In Evolve 2016 Visual studio team services (VSTS) team has made an awesome presentation about managing Xamarin apps with VSTS . This talk inspired me to try this new experience. In this post we are going to configure build pipeline for Xamarin iOS and will add to that the integration with HockeyApp and Xamarin Test Cloud. Steps

Configure build agent  Microsoft has rebuilt VSTS build and release agent. This will be replacing/combining the existing closed source windows build agent and the existing xplat agent supported on Windows, OSX, Ubuntu and Red Hat written for the .NET Core CLR as one code base in C#. There is a prerequisite  for VSTS agent which is .Net core. The instruction below will go through how we can install it.

Installing .Net Core

  1. brew update
  2. brew install openssl
  3. brew link –force openssl

Check here if you have installation issues.

Installing VSTS agent for Mac

  1. We need to add VSTS build account to the proper roles, please follow steps written here.
  2. Follow instruction here for downloading /installing VSTS agent.
  3. If you want to run agent as a service, follow following steps:
    1. Navigate to where you have extracted agent and then run the command below.
    2. ./svc.sh install (will configure agent as service)
    3. ./svc.sh start (will start agent)

Agent up and running   Create a new build definition for our app

We are going to configure VSTS build pipeline for our app as below:

[gallery ids=“248,249,250,251,254,252,253” columns=“1” size=“full”] I believe you maybe now asking why our build is failing. After investigating this issue, it seems there is a bug  in the build definition because locally build is succeeding. It turns out that msbuild is trying to build our portable class library against iPhone configuration not AnyCpu, which is not there and this was causing build to fail.

Build Error:

 /Library/Frameworks/Mono.framework/Versions/4.4.1/lib/mono/xbuild/12.0/bin/Microsoft.Common.targets: error : ‘OutputPath’ property is not set for this project. Usually this is caused by invalid Configuration/Platform combination. Original values: Configuration: Release Platform: iPhone.

Hooray green build

Xamarin Test Cloud In this section we are going to publish our app to Xamarin Test Cloud and run UI automation tests. VSTS made this task very easy, we just need to add Xamarin test cloud task as following. [gallery ids=“353,378” columns=“1” size=“large”] Publishing app to  HockeyApp Finally  we are going to publish our app to HockeyApp. HockeyApp is going to be our store, which means testers can download new versions from the app through the HockeyApp application. HockeyApp is doing a great job here by easing mobile DevOps experience. So for configuring build pipeline check the steps below. [gallery ids=“348,347,354,351,349” columns=“1” size=“large”] Well done VSTS team you have done great job here. I’ve done the same pipeline before with Bamboo and Fake  and I can tell you that experience wasn’t that good. But today it’s very easy using VSTS.   References
