The ViewInteraction object is used to perform the action on the UI element. In the above example, we are using the withId() method of the ViewMatchers class to create a Matcher object. The Matcher object is used to match the UI element with the given id. The onView() method accepts the Matcher object as an argument. The onView() method returns the ViewInteraction object. The check() method of the ViewInteraction object is used to perform the check operation. The check() method accepts the ViewAssertion object as an argument. The ViewAssertion object is used to assert the UI element. In the above example, we are using the matches() method of the ViewAssertions class to create the ViewAssertion object. The matches() method accepts the Matcher object as an argument. The matches() method returns the ViewAssertion object. The onView() method accepts the ViewAssertion object as an argument. The onView() method returns the ViewInteraction object. The check() method of the ViewInteraction object is used to perform the check operation. The check() method accepts the ViewAssertion object as an argument. The ViewAssertion object is used to assert the UI element.
