How does a design system win over product developers and designers? Everyone wants to ship new features, but they don't know why they should adopt your components and follow your guidelines. Let’s solve this, and turn apathy into excitement. We’ll explore the many ways to attract attention to your design system, elevate its place in your product, and build a thriving community around your work.

Are tests a chore, or do they help us move faster? Let’s examine what makes testing great and not so great. We’ll focus on test strategies that help us code with confidence and clarity, and where they can cost us time and energy. The secret to good testing lies in how it shapes our developer experience. Do our tests give us useful feedback in a timely manner? How quickly can we tell what is wrong when a test suite fails? Do they document our features and explain our past decisions? We’ll answer these questions with better tests that give us joy.
