates the following adb command:

adb shell am instrument -w -r -e debug false -e class com.example.OuterClass.InnerClass#innerTest com.example.test/android.support.test.runner.AndroidJUnitRunner

Notice that it's using OuterClass.InnerClass rather than OuterClass$InnerClass. This seems like a definite bug to me.

If I manually change the adb command that was run, I start running into shell escaping problems, so watch out for that if you're trying to reproduce this issue. To get it to really work, I needed to run:

adb shell 'am instrument -w -r -e debug false -e class com.example.OuterClass\$InnerClass#innerTest com.example.test/android.support.test.runner.AndroidJUnitRunner'

Notice the ' around am ... and the \$.
