Automate iOS native apps with Xamarin.UITest

  • Artikkel

Important

Visual Studio App Center is scheduled for retirement on March 31, 2025. While you can continue to use Visual Studio App Center until it is fully retired, there are several recommended alternatives that you may consider migrating to.

Learn more about support timelines and alternatives.

To follow the guide, you need access to the app source code.

Add an automation backend to your app

Part of the Xamarin.UITest toolchain is the backend that runs alongside the app. The Xamarin.UITest test script communicates with the backend, which executes the commands on the simulator or device.

Because Xamarin.UITest shares backend with Calabash, first step is to link the calabash.framework, using one of the three methods from the Calabash doc.

You should see that the server is running in Xcode, after following the Calabash guide.

You build the .app file from the terminal like below:

Note

.app files only work simulators

 xcrun xcodebuild \
  -project ProjectFile.xcodeproj \
  -configuration ConfiguratonWithCalabashLinked \
  -sdk iphonesimulator \
  ARCHS="x86_64" \
  VALID_ARCHS="x86_64" \
  ONLY_ACTIVE_ARCH=NO \
  -scheme SchemeWithCalabashLinked \
  -derivedDataPath DerivedData \
  build

The following switches must match your project:

  • -project
  • -configuration
  • -scheme

Run your Xamarin.UITest on a simulator

With the Calabash backend setup, the next step is to configure your Xamarin.UITest so that it opens your app on a simulator. See the Working with Simulators page on how identify simulators.

The .AppBundle() and .DeviceIdentifier() must be configured. You can find the AppBundle in the DerivedData if your app was built using the command from Add an automation backend to your app.

Run a test

Start your tests from Visual Studio for Mac by selecting Unit Tests in the right side.
