Is there a way to test custom Chrome tabs with Espresso?

Question

Here is the code stub.

Select a data item ListView. It works like the Chrome Custom tab was designed and opened:

onData(anything()).inAdapterView(withId(R.id.listView))
                                       .atPosition(0).perform(click());

Pause(5000);
Espresso.pressBack();

It may not seem that something appreciated on the tab or even pressed the return button of the device. Getting this error

Error : android.support.test.espresso.NoActivityResumedException: No 
activities  in stage RESUMED.

You forgot to start this operation. ( test.getActivity()or similar)?
