在测试文件中引入FormsModule，并使用TestBed.configureTestingModule()方法将其添加到测试模块中。示例代码如下：

import { FormsModule } from '@angular/forms';

describe('MyComponent', () => { let component: MyComponent; let fixture: ComponentFixture;

beforeEach(async(() => { TestBed.configureTestingModule({ imports: [ FormsModule ], declarations: [ MyComponent ] }) .compileComponents(); }));

beforeEach(() => { fixture = TestBed.createComponent(MyComponent); component = fixture.componentInstance; fixture.detectChanges(); });

it('should create', () => { expect(component).toBeTruthy(); }); });
