Hi @Teige, Connor,
Welcome to Microsoft Q&A!
You can try to use the vstest.console.exe to logs the test results to a .trx file.
By default, the vstest.console.exe file is located in the C:\Program Files (x86)\Microsoft Visual Studio 14.0\Common7\IDE\CommonExtensions\Microsoft\TestWindow folder.
Please open the developer command prompt Visual Studio 2015 and run the following command:
vstest.console.exe "YourTestProjectPath\YourTestProject\bin\<DebugorRelease>\TestProject.dll" /Logger:trx
Then, you can find the test results in the location:
C:\Program Files (x86)\Microsoft Visual Studio 14.0\Common7\IDE\CommonExtensions\Microsoft\TestWindow\TestResults
Sincerely,
Anna
