Unit testing AngularJS factories that have dependencies

There are two ways to accomplish something like this that I know of:

1. Use $provide and an anonymous module to inject the mock.
2. Inject the service you would like to mock and use jasmine’s spying ability to provide mock values.

The second option only works if you know exactly which methods your code under test will be calling on the injected service and you can easily mock them out. As you seem to be accessing a data property on the service (rather than a method) pursuing the first option might be best.

Using $provide would roughly look like this:

describe('myFactory', function () {
  // Load your module.
  beforeEach(module('myFactoryMod'));

  // Setup the mock service in an anonymous module.
  beforeEach(module(function ($provide) {
    $provide.value('oneOfMyOtherServicesStub', {
        someVariable: 1
    });
  }));

  it('can get an instance of my factory', inject(function(myFactory) {
    expect(myFactory).toBeDefined();
  }));
});
