For many years we created software applications which started off great. We had a great vision and sometimes even a plan. Well, after finishing them most of the time we didn’t like the outcome because it was hard to understand and usual badly tested.

Most of the developers out there heard of clean code, SOLID and DDD. Well, it’s not about spaces vs. tabs but about how to structure your code in the sense of logic. The separation between architecture and implementation.

Let’s talk about how source code should look like and how this will help you to get it better readable, easier understandable, perfectly testable.

## What you will learn from this talk
- A better understanding of SOLID and DDD.
- How good code could look like and that it is readable like a book.
- That 100% code coverage helps extremely.
- How to separate between own code and external libraries.

## Why should you accept this talk
This is a completely new talk I'd love to prepare for your conference. I want to show based on examples how clean coding should look like. I want to go into detail on SOLID, Domain Driven Design (DDD), How 100% code coverage will help, Why you should do Test Driven Development (TDD) at least while fixing bugs and why in 99.9% of the cases inline comments aren’t needed at all. I’ll try to prepare the code shown in the presentation as a repository on GitHub. So everyone can have a detailed look afterward on the examples again.
