Injecting custom factory in jasmine test - angularjs

Question

I tried to inject a factory to my controller in jasmine test like in
Unit testing AngularJS factories that have dependencies
When I $provide a factory in the test, I would expect the controller to use the provided factory. But the console.log still prints 'real value'. I don't get it.
var app = angular.module('mod', []);
app.factory('factoryA', [
function () {
return "real value";
}
]);
app.controller('myController', ['factoryA',
function (factoryA) {
console.log(factoryA);
}
]);
describe("test", function() {
var $scope, $controller, $httpBackend;
var app;
beforeEach(function() {
module(function($provide) {
$provide.factory('factoryA', function () { return "fake value"; });
});
app = module("mod");
inject(function (_$controller_, _$httpBackend_, $rootScope) {
$httpBackend = _$httpBackend_;
$scope = $rootScope.$new();
$controller = _$controller_;
});
});
it("works", function() {
$controller("myController", { '$scope': $scope });
});
});

You would need to get the $provider from the module mod so pass module name as first argument so that it overrides the factoryA definition that was created originally. Or load the module - module("mod") - before setting up mock.
module('mod', function($provide) {
$provide.factory('factoryA', function () { return "fake value"; });
});
Another way it to create mocks and pass it to the controller creation.
describe("test", function() {
var $scope, $controller, $httpBackend;
var app, factoryA;
beforeEach(function() {
module(mod);
inject(function (_$controller_, _$httpBackend_, $rootScope) {
//...Your code
//Mock factory
factoryA = jasmine.createSpy('factoryA');
factoryA.and.returnValue("fake value");
});
});
it("works", function() {
//Pass the mock factory
$controller("myController", { '$scope': $scope, factoryA:factoryA });
});
});
