I have codedUI and unit tests in my solution. Solution and the unit tests are successfully building in TFS 2017. CodedUI tests fail. I get an error.
Failed to initialize the unit test extension 'urn:CodedUITest': A unit test extension is not registered for the following attribute: Microsoft.VisualStudio.TestTools.UITesting.CodedUITestAttribute.
All the tests successfully pass in my local machine. What configuration am I missing in my build process?
kindly, help!.
According to the error info, seems the issue should more related to build agent Environment setting. Make sure you have Visual Studio and Coded UI features installed on the build agent. You could double check this by remote to the build agent and manually run Code UI in the agent machine instead of through TFS build.
If you are using Nuget Visual Studio Test Platform Installer , this is not support for now, take a look at the similar issue: VSTS build release agent unable to run Coded UI tests when using the Nuget VsTest platform
Currently Coded UI and UWP tests not support with VSTest platform nuget package. /cc @PBoraMSFT for blog/doc and timeline for support.
