Check DatePicker calendar value in Android Espresso framework

I've got an activity with two DatePicker controls and some text inputs and buttons. I would like to test some scenario by espresso:

1. Set date to first DatePicker.
2. Set some text and click buttons witch trigger my business logic and set date to second DatePicker.
3. Check date of second DatePicker.

In 3rd step I would like to do something like onView(withId(R.id.end_date_picker)).check(matches(withText("25-01-2017")));. What can I use instead of withText to check DatePicker Calendar/Date value? Thanks for any help.
