Course Preview Video


This is the second module of series called "Pyramid of Refactoring" dedicated to achieving Clean Code.

Source code to review :

The goal of the course is to disentangle the codebase from a set of deeply nested conditional if/else statements. It is a very common case - and if it is left for a long time - then it leads to a very complex legacy code after subsequent code extensions.

We use refactoring techniques and perform all the changes live. The participants download the source code and performs all the changes together with the trainer - step by step. In this sample we make use of Chain of Responsibility Design Pattern as goal of our refactoring journey.

The course ends up with Homework, where the participants can experience the difference between implementing additional requirements within Clean Code and within Legacy Code. This is the difference between skipping and applying Preparatory Refactoring.
