Explore the critical relationship between unit testing and code design in this insightful keynote presentation by Victor Rentea at Devoxx. Delve into the concept that difficult-to-write tests often indicate suboptimal production code design. Discover how unit testing provides comprehensive feedback on code structure and learn to interpret these signals for improved software architecture. Examine common pitfalls, including the tendency to abandon testing or resort to superficial tests when faced with challenges. Analyze the opposite extreme of overly complex, mock-heavy tests that can hinder rather than help development. Gain valuable insights into a range of design principles, from fundamental improvements to nuanced concepts, all derived from the messages your unit tests are conveying about your code.
