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"))
