Issues with executing basic unit test in Angular Js

THE ISSUE:

In an attempt to create unit tests for my Angular application, I set up a basic test app and wrote a simple unit test. However, the test is not functioning as expected.

APPLICATION CODE:

var app = angular.module( 'myApp', [] );

app.controller('InitCtrl', function( $scope, Person ) 
{
    $scope.test_person = Person.Person("Tom");
})

app.factory('Person', function(){
    return {
        Person: function(name){
            this.name = name;
            console.log ( name );
        }
    }               
})

UNIT TEST CODE:

describe('Person', function () {

  var Person;
  beforeEach(module('myApp'));
  beforeEach(inject(function (_Person_) {
    Person = _Person_;
  }));

  describe('Constructor', function () {

    it('assigns a name', function () {
      expect(new Person('Ben')).to.have.property('name', 'Ben');
    });

  });

});

ERROR MESSAGE DISPLAYED:

Upon running the test, I received the following error message:

PhantomJS 1.9.8 (Mac OS X 0.0.0) Person "before each" hook: workFn for "assigns a name" FAILED
Error: [$injector:modulerr] Failed to instantiate module myApp due to:
Error: [$injector:nomod] Module 'myApp' is not available! You either misspelled the module name or forgot to load it. If registering a module ensure that you specify the dependencies as the second argument.
http://errors.angularjs.org/1.4.4/$injector/nomod?p0=myApp

EFFORTS MADE TO RESOLVE:

I attempted using different syntax such as:

var app = angular.module( 'myApp' );

However, this did not solve the issue.

QUESTION AT HAND:

What could be incorrect in this simple test?
Is something missing from the application, or is there an error in the test script?

Thank you!

Answer №1

Chances are you forgot to include your app.js in your Karma configuration file:

module.exports = function(config) {
    config.set({
        basePath: '',    
        files: [
            '../../path/to/app.js',
         //...
