Puppeteer是一個node庫，他提供了一組用來操縱Chrome的API（默認headless也就是無UI的chrome，也可以配置為有UI）
Puppeteer(中文翻譯”木偶”) 是 Google Chrome 團隊官方的無界面（無頭或無腦Headless）Chrome 工具，它是一個
Node 庫，提供了一個高級的 API 來控制 DevTools協議上的無頭版 Chrome 。也可以配置為使用完整（非無頭）的 Chrome。Chrome 素來在瀏覽器界穩執牛耳，因此，Chrome Headless 必將成為 web 應用自動化測試的行業標桿。使用 Puppeteer，相當於同時具有 Linux 和 Chrome 雙端的操作能力，應用場景可謂非常之多。此倉庫的建立，即是嘗試各種折騰使用 GoogleChrome Puppeteer；以期在好玩的同時，學到更多有意思的操作。
作用和Selenium相似，但是不能跨平台，只能用在chrome做自動化測試

Q: What is the difference between Puppeteer, Selenium / WebDriver, and PhantomJS?
Selenium / WebDriver is a well-established cross-browser API that is useful for testing cross-browser support.
Puppeteer works only with Chromium or Chrome. However, many teams only run unit tests with a single browser (e.g. PhantomJS). In non-testing use cases, Puppeteer provides a powerful but simple API because it's only targeting one browser that enables you to rapidly develop automation scripts.
Puppeteer bundles the latest versions of Chromium.
Q: Why is the Chrome team building Puppeteer?
The goals of the project are simple:
- Provide a slim, canonical library that highlights the capabilities of the DevTools Protocol.
- Provide a reference implementation for similar testing libraries. Eventually, these other frameworks could adopt Puppeteer as their foundational layer.
- Grow the adoption of headless/automated browser testing.
- Help dogfood new DevTools Protocol features...and catch bugs!
- Learn more about the pain points of automated browser testing and help fill those gaps.
