No test found. Make sure that installed test discoverers & executors, platform & framework version settings are appropriate and try again

I am in the process of upgrading our existing solution to .Net 4.6.1 and have been unable to get our unit tests to run during a server build. Locally they run as expected and flipping the framework version back to .Net 4.5.1 makes them run again on the server.

I am getting the following error:

No test found. Make sure that installed test discoverers & executors, platform & framework version settings are appropriate and try again.

I have reproduced the problem in a simpler setup:

  • Solution with a single C# Unit Test project with two tests (one failing, one passing).
  • XAML build definition using the Default Template (TfvcTemplate.12.xaml)
  • TFS 2015 Update 1 XAML build server with Visual Studio Enterprise 2015 Update 1 installed (have six similar servers and all produce the same result)
Solution

  • This is a known issue for .Net 4.6 now.
