Question

我使用angular2-cli创建项目，这个spec文件由cli为我的一个组件自动生成。我将我的应用程序升级到rc4，从那时起，当我运行此测试文件时，我遇到了这个问题。以下是规范文件：

import {
inject, ComponentFixture, TestBed
} from '@angular/core/testing';
import { Component } from '@angular/core';
import { By } from '@angular/platform-browser';
import { MockComponent } from './mock.component';

describe('Component: Mock', () => {
let builder: TestBed;

beforeEachProviders(() => [MockComponent]);
beforeEach(inject([TestComponentBuilder], function (tcb:  TestComponentBuilder) {
builder = tcb;
}));

 it('should inject the component', inject([MockComponent],
  (component: MockComponent) => {
expect(component).toBeTruthy();
}));

it('should create the component', inject([], () => {
return builder.createAsync(MockComponentTestController)
  .then((fixture: ComponentFixture<any>) => {
    let query = fixture.debugElement.query(By.directive(MockComponent));
    expect(query).toBeTruthy();
    expect(query.componentInstance).toBeTruthy();
  });
}));
});

@Component({
selector: 'test',
template: `
<test></test>
`,
directives: [MockComponent]
})
class MockComponentTestController {
}

上面的规范文件在＆＃39; createAsync＆＃39;上引发了错误，我非常确定TestBed上不存在createAsync，但是我用TestBed替换了TestComponentBuilder（在rc4中不推荐使用TestComponentBuilder）。请提供有关如何解决此问题的建议。

应为createComponent：

fixture = TestBed.createComponent(AppComponent);
let comp = fixture.componentInstance;

财产＆＃39; createAsync＆＃39;在类型＆＃39; TestBed＆＃39;上不存在
