[AngularJS] Unit Testing with AngularJS $httpBackend problems

[Shawn Shaw]

I am frustrated with my testing efforts thus far and am hoping someone can 
help.

I currently have a controller, LoginController, which depends on an 
authenticationSvc.

Within the LoginController, there is a $scope.login function which passes a 
user object off to the authenticationSvc.  That is the only code in the 
LoginController.

I'm trying to verify that a 200 response is returned from a successful 
login.  That's all I'm really trying to do, although eventually I would 
like to write an integration test that actually does login to the app and 
log out programmatically.  Different topic, but if there are any good tools 
for that, I would be very interested.

But back to the original problem.  I'm using karma as my testing 
environment, mocha as my framework, and should as my assertion library.

Currently I can get sanity "this should pass" and "this should fail" tests 
operating correctly.

My very simple code is from a blog post 
<http://jasonmore.net/unit-testing-http-service-angular-js/>, but has been 
modified to call my authenticationSvc, and is as follows:

describe('with httpBackend', function() {
    beforeEach(inject(function($controller, $rootScope, $httpBackend) {
      $scope = $rootScope.$new();
      
      $httpBackend.when('POST', '/login')
        .respond({things: 'and stuff'});

      MainCtrl = $controller('LoginController', { $scope: $scope });
      $httpBackend.flush();
    }));
    
    it('should set data to "things and stuff"', function() {
      expect($scope.data).toEqual({
        things: 'and stuff'
      });
    });
  });


However, even though my karma.config.js file includes the declaration file 
of my LoginController, I'm experiencing the following error:

Error: the object { "message": "[ng:areq] Argument 'LoginController' is not 
a function, got undefined

What am I missing?  Shouldn't this be easier?

*bangs head against nearest wall*

Thanks for any help you can offer.

Cheers!

Shawn
