With the [ViewMatchers](<https://developer.android.com/reference/android/support/test/espresso/matcher/ViewMatchers.html>) you can find view in the current view hierarchy.

To find a view, use the onView() method with a view matcher which selects the correct view. The [onView()](<https://developer.android.com/reference/android/support/test/espresso/Espresso.html#onView(org.hamcrest.Matcher%3Candroid.view.View%3E)>) methods return an object of type [ViewInteraction](<https://developer.android.com/reference/android/support/test/espresso/ViewInteraction.html>).

For example, finding a view by its R.id is as simple as:

onView(withId(R.id.my_view))

Finding a view with a text:

onView(withText("Hello World"))
