Autogenerate unit test stubs on Android studio

I am creating the unit test for some legacy android codes.

Currently i need to manually create the unit test for each class/method in test/java.

Is there an automated way to auto generate all the test stubs? ideally from the Android studio IDE? (similar to how parasoft can autogenerate empty test stubs for C++ classes and methods).

I am using robolectric on Android studio 1.2.1
