The official documentation for Playwright reads:
The resemblance to Google's Puppeteer is striking, and for good reason.
# Puppeteer vs Playwright
In the words of the authors:
We are the same team that originally built Puppeteer at Google [...]. With Playwright, we'd like to take it one step further and offer the same functionality for all the popular rendering engines. We'd like to see Playwright vendor-neutral and shared governed.
In short, Playwright builds on the experience of Puppeteer to provide a way to:
- run against all major browsers (Chromium/Chrome, Firefox, WebKit/Safari)
- write more concise scripts (e.g. minimising the need for explicit waits)
- easily migrate existing codebases (keeping a very similar API)
This is achieved in the form of a compact node library that exposes a high-level API to interact with web pages in a fast, secure, stable and simple way. As it is an open-source project, you can contribute to it yourself.
# Main use cases
- Test automation in modern web applications: verifying that the features we are exposing our users/customers to are actually behaving as expected.
- Cross-browser testing: ensuring applications are working consistently across browsers and rendering engines.
- Taking screenshots of web pages: useful for a variety of different uses going from simple archiving to automated comparison for e.g. visual testing.
- Scraping web sites for data: extracting data from websites for later retrieval or analysis.
- Automating interaction of web pages: speed up and scale any sort of sequence of actions we would like to perform on a website automatically.
In this guide you will find multiple examples showing how to leverage Playwright, with a focus on test automation / active reliability.
