UI Router Extras breaks my unit tests with unexpected results error?

Question

QUESTION:

- Why are my tests failing when ui-router-extras (not normal ui-router) is install?

- How can I use ui-router-extras and still have my tests pass?

---

If you want to install this quickly use yeoman + angular-fullstack-generator + bower install ui-router-extras

I found a similar issue with normal ui-router.

• Luckially, ui-router normal works just fine with my testing.
• After installing ui-router-extras I get an ERROR

If I uninstall ui-router.extras it this test passes just fine:

UPDATED for beforeEach module of $urlRouterProvider TEST Heres my test:

'use strict';

describe('Controller: MainCtrl', function () {

  // load the controller's module
  beforeEach(module('morningharwoodApp'));
  beforeEach(module('socketMock'));

  var MainCtrl,
      scope,
      $httpBackend;

  // Initialize the controller and a mock scope


  beforeEach(
    inject( function (_$httpBackend_, $controller, $rootScope) {
      $httpBackend = _$httpBackend_;
      $httpBackend.expectGET('/api/things')
        .respond(['HTML5 Boilerplate', 'AngularJS', 'Karma', 'Express']);

      scope = $rootScope.$new();
      MainCtrl = $controller('MainCtrl', {
        $scope: scope
      });
    }),
    module(function ($urlRouterProvider) {
      $urlRouterProvider.otherwise( function(){ return false; });
    })
  );



  it('should attach a list of things to the scope', function () {
    $httpBackend.flush();
    expect(scope.awesomeThings.length).toBe(4);
  });
});

Here's my karma.conf

module.exports = function(config) {
  config.set({
    // base path, that will be used to resolve files and exclude
    basePath: '',

Answer 1

This might be a result of some component having a dependency on $state in which case $state will be instantiated and default route will be executed. This is why a template of one of your controllers main.html is being fetched.

To bypass this, replace go() and transitionTo() of $state methods with dummies:

beforeEach( inject( function ( _$state_ ) {
        state = _$state_;
        spyOn( state, 'go' );
        spyOn( state, 'transitionTo' );
    } ) );

Answer 2

Here's an alternate solution that doesn't nuke ui-router's transitionTo function.

---

First, the failing scenario can be reproduced by following these steps:

npm install yo generator-angular-fullstack;
yo angular-fullstack

Inject $state service by adding this line to client/app/app.js:

angular.module("yoAppName").run(function($state) {});

At this point, invoking grunt karma reports the Unexpected request: GET app/main/main.html because UI-Router is bootstrapped and tries to load the default route, which requests the route's template.

---

To address this, tell UI-Router to delay synchronizing the URL to the state, so we don't load the default route. In the controller spec, add $urlRouterProvider.deferIntercept(); to your test init code:

beforeEach(module('uiRouterExtrasKarmaBugApp'));
// Add the following line
beforeEach(module(function($urlRouterProvider) { $urlRouterProvider.deferIntercept(); }));
