angular - 错误 : Cannot create the component ComponentClass as it was not imported into the testing module

Question

我在 Angular Cli 6.0.1 应用程序上设置了上述测试基础。

使用 Jasmine V2.8.0 和 Karma V2.0.0

我在第 13 行收到以下错误

错误:无法创建组件 AddressLookUpDirective，因为它没有导入到测试模块中!

无法弄清楚出了什么问题..欢迎提出任何建议

import { TestBed, ComponentFixture } from '@angular/core/testing';
import { BrowserDynamicTestingModule, platformBrowserDynamicTesting } from '@angular/platform-browser-dynamic/testing';

import { AddressLookUpDirective } from './address-look-up.directive';

describe('AddressLookUpDirective', () => {

    let component: AddressLookUpDirective;
    let fixture: ComponentFixture<AddressLookUpDirective>;

    beforeEach(() => {

        TestBed.configureTestingModule({
        declarations: [
            AddressLookUpDirective
          ]
        });

       fixture = TestBed.createComponent(AddressLookUpDirective);
       component = fixture.componentInstance;

   });
});

您应该创建一个模拟组件来测试指令并将指令和模拟组件导入 TestBed。

@Component({
    template: `<input type="text" hoverfocus>` 
})
class TestHoverFocusComponent {
}
