Перспектива разработки мобильного приложения, которое не потребуется скачивать и ждать review из App Store, очень заманчива, ведь аналогов привычного ПО существует несколько: Progressive Web Apps (PWA), Android Instant Apps (AIA) и Accelerated Mobile Pages (AMP). Как сделать верный выбор, найти «серебряную пулю», ведь у каждой из перечисленных технологий своя специфика разработки, поддержки и тестирования, сильные и слабые стороны. В докладе мы, по возможности, детально рассмотрим каждую из платформ, проведем сравнительный анализ альтенратив “обычными” мобильными приложениями. Давайте все вместе подготовимся к грядущим вызовам обеспечения качества в столь «необычных», новых проектах.

4. What is deep linking

5. Deep linking
Mobile deep linking, is the process of using a URI to link to specific pages or
locations within a mobile application.

6. It’s similar to web links

10. Use cases

11. Deep links have variable application
● Invites to the app
● Personalized onboarding experience
● Referral campaigns
● Retargeting
● Make e-2-e testing faster with direct navigation
● Android Instant Apps use Android App Links

12. The benefits from deep links usage
● Enhance the user experience
● Improve User Retention, Engagement, & Usage => 77% higher D7
retention
● Help Re-Engage Users
● Strengthen Marketing efforts
● Improve App Discoverability => >50% of users install an app after
friend’s recommendation
Word of mouth is one of the most effective ways of getting users to install your app

13. Developer’s pain

15. URI schemes
market://details?id=com.example.myapp
Deeplink Purpose
travelbrand:// Open the app
travelbrand://registration Open the app to the shopping cart checkout
screen
travelbrand://hotel/123 Open the app to a particular product ID

16. iOS: Universal links (UL) limitations
● UL won’t work if you paste the link into the browser URL field
● UL work with a shortener
● UL cannot be triggered via JS, unless it is part of a user action

17. iOS 12
● ITP changes
● Cookie privacy in Safari

18. Android specifics
● Firing an intent is not that easy
● The difference between deep links and App links: the
disambiguation dialog won’t appear

19. Android P: App Actions & Slices

20. Create links that work across different browsers

21. Create links that work across different browsers

22. Create links that work across different browsers

24. Native integrations with social media and
messaging apps

25. source

26. Tracking attribution
● Google Play INSTALL_REFERRER is not reliable
● Some apps (e.g. Facebook) remove referrer
● Apple App Store has no proper method to send specific
parameters after install to the app on the first launch
Solution => Fingerprints

27. Analyse what you’ve collected

28. Prevent installation fraud
Google Play Referrer API
Apple install validation
Flag installs on the backend side

29. But the biggest pain is...
Maintenance
• e.g. Facebook bug
• or Twitter update
• or iOS 11.2.x bug
• Telegram issue on iOS
• or any other bug that appears
right now...

30. Do you want to build your
own solution?

31. NO

32. Tester’s pain

33. Tester’s pain
● Big e2e cases are difficult to automate, sometimes impossible
● Fragmentation hell (OS, browsers, messengers) => different
deep linking flows
● A lot of dependencies on the third-parties
● Maintenance… again

34. Tester’s pain
● Some channels do not support deep linking easily
○ Snapchat stopped working in 2018
○ FB and Instagram Stories do not deep link yet

35. DL does not open the app… make sure
● … you are clicking on a deep link
● … deep link is not wrapped (e.g. http://bit.ly/AIA-QA)
● … you have configured your app correctly
● … you understand the expected behavior of deep links
● … the deep link domain matches your link domain

36. Helpful tools

37. UA switcher Chrome extension https://goo.gl/pPmwHp

38. Install referrer tester https://goo.gl/hFLmZC

39. Check webhooks with https://webhook.site/ or https://hookbin.com/

40. Subscribe to third-party app updates (e.g. AppShopper for iOS)

41. …and use spreadsheets

44. Testing tips
● Stay informed about all updates in OS, frameworks etc
● Subscribe to your competitors blogs
● Keep structure in your test results
● Be patient

45. Conclusions
● Be prepared to spend some time
● Don’t reinvent the wheel
● Be aware about all updates
● Deep links are cool and useful

46. Thank you!
It’s time for questions :)
