Mocking Cookies with Angular

Your unit tests need not have to create a mock $cookieStore and essentially re-implement its functionality. You can use Jasmine's spyOn function to create a spy object and return values.

Create a stub object

var cookieStoreStub = {};

Set up your spy object before creating the controller

spyOn(cookieStoreStub, 'get').and.returnValue('TEST'); //Valid syntax in Jasmine 2.0+. 1.3 uses andReturnValue()mainCtrl = $controller('MainCtrl', { ...  $cookieStore: cookieStoreStub }

Write unit tests for the scenario in which cookie is available

describe('If the cookie already exists', function() {    it('Should not retrieve UUID from server', function() {        console.log(cookieStore.get('myUUID')); //Returns TEST, regardless of 'key'        expect(userService.getNewUUID).not.toHaveBeenCalled();    });});

Note: If you'd like to test multiple cookieStore.get() scenarios, you might want to move the creation of the controller into a beforeEach() inside the describe() block. This allows you to call spyOn() and return a value appropriate for the describe block.
