1. (Kotlin + patterns) * ui-tests = happy developer Daniel Gomez Rico Android Lead Developer at Barista Ventures @aquicaipivara
2. Code Smell
3. Code Smell Test
4. 1. Login Example login app 2. Logout
5. @Test fun test_login_showMainView() { // write email // write password // click login button // check if user logged in successfully } Test login works

10. No Framework/Library just a layer for our tests…

29. Builder Pattern
30. class MapApi { constructor(host: String) {} constructor(host: String, port: Int, listener: Listener) {} } class Order { val mapApi = MapApi("http://pataconf.com/places", 23, null) }
31. 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(…) } } }
32. 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(…) } } }
33. 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://pataconf.com/places") .withPort(23) .build() }

42. Simple Factory Pattern
43. 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")
44. 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")
45. 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”)
46. 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”)
47. Applying builder pattern…
48. class MainTests {
 
 @Test

54. Base “Pattern”
55. class LoginRobot { fun clickLogin() { onView(withId(R.id.loginButton)).perform(typeText(text), closeSoftKeyboard()) } }
56. class LoginRobot : BaseRobot() { fun clickLogin() { click(R.id.loginButton) } }
57. open class BaseRobot { fun click(id: Int) { onView(withId(id)).perform(ViewActions.click()) } } class LoginRobot : BaseRobot() { fun clickLogin() { click(R.id.loginButton) } }
58. 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) } }
