What are the main advantages of using Selenium Grid?

Selenium Grid allows running tests in parallel on different machines and browsers, significantly speeding up the testing process. Main advantages:

• Parallel test execution: reduces overall testing time.
• Cross-browser testing: can simultaneously verify application functionality across different browsers and their versions.
• Scalability: easily add new nodes to expand the testing infrastructure.
• Centralized management: the hub manages the distribution of tests across nodes.

Example of use: you can set up a hub on one server and connect multiple nodes with different OS and browsers to run tests simultaneously on Windows with Chrome and Linux with Firefox.
