11. Robot Pattern / “Page Object” 
 (Martin Fowler)
12. No Framework/Library just a layer for our tests…
13. https://martinfowler.com /bliki/PageObject.html
14. Plain Tests UI “ViewController/Presenter/Other”
15. Plain Tests UI “ViewController/Presenter/Other” Robots
16. Defines “How”
17. Testing UI
18. @Test fun test_login_showMainView() { // write email // write password // click login button // check if user logged in successfully } Login test
19. @Test fun test_login_showMainView() { Espresso.onView(ViewMatchers.withId(R.id.loginUsernameEditText)) .perform(ViewActions.typeText("james@bond.com"), ViewActions.closeSoftKeyboard()) Espresso.onView(ViewMatchers.withId(R.id.loginPasswordEditText)) .perform(ViewActions.typeText(“007”), ViewActions.closeSoftKeyboard()) Espresso.onView(ViewMatchers.withId(R.id.loginSubmitButton)).perform(ViewActions.click()) Espresso.onView(AllOf.allOf(ViewMatchers.withText("Main"))) .check(ViewAssertions.matches(ViewMatchers.isDisplayed())) }
20. Applying Robots…
21. @Test fun test_login_showMainView() { Espresso.onView(ViewMatchers.withId(R.id.loginUsernameEditText)) .perform(ViewActions.typeText("james@bond.com"), ViewActions.closeSoftKeyboard()) Espresso.onView(ViewMatchers.withId(R.id.loginPasswordEditText)) .perform(ViewActions.typeText(“007"), ViewActions.closeSoftKeyboard()) Espresso.onView(ViewMatchers.withId(R.id.loginSubmitButton)).perform(ViewActions.click()) Espresso.onView(AllOf.allOf(ViewMatchers.withText("Main"))) .check(ViewAssertions.matches(ViewMatchers.isDisplayed())) }

34. Base “Pattern”
35. class LoginRobot { fun clickLogin() { onView(withId(R.id.loginButton)).perform(typeText(text), closeSoftKeyboard()) } }
36. class LoginRobot : BaseRobot() { fun clickLogin() { click(R.id.loginButton) } }
37. open class BaseRobot { fun click(id: Int) { onView(withId(id)).perform(ViewActions.click()) } } class LoginRobot : BaseRobot() { fun clickLogin() { click(R.id.loginButton) } }
38. open class BaseRobot { fun click(id: Int) { takeScreenshot("before_click") onView(withId(id)).perform(ViewActions.click()) takeScreenshot(“after_click”) } fun takeScreenshot(screenName: String) { //... } } class LoginRobot : BaseRobot() { fun clickLogin() { click(R.id.loginButton) } }
39. Builder Pattern
40. class MapApi { constructor(host: String) {} constructor(host: String, port: Int, listener: Listener) {} } class Order { val mapApi = MapApi(“http://droids4droids.com/places", 23, null) } class Order { val mapApi = MapApi(“http://droids4droids.com/places", 23, this) }
41. class MapApi { object Builder { fun withHost(host: String): Builder { return this } fun withPort(port: Int): Builder { return this } fun withListener(listener: Listener): Builder { return this } fun build() : MapApi { return MapApi(…) } } }
42. class MapApi { object Builder { fun withHost(host: String): Builder { return this } fun withPort(port: Int): Builder { return this } fun withListener(listener: Listener): Builder { return this } fun build() : MapApi { return MapApi(…) } } }
43. class MapApi { object Builder { fun withHost(host: String): Builder { return this } fun withPort(port: Int): Builder { return this } fun withListener(listener: Listener): Builder { return this } fun build() : MapApi { return MapApi(…) } } } class Order { val mapApi: MapApi = MapApi.Builder.withHost(“http://droids4droids.com/places”) .withPort(23) .build() }
44. class MapApi { object Builder { fun withHost(host: String): Builder { return this } fun withPort(port: Int): Builder { return this } fun withListener(listener: Listener): Builder { return this } fun build() : MapApi { return MapApi(…) } } } class Order { val mapApi: MapApi = MapApi.Builder.withHost(“http://droids4droids.com/places”) .withPort(23) .build() }
45. Applying builder pattern…
46. class LoginRobot { fun writeEmail(text: String) { onView(withId(R.id.loginUsernameEditText)).perform(typeText(text), closeSoftKeyboard()) } fun writePassword(text: String) { onView(withId(R.id.loginUsernameEditText)).perform(typeText(text), closeSoftKeyboard()) } fun clickLoginButton(): MainRobot { onView(withId(R.id.loginSubmitButton)).perform(ViewActions.click()) return MainRobot() } }

52. Simple Factory Pattern
53. interface Book class PaperbackBook(val title: String, val author: String) : Book val book1 = PaperbackBook("Secret agents for Dummies", "James Bond") val book2 = PaperbackBook("Secret agents for Dummies", "James bond”) val book3 = PaperbackBook("Secret agents for Dummies", "James Bod")

55. interface Book internal class PaperbackBook(val title: String, val author: String) : Book object PaperbackBookFactory { fun jamesBondBook(title: String): Book { return PaperbackBook(title, "James Bond"); } } val book = PaperbackBookFactory.jamesBondBook("Secret agents for Dummies”) val book2 = PaperbackBookFactory.jamesBondBook("Secret agents for Dummies 2”)
56. interface Book internal class PaperbackBook(val title: String, val author: String) : Book object PaperbackBookFactory { fun jamesBondBook(title: String): Book { return PaperbackBook(title, "James Bond"); } } val book = PaperbackBookFactory.jamesBondBook("Secret agents for Dummies”) val book2 = PaperbackBookFactory.jamesBondBook("Secret agents for Dummies 2”)
