Nocketeer NPM | npm.io

About

Nocketeer is a Puppeteer helper library to run chrome headless browser in isolation. It is inspired by Nock.back library.

How it works

Nocketeer works by overriding Puppeteer's Request event and providing mock responses.

Nocketeer works in Record and Play mode. In record mode it intercepts http calls and saves them as json fixtures. In play mode it just replay those saved responses.

Installation

$ npm install nocketeer

Usage

const nocketeer = require('nocketeer');
const puppeteer = require('puppeteer');

(async () => {
  const browser = await puppeteer.launch();
  const page = await browser.newPage();
  await nocketeer(browser);
  await page.goto('https://www.example.com');
  await page.close();
  await browser.close();
})();

Save above script as index.js

Record mode

> node index.js

Play mode

> CI=true node index.js
