How to remove Chutzpah from project to not show result in test explorer?

I have made a demo project to learn Chutzpah and installed it for VS2013. Now in my another project I don't use Chutzpah but Karma for testing Angularjs test cases, but still test Explorer shows Angularjs unit tests as failed tests, how can i remove angularjs test cases from test explorer? I only want backend Csharp Unit tests to run in test explorer.

Please help me soon...
