## What it is
Symfony Panther is a PHP library for browser testing and web scraping that drives real browsers (Chrome, Firefox) via the W3C WebDriver protocol. It integrates with PHPUnit and Symfony's testing tools to run end-to-end tests and crawl JavaScript-heavy websites.

## Use cases
- run end-to-end tests in a real browser for a Symfony app
- scrape websites that require JavaScript rendering
- take screenshots during automated browser tests
- test real-time apps using WebSockets or Server-Sent Events
- execute JavaScript on pages during tests
- integrate browser tests into CI pipelines like GitHub Actions

## When to choose
- you need E2E browser testing in a PHP or Symfony project
- you want to scrape JavaScript-rendered pages from PHP
- you want WebDriver/Selenium-based testing with PHPUnit integration

## When to avoid
- you need browser testing in a non-PHP stack
- you only need simple HTTP-level tests without a real browser
- you need high-performance large-scale crawling rather than testing

## Facets
- artifact type: library
- maturity: active
- function: e2e-testing, web-scraping, testing, http-client
- domain: testing, web-development, crawlers, developer-tools
- platform: php, cross-platform, cli
- tags: webdriver, selenium, chromedriver, symfony, browser-automation, phpunit
