ViewMatchers – A collection of objects that implement Matcher<? super View> interface. You can pass one or more of these to the onView method to locate a view within the current view hierarchy.

ViewActions – A collection of ViewActions that can be passed to the ViewInteraction.perform() method (for example, click()).

ViewAssertions – A collection of ViewAssertions that can be passed the ViewInteraction.check() method. Most of the time, you will use the matches assertion, which uses a View matcher to assert the state of the currently selected view.
