bower_components/angular/angular.min.js should be added to the core/gulp/karma.js in the attribute files, as well as a reference to all source files: '/src//*'

Forget that first comment. Better is to let the core/gulp/karma.js reference to the karma.config.js file that resides in the angus.AppPath. The user can then edit and customize the config file for karma.

karma.start({
configFile: angus.AppPath + '/karma.conf.js',
singleRun: true
})
