Answer 1

You needn't to add "testing-support-lib", neither "espresso:espresso-core". They are transitive added when "espresso:espresso-contrib" is added.

build.grade

dependencies {
    androidTestCompile 'com.android.support.test:runner:0.3'
    androidTestCompile 'com.android.support.test:rules:0.3'
    androidTestCompile 'com.android.support.test.espresso:espresso-contrib:2.2'
}

Usage:

onView(withId(R.id.recyclerView)).perform(
            RecyclerViewActions.actionOnItemAtPosition(0, click()));
