How do you mock a service in AngularJS when unit t

Question

Let's say I have a service shop that depends on two stateful services schedule and warehouse. How do I inject different versions of schedule and warehose into shop for unit testing?

Here's my service:

angular.module('myModule').service('shop', function(schedule, warehouse) {
    return {
        canSellSweets : function(numRequiredSweets){
             return schedule.isShopOpen()
                 && (warehouse.numAvailableSweets() > numRequiredSweets);
        }
    }
});

Here are my mocks:

var mockSchedule = {
    isShopOpen : function() {return true}
}
var mockWarehouse = {
    numAvailableSweets: function(){return 10};
}

Here are my tests:

expect(shop.canSellSweets(5)).toBe(true);
expect(shop.canSellSweets(20)).toBe(false);

Answer 1

Improving upon Atilla's answer and in direct answer to KevSheedy's comment, in the context of module('myApplicationModule') you would do the following:

beforeEach(module('myApplicationModule', function ($provide) {
  $provide.value('schedule', mockSchedule);
}));

Answer 2

With CoffeeScript I run in some issues so I use null at the end:

beforeEach ->
  module ($provide) ->
    $provide.value 'someService',
      mockyStuff:
        value : 'AWESOME'
    null
