Page Objects, Builders, and Facades: Key Test Automation Design Patterns Explained Free e-book: The 7 success factors of software testing. 25 years of project experience in one 33-page workbook, now also in English Get it for free "Design patterns support extensibility of our test automation solutions." - Kostiantyn Teltov In this episode, I talk with Kostiantyn Teltov about design patterns in test automation. Kosta shows why test code needs the same care as product code. Page Object to cut duplication. Builder to shape data like choosing a burger. Facade as a reception that guides you to the right service. We touch creational patterns and even pools for drivers. DRY, KISS, and YAGNI keep us honest and stop overdesign. Kostiantyn Teltov was born in Dnipro, Ukraine, and lives in Kraków, Poland, for the past three years. He has been working in software testing since 2008 and writing code for over 11 years. His technical background includes C#, Java, JavaScript/TypeScript, and Python, and he can speak four languages - though not all my programming and speaking languages are equally good ;-) He is a strong advocate of the Shift-Left testing mindset and the Testing Pyramid approach.
