I build and test Xamarin and Xamarin Test Cloud using Visual Studio Team Services. It works fine. However, I had some pitfalls for building/testing it. I'd like to share these pitfalls and solutions.
Xamarin Project: (Android(Xaml)/iOS(Forms))
IDE : Visual Studio 2015 Update 3 (Android), Xamarin Studio for Mac (iOS)
Build Agent: Hosted(Android), MacOSX + VSTS Build Agent(iOS)
VSTS Build Definitions
1. App does not contain permission (Android)
App does not contain permission 'android.permission.INTERNET', please include this permission
You just add this permission into AndroidManifest.xml
2. Unable to find the nunit.framework.dll in the assembly directory. (Android)
You need to include the dll in your assembly.
Using Visual Studio
References > nunit.framework (Right click) > Properties > Copy Local > True
3. Unable to find the unuit.framework.dll in the assembly directory. (iOS)
The cause is the same as Android's one. However, it might be confusing. If you use Xamarin Studio and try to change "Local Copy for it" However, it looks already "True." But it is actually "False" as default. You need to edit *.csproj file. See the example below.
Unable to find the nunit.framework.dll in the assembly directory. In Xamarin Studio you may have to right-click on the nunit.framework reference and choose Local Copy for it to be included in the output directory.
4. The .ipa file does not seem to be linked with Calabash framework.
If you want to enable Calabash, just add this line into your code. Then the compiler include
See This page.
Also, you need to edit your csproj file as well. You need to include ENABLE_TEST_CLOUD constants in the DefineConstants tag
I configure it for Release. You need to consider this part when you use in production.
You can build and test Xamarin project using VSTS. Enjoy coding!
