Team Foundation Server 2015–Enable NUnit tests for new Build system

I’m working on replacing the existing build system we use based on XAML Workflow by the new build system introduced in TFS 2015. So far, I really like the experience. Customizing became a lot easier than it was before…

However one of the things I noticed that no Test Results were collected.

 

I opened up the Test Assemblies Step in the build process(click on the step in the Build Results).

There I could see that the vstest.console.exe was invoked but that no tests were discovered.image

The reason is that I’m using NUnit and therefore a test adapter should be installed and loaded on the build server.

Enable NUnit Test Adapter for TFS Build

To enable the NUnit Test Adapter, you have multiple options:

Option 1- Use the NUnit Test Adapter DLL’s

  • Log in to your build server
  • Download the NUnit Test Adapter for Visual Studio from the Visual Studio gallery: https://visualstudiogallery.msdn.microsoft.com/6ab922d0-21c0-4f06-ab5f-4ecd1fe7175d
  • Extract the VSIX file(don’t install it!) and copy the DLL’s to the following folder
    • C:\Program Files (x86)\Microsoft Visual Studio 14.0\Common7\IDE\CommonExtensions\Microsoft\TestWindow\Extensions
  • After installation,  go back to the TFS web portal and open the Team Project where you want to configure the build for
  • Go to the Build tab
  • Queue a new build

Option 2 – Use the NUnit Test Adapter Visual Studio Extension

  • Log in to your build server.
    • Remark: When you use this option, it’s important the account you use to log in is the same account that is used to run the tests
  • Download the NUnit Test Adapter for Visual Studio from the Visual Studio gallery: https://visualstudiogallery.msdn.microsoft.com/6ab922d0-21c0-4f06-ab5f-4ecd1fe7175d
  • Install the VSIX file
  • After installation,  go back to the TFS web portal and open the Team Project where you want to configure the build for
  • Go to the Build tab
  • Right-click on the build definition and choose Edit…
  • Select the Visual Studio Test step
  • On the right, expand the Advanced section
  • Add the ‘/UseVsixExtensions:true’ in the Other console options field

  • Save the edited build definition
  • Queue a new build

Option 3  - Include the NUnit Test Adapter using NuGet

  • Open the solution you want to build in Visual Studio
  • Add the NUnit Test Adapter NuGet package(https://www.nuget.org/packages/NUnitTestAdapter/) to your solution
  • Browse to the TFS web portal and open the Team Project where you want to configure the build for
  • Go to the Build tab
  • Right-click on the build definition and choose Edit…
  • Select the Visual Studio Test step
  • On the right, expand the Advanced section
  • Add the ‘$(Build.SourcesDirectory)\packages’ in the Path to Custom Test Adapters field

  • Save the edited build definition
  • Queue a new build

Thanks for listing out all the options. The NuGet option works for me. Initially, I was trying to use the VS Extension option. It didn't work and I think it is because the TFS is using an agent pool with multiple build machines.
