Having trouble loading a module during AngularJS unit testing

I have been working on writing unit tests for my angularJS 1.4.x app's Services and Controllers. The issue I am facing is that all our controllers and services are declared within modules, as shown in the example below under "MyApp".

module MyApp {

        'user strict';

         export class MyService {
              public static $inject = [
                '$http',
                '$rootScope',
                'library'
              ];
              constructor(private $rootScope:any,
                        private $http:ng.IHttpService,
                        private library:lib.Library) {}

              // some methods...
         }
    }
    

However, when attempting to require this file in my test.js file, I encounter the following error:

SyntaxError: Unexpected token, expected ";" (1:7)
    

Below is a snippet from my test file:


    require('../../../node_modules/angular/angular.min.js');
    require('../../../node_modules/angular-mocks/angular-mocks.js');    
    require('../ts/MyService.ts');

    describe('Testing MyService', function(){

        beforeEach(
            angular.mock.module('app')
        );

        var service;

        beforeEach(inject(function(myService) {
            service = myService;
        }));

        it('Adding 1 + 1 should equal 2', function(){
            var result = service.addTwoNumbers(1,1);
            expect(result).toEqual(2);
        });       
    });

This situation appears to involve an Application written in TypeScript, whereas the test is authored in JavaScript.

If you execute the test (written in JavaScript) and attempt to access components written in TypeScript, they will not be able to be interpreted by the JavaScript parser.

To resolve this issue, ensure that you compile your TypeScript code into JavaScript and then incorporate the resulting files (.js) into your test, rather than using the original TypeScript source files (.ts).
