Guide Refactorings With Behavioral Code Analysis
Many codebases contain code that is overly complicated, hard to understand, and hence expensive to change. The pressure of new features and user needs makes it hard to stop and backtrack, and the longer we wait, the worse it's going to be. Mix in the people side with frequent organizational change and the siren song of a system rewrite becomes more and more attractive.
It doesn't have to be that way, and in this presentation you'll see how easily obtained version-control data let us uncover the behavior and patterns of the development organization to prioritize and guide refactorings. We cover refactoring techniques that reduce excess complexity, address hidden implicit dependencies, and discuss architectural restructuring that reduce inter-team coordination needs. Since behavioral code analysis also lets us consider the social side of code, such as refactoring modules that are under development by our peers, we explore novel patterns that help us limit risks and code conflicts. The specific examples are from real-world codebases like Android, the Linux Kernel, ASP.NET Core MVC, and more.
