Not sure if its the same issue or not but I had to change from gulp-karma to just karma.

So the require statement I have:
var Server = require('karma').Server;

And the test task i have:
gulp.task('test', ['build-js'], function(done) {
Server.start({
configFile: __dirname + '/karma.config.js',
singleRun: true
}, function() {
done();
});
});
