Polly.JS可记录、重放和存根 HTTP 交互的 JavaScript 库
Polly.JS 是 Netflix 开源的一个独立、框架无关的 JavaScript 库,可记录,重放和存根 HTTP 交互。
Polly 利用本地浏览器 API 轻松调试请求和响应,同时让你能够使用简单、功能强大且直观的 API 全面控制每个请求,这将便于后期模拟不同的应用状态(例如加载、报错等)。

Usage
import { Polly } from '@pollyjs/core'; describe('Netflix Homepage', function() { it('should be able to sign in', async function() { /* Create a new polly instance. By default, Polly will connect to both fetch and XHR browser APIs and will record any requests that it hasn't yet seen while replaying ones it has already recorded. */ const polly = new Polly('Sign In'); const { server } = polly; /* Intercept all Google Analytic requests and respond with a 200 */ server .get('/google-analytics/*path') .intercept((req, res) => res.sendStatus(200)); /* Pass-through all GET requests to /coverage */ server.get('/coverage').passthrough(); /* start: pseudo test code */ await visit('/login'); await fillIn('email', 'polly@netflix.com'); await fillIn('password', '@pollyjs'); await submit(); /* end: pseudo test code */ expect(location.pathname).to.equal('/browse'); /* Calling `stop` will persist requests as well as disconnect from any connected browser APIs (e.g. fetch or XHR). */ await polly.stop(); }); });
