Getting Test Results in Azure DevOps Pipelines

Referencing the Visual Studio test runner

• Using NuGet Package Manager (or Package Manager Console), add xunit.runner.visualstudio to at least one of your test projects. install-package xunit.runner.visualstudio

Configure Azure DevOps

• Add a build step of type Visual Studio Test.

These instructions are written for Version 2.* of the Visual Studio Test task.

Locate test assemblies

• Under Test selection/Test files, point to your generated test assemblies, for example:

  **\bin\$(BuildConfiguration)\**\*test*.dll
  !**\obj\**
  !**\xunit.runner.visualstudio.testadapter.dll
  !**\xunit.runner.visualstudio.dotnetcore.testadapter.dll
  

  (The third and fourth line excludes the xUnit test adapters from being considered a test assembly.) Note: it is important to make sure the file matching pattern is valid. testVerAssemblyVer2 must be expressed with newlines. vsts-doc issue 1580

Enable Code Coverage (optional)

• Select the Execution Options/Code Coverage Enabled checkbox.
• Add /InIsolation under Execution options/Other console options. (This will suppress a warning otherwise generated.)

Viewing the results

After a successful build, the test results are available on the main view of the build. It should look something like this:

Comments

• You no longer need to manually configure the test adapter path, because NuGet restored test adapters are automatically searched for.

• Sometimes you get this error one or many times Warning: System.AppDomainUnloadedException: Attempted to access an unloaded AppDomain. This can happen if the test(s) started a thread but did not stop it. Make sure that all the threads started by the test(s) are stopped before completion. It is not related to Azure DevOps and does not affect the results. For more information, see xUnit Issue 490 and MS Connect.
