In this chapter, you looked at what Selenium Grid is and what its parts are. You configured a Selenium Grid locally and connected to it. You worked in pairs to build a Selenium Grid running on two different machines, where they were able to configure it and run a test on it.

We used different techniques to locate elements on a page and how to interact with them. We created complex locators to find elements. We wrote automation scripts. Finally, we looked at how to troubleshoot common issues, identify real issues, and run automation using a Selenium Grid Now, you've all the necessary skills to test web applications using Selenium.
