当我在运行所有测试时突然发生超时时,我正在向Angular项目中添加应用程序组件测试:
[launcher]: Launching browsers headless with concurrency unlimited
21% building 95/96 modules 1 active .../src/css/public.scss19 [launcher]: Starting browser ChromeHeadless
[HeadlessChrome 75.0.3770 (Mac OS X 10.14.5)]: Connected on socket -d4Du6uXE65XhnZkAAAA with id 51932343
[HeadlessChrome 75.0.3770 (Mac OS X 10.14.5)]: Disconnected (0 times), because no message in 30000 ms.
我最近添加了测试app.component.spec.ts:
...
describe('AppComponent', () => {
beforeEach(async(() => {
TestBed.configureTestingModule({
schemas: [CUSTOM_ELEMENTS_SCHEMA],
imports: [RouterTestingModule],
declarations: [AppComponent],
providers: [...],
}).compileComponents();
}));
it('should create the app', () => {
const fixture = TestBed.createComponent(AppComponent);
const app = fixture.debugElement.componentInstance;
expect(app).toBeTruthy();
});
});
没有任何测试。过了一会儿,我发现CUSTOM_ELEMENTS_SCHEMA导致了超时。现在,我的app.component.html中有一个自定义元素,这就是为什么要添加架构的原因。删除架构(并从html中删除元素)可以解决此问题。
为什么添加架构会导致karma-headlessChrome超时? 另外,将自定义元素添加到应用程序组件是否是错误的做法?
-更新-
结果是我导入了错误的项目:
import { CUSTOM_ELEMENTS_SCHEMA } from '@angular/compiler/src/core';
应该是
import { CUSTOM_ELEMENTS_SCHEMA } from '@angular/core';
答案 0 :(得分:0)
