Puppeteer簡介

puppeteer經常使用API

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，也能夠配置爲有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 。也能夠配置爲使用完整（非無頭）的 Chrome。Chrome 素來在瀏覽器界穩執牛耳，所以，Chrome Headless 必將成爲 web 應用自動化測試的行業標杆。使用 Puppeteer，至關於同時具備 Linux 和 Chrome 雙端的操做能力，應用場景可謂很是之多。此倉庫的創建，便是嘗試各類折騰使用 GoogleChrome Puppeteer；以期在好玩的同時，學到更多有意思的操做。

做用和Selenium類似，可是不能跨平臺，只能用在chrome作自動化測試

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.
