I have the following list item that is used within a RecyclerView that has a vertical LinearLayout Manager. I am using espresso, and I would like to simulate clicking the id/action_save menu item. Below is my latest attempts at figuring this one out. I have tried using onData method combined with onChildView, but a MenuItem is not a View. The onView and withId methods works well if the menu item is located in a toolbar that is in the action bar, but while being embedded inside of a RecyclerView.
I have tried recording using the espresso recording feature in android studio, however, it inject code similar to this Espresso click menu item. When running the test case again causes the test to raise an exception.

Error
android.support.test.espresso.NoMatchingViewException: No views in hierarchy found matching: with id: com.variable.inspire:id/recyclerView
If the target view is not part of the view hierarchy, you may need to use Espresso.onData to load it from one of the following AdapterViews:android.support.v7.widget.MenuPopupWindow$MenuDropDownListView{92d26ac VFED.VC.. .F...... 0,0-515,252}
Update #1
This does not solve my question, but provides a workaround by displaying the menu item directly and not inside the overflow menu. My question still is using espresso can you open the overflow menu and click an item in it.
onView(allOf(withId(R.id.recyclerView), withParent(withId(R.id.container)))).perform(actionOnItemAtPosition(i, clickMenuItem(R.id.toolbar, R.id.action_save)));
