使用Angular 2进行Rxjs5测试

npm install @angular/core @angular/common @angular/compiler @angular/platform-browser @angular/platform-browser-dynamic rxjs --save

import 'rxjs/add/operator/map';
import 'rxjs/add/operator/filter';

import { Observable } from 'rxjs/Observable';

describe('RxJS 5 Test', () => {
  it('should perform a simple map operation', () => {
    const source = Observable.of(1, 2, 3);
    const result = source.map(x => x * 2);

    result.subscribe(value => {
      expect(value).toBe(2);
    });
  });

  it('should perform a simple filter operation', () => {
    const source = Observable.of(1, 2, 3);
    const result = source.filter(x => x % 2 === 0);

    result.subscribe(value => {
      expect(value).toBe(2);
    });
  });
});
