10. Espresso - Core API Espresso.
11. Espresso - Core API Espresso.onView()
12. Espresso - Core API onView( )
13. Espresso - Core API onView(withId(R.id.button))
14. Espresso - Core API onView(withId(R.id.button)) ViewInteraction ViewMatcher
15. Espresso - Core API onView(withId(R.id.button)) ViewInteraction ViewMatcher NoMatchingViewException - gdy nie ma widoku, który opisaliśmy
16. Espresso - Core API onView(withId(R.id.button)) ViewInteraction ViewMatcher NoMatchingViewException - gdy nie ma widoku, który opisaliśmy AmbiguousViewMatcherException - gdy nasz opis pasuje do dwóch i więcej widoków

18. ViewMatchers ViewInteraction passwordInput = onView(withHint("Lösenord"))
19. ViewMatchers ViewInteraction loginButton = onView(withId(R.id.loginBtn))
20. Layout Inspector
21. ViewMatchers - złożone allOf(Matcher<? super T>... matchers) - każdy z podanych
22. ViewMatchers - złożone allOf(Matcher<? super T>... matchers) - każdy z podanych allOf( withText("Help me!"), withHint("Attention"), hasSibling( withId(R.id.sos_button) ) )

78. Intent Weryfikacja intentów(matching) - sprawdzenie czy dany Intent został wysłany intended(allOf( hasAction(equalTo(Intent.ACTION_VIEW)), hasCategories(hasItem(equalTo(Intent.CATEGORY_BROWSABLE))), hasData(hasHost(equalTo("www.google.com"))), hasExtras(allOf( hasEntry(equalTo("key1"), equalTo("value1")), hasEntry(equalTo("key2"), equalTo("value2")))), toPackage("com.android.browser")));
