Hướng dẫn selenium cheat sheet java

As you know, I am a big fan of Selenium WebDriver. You can find tonnes of useful Java code in my Web Automation Java Series. I lead automated testing courses and train people how to write tests all the time. The thing that was missing in the materials was a sheet containing all of the most relevant Java code snippets. So I decided to fill that gap. So, I created the most complete Selenium WebDriver Java cheat sheet. I hope that you will find it useful. Enjoy!

Initially, I created the C# cheat sheet while we developed the first versions of the BELLATRIX automated testing framework. Here is a Java version of it, revisited in 2021.
