How can I use Selenium Grid with Docker for advanced testing?

You can set up Selenium Grid with Docker by using Docker Compose to define your services. Would you like a sample configuration?

Yes, please provide a sample Docker Compose file.

Here's a basic example:

version: '3'
services:
  selenium-hub:
    image: selenium/hub
    ports:
      - "4444:4444"
  chrome:
    image: selenium/node-chrome
    depends_on:
      - selenium-hub
    environment:
      - HUB_HOST=selenium-hub
  firefox:
    image: selenium/node-firefox
    depends_on:
      - selenium-hub
    environment:
      - HUB_HOST=selenium-hub

How do I run tests on this setup?

You can run your tests by connecting to the Selenium Hub at http://localhost:4444/wd/hub. Make sure your test scripts point to this URL.
