Javascript Question

Testing service with angular-mocks/jasmine - TypeError: undefined is not an object

Im trying to test a simple service in my angular app, using jasmine/karma/phantomJS.

jasmine version: 2.4.1
angular/angular-mocks: 1.5.7
phantomJS: 2.1.1

QueryParameters.service.tests.js : (QueryParameters.service.js is part of the app.service module, and is actually a factory, not a service)

describe('myApp.QueryParametersService', function() {

var QueryParametersService;

beforeEach(module('myApp'));
beforeEach(module('app.service'));
beforeEach(inject(function ($injector) {
QueryParametersService = $injector.get('QueryParametersService');
}));

var testObject = {
name : 'Hans',
age : '27'
};

it('Should output correct querystrings', function() {
expect(QueryParametersService.toQueryParams(testObject)).toBe('?name=Hans&age=27');
});

});


QueryParametersService.js:

(function() {
'use strict';

angular.module('app.service')
.factory('QueryParametersService', QueryParametersService);

QueryParametersService.$inject = [];

function QueryParametersService() {

var service = {
toQueryParams : toQueryParams
};

return service;

function toQueryParams(queryObject) {
<removed code here>
}
}
})();


In Gruntfile.js:

karma: {
unit: {
options: {
frameworks: ['jasmine'],
singleRun: true,
browsers: ['PhantomJS'],
files: [
'<%= yeoman.client %>/bower_components/angular/angular.js',
'<%= yeoman.client %>/bower_components/angular-mocks/angular-mocks.js',
'<%= yeoman.client %>/app/app.js',
'<%= yeoman.client %>/app/filters/filter.module.js',
'<%= yeoman.client %>/app/directives/directive.module.js',
'<%= yeoman.client %>/app/services/service.module.js',
'<%= yeoman.client %>/app/services/tests/*.js'
]
}
}
}


my main module (in app.js) is declared like this:

angular.module('myApp', [
'angular-thumbnails',
'angularUtils.directives.dirPagination',
'app.directive',
'app.filter',
'app.service',
'color.picker',
'ngCookies',
'ngFileUpload',
'ngImgCrop',
'ngMaterial',
'ngMessages',
'ngResource',
'ngSanitize',
'ui.router',
'validation.match',
])


The error im getting when running the tests:

PhantomJS 2.1.1 (Mac OS X 0.0.0) myApp.QueryParametersService Should output correct querystrings FAILED

Where am I going wrong here?

Answer

As @jchen86 pointed out, QueryParametersService.js wasnt included in config (I thought it woul be included when i included the whole service module). Solved by changing the gruntfile to include all js files in the service folder:

'<%= yeoman.client %>/app/services/*.js'
