From BasePage to Mixins: The Evolution of Playwright Page Objects
Why BasePage inheritance hits a ceiling and how mixin-based composition makes Playwright frameworks modular, scalable, and production-ready.
Steven Granados
Results-driven QA Engineer transforming quality processes with measurable business impact. I build scalable automation solutions that prevent bugs, reduce costs by 50%, and achieve 80%+ regression coverage across web and mobile platforms.
I'm a Quality Engineer with 7 years of experience building automation solutions that prevent bugs, reduce costs, and accelerate delivery. When I'm not crafting test frameworks, you'll find me gaming, watching anime, or spending time with my family.
I believe quality engineering is about empowering teams, not just finding defects. I've reduced test costs by 80%, mentored QA engineers into senior roles, and built automation frameworks that achieve 99% stability across mobile and web platforms.
Strategic automation backed by solid documentation. I've led cross-platform projects (iOS, Android, Web) using Playwright, Espresso, XCUITest, and WebDriverIO—always prioritizing maintainability and business impact over flashy metrics.
