Headless Chrome has become the go-to guy when it comes to using automated scripts into the browser. Add the complexity of integrations with a variety of components, and it becomes too hard to run smoothly for the process. But Selenium testing requires installed browsers, regardless of whether Selenium is installed on the cloud or on a local machine, and this is a big one. The testing community with open arms has accepted this wonderful, open-sourced tool. When it comes to automation testing, Selenium leads the industry. Google has been working to ensure that the DevTools community is supported with sufficient support.

Headless browsers are the browsers that run as an app process without any user interface elements. Puppeteer is a Node library that provides a high-level API to control Chrome or chromium driver over the DevTools protocol.īy default, Puppeteer runs in headless mode but with configuration, we can run this in full chrome or chromium-browser(non-headless). It was made for chrome browser by the Chrome DevTools team to help automated or headless browser testing. It also provides the facility to perform automation over cross-browser and now it supports Firefox browser too. There are ample tools like selenium, webdriverIO, protractor, etc available in the market to do automation but what if one wants to extract data from the same web application which is termed as web scraping so here Google Puppeteer comes into the picture to automate web application as well as scraping. In the era of testing, web automation plays an important role.
