TypeError：'undefined'不是函数（评估'mockBackend.expectPost（

Question

我试图用Karma和jasmine对angularjs控制器进行单元测试。

这是我的测试套件：

describe('Controllers', function(){
    var $scope, ctrl;
    beforeEach(module('curriculumModule'));
    describe('CreateCurriculumCtrl', function(){
        var mockBackend, location;
        beforeEach(inject(function($rootScope, $controller, _$httpBackend_, $location){
            mockBackend = _$httpBackend_;
            location = $location;
             $scope = $rootScope.$new();
             ctrl = $controller('CreateCurriculumCtrl', {
                    $scope: $scope
             });
        }));

        it('should save the curriculum', function(){
            mockBackend.expectPost('bignibou/curriculum/new');
            $scope.saveCurriculum();
            mockBackend.flush();
            expect(location.path()).toEqual("/");
        });

    });
});

这是业力开始的输出：

PhantomJS 1.9.2 (Linux) Controllers CreateCurriculumCtrl should save the curriculum FAILED
    TypeError: 'undefined' is not a function (evaluating 'mockBackend.expectPost('bignibou/curriculum/new')')
        at /home/julien/Documents/projects/site-garde-enfants/bignibou/karma/test/spec/curriculum.test.js:16
PhantomJS 1.9.2 (Linux): Executed 2 of 2 (1 FAILED) (0.203 secs / 0.023 secs)

我不明白为什么我得到这个错误，因为我在我的业力conf中正确包含了angular-mock.js文件：

// list of files / patterns to load in the browser
files: [
   '../src/main/webapp/js/libs/jquery-1.10.2.js',
   '../src/main/webapp/js/libs/angular.js',
   '../src/main/webapp/js/libs/bootstrap.js',
   '../src/main/webapp/js/plugins/angularui.select2.js',
   'test/vendor/angular-mocks.js',

  '../src/main/webapp/js/custom/curriculum.js',
  'test/spec/curriculum.test.js'      
],

有人可以帮忙吗？

编辑 ：这是我的控制器：

function CreateCurriculumCtrl($scope, $http, $location, select2Options){

    $scope.formData={};

    $scope.select2Options = select2Options; 

    $scope.saveCurriculum = function(){
        $http.post('bignibou/curriculum/new', $scope.formData).success(function(data) {
            if(data.status=="OK"){}
            if(data.status=="KO"){}
            $location.path("/");
        });
    };
}

Answer 1

改变第16行

从

mockBackend.expectPost('bignibou/curriculum/new');

至

mockBackend.expect('POST','bignibou/curriculum/new').respond({});

不知何故解决了这个问题......

编辑 ： expectPOST也会有效...只是一个错字：注意我使用的情况......

Answer 2

可能你的情况类似于：

var a = {};
a.b();

ab未定义，试图调用它会给你错误。

这里的第16行是$scope.saveCurriculum() ，是$scope.saveCurriculum undefined？
