这是我的 Controller :
export class testController {
static $inject: string[] = ["testService", "$mdDialog", "$state"];
constructor(public _testService: services.testService, private _mdDialog: any, private _$state: any) {
this.isCurrentlyEditing = false;
this.activate();
}
}
这是我的 单元测试 为了那个原因:
import {test as service} from './test.service';
import {test as ctrl} from './test.controller';
export function main() {
describe("testController", () => {
var mdDialog: angular.material.IDialogService;
var state: ng.ui.IStateService;
var testService: any;
var controller: any;
beforeEach(function () {
angular.mock.module('comp.modules.addField');
});
beforeEach(function () {
testService = {
showCLULayer: () => { }
};
});
beforeEach(module('comp'));
beforeEach(inject(($injector: any) => {
mdDialog = $injector.get('$mdDialog');
state = $injector.get('$state');
testService = $injector.get('testService');
controller = new ctrl.testController(testService, mdDialog, state);
}));
it("should Create Controller", () => {
controller = new ctrl.testController(testService, mdDialog, state);
spyOn(testService, 'showCLULayer').and.callThrough();
expect(controller).not.toBeNull();
expect(controller.activate).toHaveBeenCalled();
////error Expected a spy, but got Function.
});
});
}
测试到行时抛出错误:
expect(controller.activate).toHaveBeenCalled();
说 期待 spy ,但得到了功能。 Activate 是一个函数,当我调用正在测试的 Controller 的构造函数时会调用该函数。请有人指出我正确的方向。
尝试添加该行
spyOn(controller, 'activate');
在期望之前,我收到以下错误。
Expected spy activate to have been called.
Error: Expected spy activate to have been called.
最佳答案
在测试它是否被调用之前,您需要监视一个函数。尝试这个:
it("should Create Controller", () => {
controller = new ctrl.testController(testService, mdDialog, state);
spyOn(testService, 'showCLULayer').and.callThrough();
expect(controller).not.toBeNull();
spyOn(controller, 'activate'); // < ------------Spy on the function
expect(controller.activate).toHaveBeenCalled();
////error Expected a spy, but got Function.
});
