这是我的控制器:
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();
}
}
以下是我的单元测试:
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.
});
});
}
测试在到达行时抛出错误:
expect(controller.activate).toHaveBeenCalled();
说预期是间谍,但得到了功能。 Activate是一个函数,当我调用我正在测试的控制器的构造函数时调用它。有人可以指出我正确的方向。
尝试添加行
spyOn(controller, 'activate');
在预期之前,我收到以下错误。
Expected spy activate to have been called.
Error: Expected spy activate to have been called.
答案 0 :(得分:14)
在测试函数是否被调用之前,您需要监视函数。试试这个:
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.
});
