The hardest part of scaling Playwright across an enterprise isn’t writing initial tests—it’s preventing your automation from becoming a copy-pasted, high-maintenance maze.

In this webinar, Jan Molak, creator of Serenity/JS and co-author of BDD in Action, Second Edition, explores how to move beyond isolated scripts to build a shared test architecture. Rather than treating test suites as team silos, he focuses on design patterns that allow multiple projects to share execution logic while delivering actionable release signals to engineering leads, architects, and product owners alike.

The session looks inside the Serenity/JS HTML Reporter’s own test suite, showing how composable patterns test a complex SPA across 3 viewports, 7 views, and hundreds of scenarios. You will explore a walkthrough of the new reporter, a single npm package requiring no Java, showing how build trends, error clustering, and flaky test detection answer “can we ship?” in 30 seconds. Finally, we’ll discuss upcoming Visual AI integration integrations that combine functional evidence with visual regression detection in a single report.

Key takeaways:

• How the Screenplay Pattern provides an architecture for composable, shared test libraries
• Why test reports should serve as a quality tool for the whole team, not just developers
• How progressive adoption delivers immediate reporting value without rewriting existing Playwright code
• What trend history and error clustering reveal that single-run test reports miss entirely
• How structured design patterns bridge technical debugging and business release decisions
