Robotium gradle-based Android Studio

Question

I'm struggling to get Robotium to work on the gradle-based Android Studio and I can't find the way to run the test with gradle CLI. I Placed robotium.jar "robotium-solo-5.4.1.jar" into the libs folder, Added as library. In the src folder I created another folders androidTest->java->package for the test source with the same name as app’s package name-> Test.java "java" (inside "androidTest") is a green color.

UI: as usual using Android Studio Run menu - working.

console: in the terminal enter the following command: gradlew connectedAndroidTest = not working. I also tried "gradlew test", test results get generated in build/test-report, but they show that no tests were found.

I want to run Robotium test with gradle CLI without connecting device, because I want to run tests in the Android emulator in CircleCI.

Is there a problem on my build.gradle / test file or is there a something I missing ?

I would really appreciate any help!

***** This is my build.gradle file

apply plugin: 'com.android.application'
