Clean Code Cheat Sheet (V 2.4)
C
I updated my clean code cheat sheet. This time there are just minor changes: Principles: mind-sized components Class Design: do stuff or know others, but not both Maintainability killers: tangles Refactoring patterns: refactor before adding functionality, small refactorings removed duplication regarding one test asserts one thing TDD principles: Test domain specific languages fixed a bug in the ATDD/TDD cycle (run all acceptance tests) If you miss something or think that there is something just...
Legacy Code and Now What?

cross-post from Every day is a ground hog day. It is eight o’clock in the morning. You come into the office, look at the Scrum board of your current project and pick the next task of the user story with the highest priority. You sit fully motivated in front of your computer, open up your favorite IDE and start to implement the task. But wait! Something is wrong!

To get the most out of these acceptance tests, I want to fake as little as...
Presentation: Agile Code Design – how to keep your code flexible
P
These are the slides along with some comments from a presentation I gave lately in the bbv .Net System boot camp – the yearly education week of my division in my company. Once upon a time, Agile Software development came to our software development country. Like a monster, Agile software methodologies scared the hell out of us. Suddenly, we had to find ways how to build software so that we could keep up with the high rate of change, just-in-time requirements and a sacrificial offering – a...
