Webinar: Building Selenium Automation Framework [Voices of Community]

Even though several frameworks are available in the market for automation testing, Selenium is one of the most renowned open-source frameworks used by experts due to its numerous features and benefits.

Fluent Interface Design Pattern in Automation Testing

Recently, I was going through some of the design patterns in Java by reading the book Head First Design Patterns by Eric Freeman, Elisabeth Robson, Bert Bates, and Kathy Sierra.
