The tutorial on Selenium Java focuses on using the Class Name Locator to identify web elements during automation testing. It demonstrates practical examples, such as locating the 'Where' field on Airbnb and handling exceptions with Facebook's compound class names using alternative methods like CSS selectors or XPath. When elements share the same class name, the tutorial suggests using the "findElements" method and iterating through indices to target specific elements, as highlighted in the LinkedIn sign-up page example. The guide addresses common errors and offers solutions for effective use of Class Name Locator in Selenium, emphasizing the importance of alternative strategies when dealing with complex scenarios. The tutorial is authored by Sadhvi Singh, a QA Manager with extensive experience in various testing domains and accolades in ISTQB certification.
