How to use 'InstrumentationTestRunner' to manager android library testcase with gradle

I have an android project like this:

ProjectA
----app
--------src
------------androidTest
------------main
----libA
--------src
------------androidTest
------------main
----libB
--------src
------------androidTest
------------main

Can I manager all TestCase (app and lib) with one InstrumentationTestRunner？

Use './gradlew clean connectionAndroidTest' to build project.
