What is Xamarin Test Cloud? Top 5 Misconceptions New Stuff and Secret Stuff

Automated Testing on thousands of mobile devices

So how does it work?

So how does it REALLY work?

Create Tests and run them locally on simulator or device right from the IDE.

Xamarin.UITest (C#) / Calabash (Ruby)

Automatically execute tests in the cloud in parallel from a pool of real iOS & Android devices.

Xamarin Test Cloud

• Interact with UI controls in your app using gestures

• Declarative query language to identify views on screen

• Wait for events to occur (e.g., no spinner visible)

• Generate screenshots

• App-lifecycle APIs (start/stop, etc)

• Low-level APIs provides access to reflectively call methods on app objects

Automated UI Testing

//Example in C# using Xamarin.UITest app.Tap ("Help"); app.Tap (e => e.Id ("history-btn"));app.WaitForElement (e => e.Text ("Ink"));app.Screenshot ("View the purchasing history");

Top 5 Common Misconceptions

That's nice, too bad my App isn't built with Xamarin.

Misconception #5

Xamarin Test Cloud works with every native and hybrid mobile app - it doesn't matter how it was built.

Xamarin / C# Xcode / Objective-C / Swift Android Studio / Java Cordova / JS React Native / JS ...

Test Cloud is WAAAY too expensive!

Misconception #4

Well, that's subjective :)

https://www.xamarin.com/test-cloud

Xamarin.UITest is completely free to use!

Wow! Cool! I'd love to use it! Too bad we don't have time

to write tests...

Misconception #3

We Understand!

"How can you afford not to test?" - Niels Frydenholm, eBay classified

If you think you don't have time, you're probably wrong ;) (I'm a link!)

Also: How hard it is to get started with Continuous Delivery on Mobile?

Continuous Delivery for Mobile Apps: Yes We Can!

Also watch this space for announcements this month :)

So these 'devices', they're emulators. ... Right?!?

Misconception #2

NO! They're real non-jailbroken devices!

I can build my own Test Labs! How hard can it be?

Misconception #1

So you want to build your own Test Cloud?

Stable WiFi

Automated parallel execution infrastructurePop-Ups (e.g., update)

Device Stability (Unplugging/replugging devices, transparent reruns, cleaning)

Test Data aggregation, Crash detection, screenshots, video,...

Device automation

Managing Macs

Managing and Procuring Devices

Device Maintenance

Provisioning Profiles Google Play Services

New Stuff & Secret Stuff

New and Secret stuff

Android Fast Clearing of AppData Android Video recording (use: --test-param screencapture:true)

New and Secret stuff

iOS: upload dSyms (without), UITest 2.0.0 / Calabash 0.20.0 / iOS10 / the Device Agent interface

New and Secret stuff

UITest

Hyper-parallel runs vs serial, CLI runs (see demo)) UITest 2.0

New and Secret stuff

New Frameworks: Appium, Espresso

• Cross-platform C#-based API

• Run with NUnit

• Xamarin/Visual Studio or CLI

• SpecFlow support

Xamarin.UITest• Write Tests in Ruby

• Supports BDD, run with Cucumber

• RubyMine or CLI

Calabash

• Write Tests using Selenium/Webdriver

• e.g. Java, (Python, JavaScript, ...)

• Leverage Selenium resources

Appium Espresso (XCUITest?)• Official tools

• Java/Obj-C/Swift

• Not cross platform

Thanks! Questions?

Happy to help people get set up with testing here today!
