We are in the process of upgrading from TFS to 2012 to TFS 2015, however the test team is ready to move to Visual Studio 2015 automated tests. They currently have a number of VS 2012 automated tests they run in VS 2012 agents/controllers.
Given the configuration changes in Visual Studio automated test controllers/agents in Visual Studio 2015 (compared with VS 2012), will automated tests created in Visual Studio 2015 work with TFS 2012?
I know VS 2015 no longer utilizes test 'controllers' but relies on TFS 2015 to control automated tests. If I read this TFS compatibility article correctly: When you are using TFS 2013, you must use VS 2013 test controllers and agents. Or to put it another way, you cannot use VS Test agents against TFS 2013. Is this correct? And can I assume the same is correct for 2012?
To ask another way: If the test team has to use VS 2015 for automated tests now, can this be done without TFS 2015?
