类型错误：e.error 不是一个函数

要测试的JS代码：

function postSettings() {
        $.ajax(
            {
                type: "POST",
                url: EndPoints.Setup,
                data: frm_data,
                success: function (successData) {
                        ///// code is getting covered
                },
                error: function (errorData) {
                        ///// code is not getting covered
                }
            });
    }

茉莉花规格：

describe("Call Success path", function () {
            var ajaxSpy;
            beforeEach(function () {
                var MockEndPoints = global.EndPoints = {};
                MockEndPoints.SnmpSetup = "/mock/test/setup";
                ajaxSpy = spyOn($, "ajax").and.callFake(function (e) {
                    e.success(globalFakeData);
                });
            });
            it("Should populate settings", function () {
                Setup.postSettings();
                expect($.ajax).toHaveBeenCalledTimes(2);
            });
        });
        describe("Call Error path", function () {
            var ajaxSpy;
            beforeEach(function () {
                var MockEndPoints = global.EndPoints = {};
                MockEndPoints.SnmpSetup = "/mock/test/setup";
                ajaxSpy = spyOn($, "ajax").and.callFake(function (e) {
                    **e.error; // No error but the path is not covered**
                    **e.error(globalFakeData); // throws the above error**
                });
            });
            it("Should populate settings", function () {
                Setup.postSettings();
                expect($.ajax).toHaveBeenCalledTimes(1);
            }); 
        });

谢谢。
