This article discusses 28 Selenium WebDriver commands in NUnit, a test automation framework for C#. The commands are divided into three categories based on the type of browser interactions: web browser commands, web element commands, and drop-down commands. Web browser commands include actions such as opening, closing, or maximizing the browser window, while web element commands handle different WebElements in the current window. Drop-down commands perform actions on drop-down elements in the current window. The article provides examples for each command and explains how to use them effectively in automated testing scenarios.
