Automated testing is now an integral part of any modern development process. Developers write tests with the aim to ensure the functionality of an application. These tests are usually created in a programming language (e.g. Java). This inevitably creates a gap between the actual requirements and the test code checking these requirements. ATDD closes this gap by demands largely formulated in natural language, while ensuring their feasibility. The aim of ATDD is to write understandable, easy to maintain and at the same time executable test specifications. The group is headed by Fraunhofer FOKUS researcher Axel Rennoch.
