从 Karma 和 Jasmine 测试调用控制器函数

Call a controller function from Karma and Jasmine testing

本文关键字：调用 控制器 函数 测试 Jasmine Karma      更新时间：2023-09-26

这是我的角度控制器：- 

 angular.module('authoring-controllers', []).
        controller('NavCtrl', function($scope, $location, BasketNavigationService) {
$scope.test= function() {
                $scope.testVar = BasketNavigationService.showBasketList();
            };
        });

测试类

describe('NavCtrl', function() {
    var scope, $location, createController;
    beforeEach(inject(function ($rootScope, $controller, _$location_) {
        $location = _$location_;
        scope = $rootScope.$new();
        createController = function() {
            return $controller('NavCtrl', {
                '$scope': scope
            });
        };
    }));
    it('should create $scope.testVar when calling test', 
        function() {
          expect(scope.testVar).toBeUndefined();
          scope.test();
          expect(scope.testVar).toBeDefined();
      });
});

当我运行该测试用例时出现错误：- scope.test（） 未定义。

如果我从控制器中删除了篮子导航服务功能，那么它就可以工作了。

请帮助我解决该业力测试用例。

这是工作演示，希望对您有所帮助。问题在于注入依赖项。

//--- CODE --------------------------
(function(angular) {
  // Create module
  var myApp = angular.module('myApp', []);
  // Controller which counts changes to its "name" member
  myApp.controller('MyCtrl', ['$scope', 'BasketNavigationService',
    function($scope, BasketNavigationService) {
      $scope.test = function() {
        $scope.testVar = BasketNavigationService.showBasketList();;
      };
    }
  ]);
})(angular);
// ---SPECS-------------------------
describe('myApp', function() {
  var scope,
    controller;
  beforeEach(function() {
    module('myApp');
  });
  describe('MyCtrl', function() {
    beforeEach(inject(function($rootScope, $controller) {
      scope = $rootScope.$new();
      controller = $controller('MyCtrl', {
        '$scope': scope,
        'BasketNavigationService': {
          showBasketList: function() {
            return null;
          }
        }
      });
    }));
    it('should create $scope.testVar when calling test',
      function() {
        expect(scope.testVar).toBeUndefined();
        scope.test();
        //     scope.$digest();
        expect(scope.testVar).toBeDefined();
      });
  });
});
// --- Runner -------------------------
(function() {
  var jasmineEnv = jasmine.getEnv();
  jasmineEnv.updateInterval = 1000;
  var htmlReporter = new jasmine.HtmlReporter();
  jasmineEnv.addReporter(htmlReporter);
  jasmineEnv.specFilter = function(spec) {
    return htmlReporter.specFilter(spec);
  };
  var currentWindowOnload = window.onload;
  window.onload = function() {
    if (currentWindowOnload) {
      currentWindowOnload();
    }
    execJasmine();
  };
  function execJasmine() {
    jasmineEnv.execute();
  }
})();

请将createController设置更改为：

 createController = function() {
            return $controller('NavCtrl', {
                '$scope': scope,
                '$location':$location,
                'BasketNavigationService':{showBasketList: function(){return 'test'} }
            });
        };

您没有注入所有依赖项。我注射了假BasketNavigationService，你可以注射真。

你试过运行createController();吗？我不认为你的NavCtrl控制器被嘲笑。
