Clean Code und Software Craftsmanship

Software systems deteriorate while they are being developed, and readability and maintainability can decrease rapidly. In most cases, however, the first indicator of this deterioration is a reduction in development productivity; the knock-on effects of this can include a slow rate of release for new features or unexpected side effects when changes are made. Using the methods of the Clean Code Initiative outlined below can help to prevent loss of quality. In this workshop, you will develop skills using practical examples of test-driven development, learning how to use design patterns effectively, both in pure Java and using state-of-the-art frameworks and tools. You will also learn how to identify problematic sections (code smells), use targeted refactoring to improve software, and utilize review techniques to transfer knowledge and maintain a high level of quality.

A wide range of practical exercises will help you understand key policies and procedures. You will be able to compare and discuss different solutions with the other participants and the trainer. This workshop will give you the opportunity to practice the latest software development skills so you can develop robust code that is not just functional, but easy to understand, maintain, and extend. Use these skills to make your software projects fit for the future.
