Refactoring is a mainstream programming practice now, but it's been 20 years since the first refactoring tool (Refactoring Browser) was released. This talk briefly outlines the evolution of refactoring in the last few decades and follows up with a discussion on what's happening now in the world of refactoring and what lies ahead. Topics covered: architecture refactoring, new kinds of refactoring tools, refactoring in the context of CI/CD (DevOps), refactoring other than code (e.g., databases), and refactoring for IaC (Infrastructure as Code).

How to develop high quality software? What are the key/fundamental principles for software design? What is the relationship between principles, bad smells, design patterns, and refactoring? Based on 3 years of research on software design principles and design smells, this talk shares key insights on developing high-quality software in industrial contexts.

By attending this session, you’ll get a clear understanding of the key role that design principles play in developing software. Further, you’ll know how to apply design principles in practice. So, don’t miss it!  

Refactoring has received considerable attention in the last decade given the important role it plays in Agile methods. With Martin Fowler popularizing ‘code smells’ in his classic book on Refactoring, most programmers know about smells. However, refactoring design smells and architecture smells is also equally important for creating high quality software. This presentation introduces important design smells and the refactoring strategies for addressing them. The talk includes interesting examples of design smells found in OpenJDK 7.0 (Open source Java Development Kit) code base.
