Beyond Page Objects: Next Generation Test Automation with Serenity and the Screenplay Pattern

Automated acceptance testing reduces time wasted in manual testing and bug fixing, and when combined with Behaviour-Driven Development, can guide development effort. But it requires skill, practice and discipline. The Screenplay Pattern helps teams address these difficulties and is where you may end up by mercilessly refactoring Page Objects using SOLID design principles.
