Włodek Krakowski Workshop in Barcelona: Effective Refactoring

Next October 23rd Apium Academy will organize a new workshop in our installations in Barcelona. After Len Bass’ DevOps and Mark Richards’ Software Architecture workshops, now it’s time for Włodek Krakowski and his Effective Refactoring workshop. Włodek Krakowski is an independent technical trainer specializing in maintaining code quality through refactoring. His main interest is taking care of delivering valued software from different perspectives. He writes blog at www.refactoring.pl.

During the workshop we go carefully through the concept of Pyramid of Refactoring:

The training is mainly focused on working with code using automated refactoring-features that are built into IntelliJ or Eclipse. The source code is based on Java language. The trainer does all the refactorings live in small steps what allows the attendees to follow it with the same changes on their laptops. Remaining 25% of the training is dedicated to motivation part, how to make refactoring a daily habit in order to keep technical debt under control.

Timetable:

  • Class Start: 09:00
  • Coffee Break: 10:45-11:00
  • Lunch Break: 12:45-13:30
  • Coffee Break: 15:00-15:30
  • Coffee Break: 16:30-16:45
  • Class End: 17:30

Goals of the Workshop:

  • Learn to tackle with technical debt on daily basis. Feel the thrill of refactoring and make it a habit to maintain code readability and extendibility continuously.
  • Retain code quality by refactoring in the smallest possible steps so it becomes everyday practice. This allow to continue with much more complex refactorings when needed.

Effective Refactoring: Topics:

  • Part 1
    • Start with a small code that is easy to catch up with
    • Understand how easy to extend it using copy-paste approach but make it harder to maintain at the same time
    • Divide the design into smaller pieces using Pyramid of Refactoring approach
    • Learn lots of build-in IDE refactoring
    • Talk about SOLID design that is the basement of Pyramid of Refactoring
  • Part 2
    • Start with that same code from part 1 where new requirements were implemented using copy-paste approach without any refactorings
    • Describe additional requirements that needs to be implemented
    • Understand how much more difficult it is now to continue using copy-paste approach and continue to make the code less and less maintainable at the same time
    • Extract the “extension” points using the Pyramid of Refactoring
    • Implement the new functionality as and pluggable parts using small amount of TDD

Requirements and Reference Materials:

We will use Java 1.8 version as compiler.

All the attendees are expected to install the below before the workshop, so all attendees start the workshop together at the same time.

  • Java 1.8 (or newer)
  • IntelliJ Community Edition (or Ultimate Edition if you own the licence)
  • Maven 3

The Java Source Code to be installed will be provided during the workshop.
