Test-Driven Development

Test-Driven Development

Test-Driven Development (TDD) is a proven way of developing software quickly and purposefully. It involves first writing a failing test and then writing only as much productive code as is needed to satisfy that test. If used correctly, this results in clean code that is 100% tested.

With TDD, one does not need to plan the software design ahead, but the design emerges while developing the software. If you realize that the design could be improved, you refactor the code, safe-guarded by the existing tests. This is called the red/green/refactor cycle.

In this training, you will learn about Test-Driven Development and experience directly in Ensemble Programming how to apply it and what to look out for.

Learning Objectives

Target Audience

This training is aimed at participants who program PHP professionally and have always been unhappy about writing too few tests. The training is not necessarily about promoting TDD as the only true way to develop software, but about recognising the advantages of this approach and being able to switch between methodologies as needed.

Requirements

Prerequisites are practical experience with PHPUnit and knowledge of object-oriented programming in PHP. The necessary basics are taught in Advanced PHPUnit and Advanced OOP .
