What is Selenium Grid and how does it work with Docker?

Selenium Grid is a tool that allows you to run tests on different machines and browsers simultaneously. When combined with Docker, it enables you to create isolated environments for your tests, making it easier to manage dependencies and configurations.

Can you explain the architecture of Selenium Grid with Docker?

Sure! The architecture typically consists of a Hub and multiple Nodes. The Hub acts as a central point that receives test requests and distributes them to the Nodes, which are Docker containers running different browser instances.

What are the benefits of using Docker with Selenium Grid?

Using Docker with Selenium Grid provides benefits like easy scalability, consistent environments, and simplified setup. It allows you to quickly spin up or tear down test environments as needed.

How do I set up Selenium Grid with Docker?

You can set it up using Docker Compose. You'll define services for the Hub and Nodes in a docker-compose.yml file, specifying the browser images you want to use.
