What is the best practice for unit testing AngularJS modules kept in a self executable anonymous funcitons

Question

I am looking for suggestions about the best practice around here in this scenario. I have created an angularjs SPA application and looking for building a unit test framework for it. I observed that I am not able to get the app object of the module because I have included all my JS files in self executing anonymous functions.

Here is my module for the application

(function () {
    'use strict';
     var app = angular.module('app', []);
})();

Here is my unit test file to load app module

describe("App Model Load -> ", function () {
    beforeEach(module("app"));
    it("Check App object", function () {
        expect(app).toBeDefined();
    });
});

I found resolutions like using a namespace on the top and binding the app variable to the namespace, but it is no different from opening up the app variable globally. Any thoughts?

You shouldn't need to write a test to verify that the app object exists. You should only be testing the sub-modules that are added to the app object. — tennisgent, Jun 24 '14 at 20:32
Yes, I got that but I just wrote it for explaining the scenario, it errors out in beforeEach step, in the above scenario. — Saikiran Sheshagiri, Jun 24 '14 at 20:34
If you call angular.module by specifying only first argument then, if module exist, you can retrieve it. In your unit test try this: var app = angular.module('app');expect(app).toBeDefined(); — Yevgeniy.Chernobrivets, Jun 24 '14 at 20:36
Hmmm this certainly works but I want to mock the app object here and not reinitialize it. Also, when I try var app then it cetainly comes as defined but I am not able to mock it — Saikiran Sheshagiri, Jun 24 '14 at 20:42
What do you mean by "mock module"? As Saikiran Sheshagiri mentioned you should mock parts of module (like services) not the whole module. Module is only a container. — Yevgeniy.Chernobrivets, Jun 24 '14 at 20:54
