Question

Erhalten des Fehlers als aufgeführt, während die Prüfung der LoginController

LoginController.js

'use strict'; 

/*Login Module Controllers */ 

angular.module('loginModule.controller', ['myApp.services', 'ngMd5']). 
controller('LoginController', ['$scope', '$location', 'ajaxService', 'userPersistenceService', 'md5', 'toast', 
function($scope, $location, ajaxService, userService, md5, toast) { 
    $scope.username = ''; 
    $scope.password = ''; 
    $scope.loginSuccess = ''; 
    $scope.login = function() { 
     ajaxService.ajaxPostReq({username: $scope.username, password: md5.createHash($scope.password || '')}, 'http://localhost:3000/user/auth', successFunction, errorFunction); 
    } 
    function successFunction(response) { 
     if(response.status == 'success') { 
      $scope.loginSuccess = true; 
      userService.setUser({userName: response.username, sessionId: response.sessionId}); 
      $location.path('/home'); 
      toast.showMessage('Successfully Logged In', response.status); 
     } else { 
      errorFunction(response); 
     } 
    } 
    function errorFunction(response) { 
     $scope.loginSuccess = false; 
     toast.showMessage(response.error, response.status); 
    } 
}]); 

LoginController.test.js

describe('Controller: LoginCtrl', function() { 
    angular.mock.module('loginModule.controller', []); 
    angular.mock.module('myApp.services', []); 

    var ctrl, ajaxService, $q; 
    beforeEach(inject(function($controller, _$q_, _ajaxService_){ 
     ctrl = $controller('LoginController'); 
     $q = _$q_; 
     ajaxService = _ajaxService_; 
    })); 
    describe('Login function', function() { 
     beforeEach(function(){ 
      var deferred = $q.defer(); 
      spyOn(ajaxService, 'ajaxPostReq').and.returnValue(deferred.promise); 
      ctrl.login(); 
     }); 

     it('should call ajaxService', function() { 
      expect(ajaxService.ajaxPostReq).toHaveBeenCalled(); 
     }); 
    }); 
}); 

Wie teste ichrichtig??? Mit dem Code, der wie oben geschrieben wird, erhalte ich den folgenden Fehler, während der Unit-Test.

Answer 1

Sie sind nicht bootstrapping Ihre module.

beforeEach(module('myApp')); 

Und auch überprüfen, ob Sie Ihren Dienst in karma.conf.js

aufgenommen haben
