包括外部API时如何测试AngularJS？

Question

I'm using the SoundCloud JavaScript SDK with AngularJS, and trying to run Karma tests on it. I keep getting the error Error: [$injector:modulerr] Failed to instantiate module SoundcloudApp due to: ReferenceError: Can't find variable: SC when I run the tests.

The variable SC (provided by the SoundCloud API, when including the script) is used in an AngularJS service:

angular.module('SoundcloudApp').provider('SoundCloud', function() {
  SC.initialize({
    clientId: 'SeES8KzD8c44J9IU8djbVg'
  });

  this.$get = function($q) {
    return {
      getUser: function(id) {
        // returns user object with a given id

        var user = $q.defer(); 


        SC.get('/users/' + id, function (userData, err) {
          if (err) {
            user.reject(err.message);
          } else {
            user.resolve(userData);
          }
        });

        return user.promise;
      }
    };
  };
});

Should I just mock this service? How do I do that?

You can inject mocks into your service by using $provide.
