Could not mock the dependency explicitly asked to mock

[cmolina]

Hi. I am learning to use ng-improved testing, but when I try to inject the service I am testing

describe('$cart', function() {
  beforeEach(ModuleBuilder.forModules('web')
    .serviceWithMocksFor('$cart', '$api')
    .build());

  it('should return the number of elements in the cart', function() {
    inject(function($cart) {
      expect($cart.count).toBeNumber();
      expect($cart.count).toBeGreaterThan(-1);
    });
  });

I got the following error:

Error: [$injector:modulerr] Failed to instantiate module function ($provide, $filterProvider, $controllerProvider, $compileProvider, $animateProvider) due to:

I do not understand what I am doing wrong. Please help.

BTW, $api service is like:

app.service('$api', ['$resource', function($resource) {
  // stuffs like this.property = function() {...};
});

and $ service is like:

app.service('$cart', ['$localStorage', '$api', function CartService($localStorage, $api) {
  // ...
});

Currently ngImprovedTesting only mocks objects which have at least one object.
Could this be the case in your situation (although the // stuffs like this.property = function() {...}; appears to indicate otherwise)?
