在为Angular 2应用程序编写测试用例时配置Karma和ng2-bootstrap,可以按照以下步骤进行配置:
npm install -g karma
npm install -g karma-cli
npm install ng2-bootstrap --save-dev
// 初始化测试环境
getTestBed().initTestEnvironment(
BrowserDynamicTestingModule,
platformBrowserDynamicTesting()
);
// 导入所有的测试文件
const context = require.context('./', true, /\.spec\.ts$/);
context.keys().map(context);
```
describe('AppComponent', () => {
beforeEach(async(() => {
TestBed.configureTestingModule({
declarations: [
AppComponent
],
}).compileComponents();
}));
it('should create the app', async(() => {
const fixture = TestBed.createComponent(AppComponent);
const app = fixture.debugElement.componentInstance;
expect(app).toBeTruthy();
}));
it(`should have as title 'app'`, async(() => {
const fixture = TestBed.createComponent(AppComponent);
const app = fixture.debugElement.componentInstance;
expect(app.title).toEqual('app');
}));
it('should render title in a h1 tag', async(() => {
const fixture = TestBed.createComponent(AppComponent);
fixture.detectChanges();
const compiled = fixture.debugElement.nativeElement;
expect(compiled.querySelector('h1').textContent).toContain('Welcome to app!');
}));
});
```
ng test
这样,你就可以在为Angular 2应用程序编写测试用例时配置Karma和ng2-bootstrap了。请注意,这里的配置示例中没有提及腾讯云的相关产品,如果需要了解腾讯云的相关产品和产品介绍,可以参考腾讯云官方文档或咨询腾讯云的技术支持团队。
