Is there a way to use both a .testsettings and .runsettings file in Visual Studio 2013?

Question

I have an existing .testsettings file that is being used by Visual Studio for running tests.

We are starting to use the built-in code coverage tools with Visual Studio 2013 Ultimate.

Custom rules can be stored in a .runsettings file, and the project can be set to use that file in the Test > Test Settings > Select Test Settings menu.

Is there a way to use multiple settings files, since they have distinct purposes? Or do .testsettings and .runsettings both fulfill the same purpose?

Answer 1

I have determined that you can only use one of these. The MSDN Documentation lays out that .runsettings file is a newer version of .testsettings. .testsettings uses the older MSTest framework, where .runsettings uses the newer multi-engine provider framework with newer versions of Visual Studio.
