Transcript

1. UI Automation in Mobile Apps by Andrey Kozlov Senior iOS Developer @thetrainline
2. Agenda • Why Automation Testing? • Tooling • Problems • Approach • Mocking and Stubbing • Analytics testing • Next steps
3. Why Automaton Testing
4. Why Automaton Testing • Help QA team to reduce regression testing • Increase Application Quality • Increase confidence • Faster feedback on changes. • Catch issues earlier in a process • Bigger test coverage • Automated way of testing • RSP accreditation
5. Right tool for a job?
6. Right tool for a job? • KIF • Calabash • Frank • Appium • Apple Xcode UI Tests
7. Why Apple Xcode UI Tests? • Native tool • More stable • Apple support and updates • Improves along with platform • Same development language as for main App • Familiar environment for Developers • Good documentation • It works!
8. Problems?
9. Problems? • Speed • Maintainability and Reusability • Reliability • Still UnitTest type of tests. • All team involvement including QA team
10. Solved
11. Solved • Testing Framework. • Stubbing Service • Configuration Framework • FeatureToggling Framework
12. Testing Framework • Abstraction for element matching • Simplified way of writing test scenarios • BDD-ish style of tests • Alert handling • Custom checks and Assertions • Custom methods of interaction with elements • Navigation between screens • Integrated Stubbing • e.t.c.
13. Example func testLoginWithCorrectDetails() { let loginScreen = GivenApplicationIsOn(LeisureLoginScreen()) WhenUserEntersText("a@a.com", into: loginScreen.emailTextField) WhenUserEntersText("password", into: loginScreen.passwordTextField) WhenUserTaps(on: loginScreen.loginButton) ThenLabelShouldExist("Account") } Login Scenario
14. Example func testBuyingSingleJourneyWithMultiplePassengersMultipleRailcards() { GivenApplicationIsOn(PlanAndBuySearchScreen()) let journey = StubJourney(origin: "YRK", destination: "NCL").setType(.single).setAdults(3).setRailcards(["16-25 Railcard","JobCentrePlus Discount Card"]) WhenUserSearchTrains(journey: journey, on: PlanAndBuySearchScreen()) ThenUserShouldBeOnScreen(JourneyResultsScreen()) ThenLabelShouldExist("Valid railcards savings applied") WhenUserNavigate(to: PaymentSummaryScreen()) ThenLabelShouldExist("JobCentrePlus Discount Card, 16-25 Railcard discounts applied") WhenUserNavigate(to: AddPaymentCardScreen()) WhenUserEnterCardDetails(on: AddPaymentCardScreen(), cardName: .VisaCredit, email: "a@a.com") ThenUserShouldBeOnScreen(PaymentSummaryScreen()) WhenUserEntersText("111", into: PaymentSummaryScreen().cvvTextField) WhenUserTaps(on: PaymentSummaryScreen().payByCardButton) ThenUserShouldBeOnScreen(MyTicketsScreen(), timeout: 20.0) } Making purchase and check booking is there
15. Mocking and Stubbing
16. Analytics Testing
17. Analytics Testing
18. Configuration • Using Xcode Schemes to organise tests in bundles • Use of Environment variables to communicate with Application under Test • Stubbing Feature toggles using using Environment variables • Using low level xcodebuild command for more flexible test selection • Passing Stubbing service URL and GUID
19. What is next?
20. What is next? • Open sourcing • Update to use Swift 4 and Xcode 9 features • Release Framework and Stubbing Service Template in Swift • Implement toolset to help with UI Automation for iOS
