This document discusses building mobile apps and testing them using Xamarin Test Cloud. It begins by outlining challenges in mobile development like the many device types, screen sizes, and OS versions. It then introduces Xamarin Test Cloud, noting that it uses thousands of physical devices located in a warehouse to test apps across various conditions. The document proceeds to explain how to create and run tests using the Xamarin.UITest framework and IDE integrations, and view results on the Test Cloud dashboard or via email. It concludes that Xamarin Test Cloud allows for easy and fast UI testing across real devices.

Creating Tests
16
• Xamarin.UITest
• C# based on NUnit
• Also Appium, Espresso, …
• Query on any VisualElement
property
• Xamarin.Forms; AutomationId
• Needs manual mapping!

17. @jfversluis |
Creating Tests - Test Recorder
17
• Visual Studio & Xamarin Studio
• Works a bit different
• Record tests by clicking through
your app
• Simulator or physical
• Just add assertions!
• Replay or send to Test Cloud

18. @jfversluis |
Running Tests
18
• Locally on physical device or
simulator/emulator
• Upload manually by console
• Directly from IDE (Visual Studio)
• Integrated in automated builds

19. @jfversluis |
Running Tests - Results
19
• Through e-mail
• Integrated in VSTS
• Test Cloud dashboard

20. @jfversluis |
It’s a wrap!

• Quality on mobile is important
• Easy & fast UI tests
• Running on physical devices
• Not just for Xamarin apps
