Report test results from Karma - Spectacular Test Runner for Javascript in xml format for the Karma Visual Studio test explorer adapter.
npm install karma-vs-reporter --save-dev
The adapter for test explorer in Visual Studio can be installed from Visual Studio Gallery.
For features and usage see Karma Visual Studio test explorer adapter.
At the moment the reporter only works properly with Jasmine tests. It should be relatively easy to add other frameworks. Pull requests are welcome.
