Live Refactoring

Refactoring means improving the structure of software without changing its externally observable behaviour. Each individual refactoring step, such as introducing a new method or renaming a variable, is small and therefore low-risk to implement.

In this compact training, you will experience in live coding style how to improve existing programme code step by step through refactoring, for example to prepare the implementation of a new feature, to make code easier to understand or to remove duplicated code.

Learning Objectives

You understand refactoring as a strictly methodical approach to improve the structure of code
You can assess when refactoring is worthwhile from an economic point of view
You can safely refactor previously untested code with characterisation tests

Target Audience

Developers with PHP programming skills who need to maintain and further develop existing programmes. Experience with PHPUnit is an advantage, but not a prerequisite for this training.

Requirements

Attendees should have at least 1-2 years of experience programming with PHP or a similar programming language. They should have experience with procedural and object-oriented programming and be confident in using an IDE and common development tools such as the version control Git.
