I'm currently working on mastering HTMLUnit to test the functionality of JavaScript elements on various websites. Despite my efforts to study and follow the HTMLUnit How-To guides, I have not been successful. The main issue arises when I attempt to execute my program - I am prompted to select a method of execution which I am unfamiliar with. Can someone please offer guidance in this matter?
Upon running the program, all I encounter is a console window awaiting input. This outcome is definitely not what I had anticipated or desired.
