angularjs route unit testing

Question

As we see here in http://docs.angularjs.org/tutorial/step_07,

angular.module(\'phonecat\', []).
  config([\'$routeProvider\', function($routeProvider) {
  $r         


        

Answer 1

Combining the two previous answers, if you want to test the router as a black box that is successfully routing where it should (not the controller ets configs in themselves), whatever the routes might be:

// assuming the usual inject beforeEach for $route etc.
var expected = {};
it('should call the right controller for /phones route', function () { 
    expected.controller = $route.routes['/phones'].controller;
    $location.path('/phones');
    $rootScope.$digest();
    expect($route.current.controller).toBe(expected.controller);
});

it('should redirect to redirectUrl from any other route', function () {
    expected.path = $route.routes[null].redirectTo;
    $location.path('/wherever-wrong');
    $rootScope.$digest();
    expect($location.path()).toBe(expected.path);
});

Why not just assert the route object is configured correctly?

it('should map routes to controllers', function() {
  module('phonecat');

  inject(function($route) {

    expect($route.routes['/phones'].controller).toBe('PhoneListCtrl');
    expect($route.routes['/phones'].templateUrl).
      toEqual('partials/phone-list.html');

    expect($route.routes['/phones/:phoneId'].templateUrl).
      toEqual('partials/phone-detail.html');
    expect($route.routes['/phones/:phoneId'].controller).
      toEqual('PhoneDetailCtrl');

    // otherwise redirect to
    expect($route.routes[null].redirectTo).toEqual('/phones')
  });
});

I think you should be able to test the $routeProvider like this:

angular.module('phonecat', []).
  config(['$routeProvider', function($routeProvider) {
  $routeProvider.
      when('/phones', {templateUrl: 'partials/phone-list.html',   controller: PhoneListCtrl}).
      when('/phones/:phoneId', {templateUrl: 'partials/phone-detail.html', controller: PhoneDetailCtrl}).
      otherwise({redirectTo: '/phones'});
}]);


it('should test routeProvider', function() {
  module('phonecat');

  inject(function($route, $location, $rootScope) {

    expect($route.current).toBeUndefined();
    $location.path('/phones/1');
    $rootScope.$digest();

    expect($route.current.templateUrl).toBe('partials/phone-detail.html');
    expect($route.current.controller).toBe(PhoneDetailCtrl);

    $location.path('/otherwise');
    $rootScope.$digest();

    expect($location.path()).toBe('/phones/');
    expect($route.current.templateUrl).toEqual('partials/phone-list.html');
    expect($route.current.controller).toBe(PhoneListCtrl);

  });
});
