Encountering an undefined error in Angular while running Karma-Jasmine tests

I am struggling with testing using Karma-jasmine to run my tests as I keep encountering errors.

Here is a snippet from my karma.conf.js file:

files: [
  'test/*Spec.js',
  'app/js/*.js'
],

When I run the test, I receive the following errors in the command line:

Chrome 39.0.2171 (Windows 7) ERROR
  Uncaught TypeError: Cannot read property 'module' of undefined
  at D:/Test_Samples/WebContent/MyTest/app/js/angular-route.js:24


Firefox 34.0.0 (Windows 7) ERROR
  TypeError: angular is undefined
  at D:/Test_Samples/WebContent/MyTest/app/js/angular-route.js:24


IE 8.0.0 (Windows 7) ERROR
  'undefined' is null or not an object
  at D:/Test_Samples/WebContent/MyTest/app/js/angular-route.js:24

The error seems to be arising from line 24 of angular-route.js:

/* global -ngRouteModule */
var ngRouteModule = angular.module('ngRoute', ['ng']).provider('$route', $RouteProvider),
    $routeMinErr = angular.$$minErr('ngRoute');

Answer №1

To effectively run your tests, make sure to import angular and angular-stuff beforehand. Here's an example of the configuration I currently use:

files: [
    {pattern: 'src/main/webapp/static/libs/jquery/dist/jquery.js', watch: false},
    {pattern: 'src/main/webapp/static/libs/angular/angular.js', watch: false},
    {pattern: 'src/main/webapp/static/libs/angular-resource/angular-resource.js', watch: false},
    {pattern: 'src/main/webapp/static/libs/angular-mocks/angular-mocks.js', watch: false},
    {pattern: 'src/main/webapp/static/libs/angular-ngkit/js/ngkit.js', watch: false},
    'src/main/webapp/static/templates/angular/*.html',
    'src/main/webapp/static/js/angular/**/*.js',
    'src/test/js/spec/angular/*.js'
 ],

Remember, it's a good practice to disable watching for libraries (watch: false) as these files typically remain static during development!

Furthermore, don't forget to set the "basePath" property to ensure that all paths are resolved correctly from the specified root directory!

It is crucial to include the angular.js file before any other angular files in your project setup. Double-check your config file with the one provided during karma installation for accuracy. Visit this page for more information:
