我想在 AngularJS 应用程序中测试控制器

Question

我无法解决依赖关系。

例如测试这个控制器时：

var MyApp = angular.module("MyApp");

MyApp.controller("GameController", ["$scope", "$interval" , "MY_CONST" , "Auth" , "CustomActionService" , "GamesFactory", "GameFactory", "$location", function($scope, $interval , MY_CONST , Auth , CustomActionService , GamesFactory, GameFactory, $location){

    $scope.testVar = "test text";

    $scope.indexGames = function(){
        GamesFactory.query({}, function(data) {
                $scope.games = data;
            }, function(error) {
                console.log(error);
            }
        );
    }

    $scope.deleteGame = function(game){
        if(confirm("Are you sure?")){
            GameFactory.delete({id: game.id},
            function(){
                $scope.indexGames();
            });
        }
    };

    $scope.createGame = function(){
        GamesFactory.create({game: $scope.newGame}, function(data, $scope){
            $location.path(MY_CONST.GAMES_PATH + data.id);
        }, function(error){
            console.log(error);
        });
    };

    $scope.joinGame = function(game){
        CustomActionService.join({id: game.id , action: MY_CONST.ACTION_UPDATE}, function(){
            $location.path(MY_CONST.GAMES_PATH + game.id);
        });
    };

    $scope.showGame = function(game) {
        $location.path(MY_CONST.GAMES_PATH + game.id);
    };

    $scope.resolveUser();
    $scope.indexGames();

    $interval(function(){
        setTimeout(function() {
            $scope.$apply(function() {
                $scope.indexGames();
            });
        }, MY_CONST.TIMEOUT);
    }, MY_CONST.INTERVAL);
}]);

我运行一个测试：

'use strict';

/* jasmine specs for controllers go here */
describe('MyApp controllers', function() {

    var TEST_GAMES = {
        "id": 1,
        "state": "expactation_second_player",

            "player_cards": [],
            "cards_count": null,
            "created_at": null,
            "updated_at": null
        },
        "defender": {
            "id": null,
            "user_id": null,
            "game_id": null,
            "player_cards": [],
            "cards_count": null,
            "created_at": null,
            "updated_at": null
        },
        "mover": {
            "id": null,
            "user_id": null,

            "cards_count": null,

        },
        "name": "qwe",
        "description": "qweqwe",
        "created_at": "2015-01-19T16:02:12.133Z",
        "updated_at": "2015-01-19T16:02:12.783Z"
    };

    beforeEach(function() {
        angular.mock.module('ngResource', []);
        angular.mock.module('ngRoute', []);
        angular.mock.module('Devise', []);
        module('MyApp', ['ngResource', 'ngRoute', 'Devise']);
    });

    describe('GameCtrl', function() {
        var scope, $httpBackend, ctrl;


        beforeEach(inject(function(_$httpBackend_, $rootScope, $controller) {

        }));


        it('should to create "testVar" variable with value "test text"', function() {

        });
    });
});

测试失败并出现错误：

**我认为问题如下：

beforeEach(inject(function(_$httpBackend_, $rootScope, $controller) {

}));

我想，你忘记在模块中添加依赖项了。试试这个

var MyApp = angular.module("MyApp",[]);

我想在 AngularJS 应用程序中测试控制器

I want to test controllers in AngularJS app

angularjs

unit-testing

karma-runner

karma-jasmine
