在全新安装ng new myapp
(cli 版本 1.6.8、Angular 5.2.0、rxjs 5.5.6)时,我安装了 rxjs 弹珠。
由于某些配置原因,我在运行非常基本的测试时遇到问题。谁能告诉我出了什么问题?
import { TestBed, async } from '@angular/core/testing';
import { marbles } from 'rxjs-marbles/jasmine';
import { map } from 'rxjs/operators';
import { AppComponent } from './app.component';
describe('AppComponent', () => {
beforeEach(async(() => {
TestBed.configureTestingModule({
declarations: [
AppComponent,
],
}).compileComponents();
}));
it('should see mapped values', marbles(m => {
const values = { a: 1, b: 2, c: 3, x: 2, y: 4, z: 6 };
const source = m.cold('--a---b---c-|', values);
const expected = m.cold('--x---y---z-|', values);
const result = source.pipe(map(x => x * 2));
m.expect(result).toBeObservable(expected);
}));
});
控制台错误:
