Extending the SEMAT Kernel with the TDD practice

Abstract

Coping with ever increasing complexity is one of the main challenges of software engineering. Applying proven practices through established software processes is a viable way to introduce consistency and tame complexity. The SEMAT is a novel meta-process aiming to encompass commonalities across a disparate set of different software processes. The goal is to create a framework, giving proper jumpstart to any proprietary customisation. This is crucial, as various types of software demand diverse software processes (there is no one-size-fits-all method). On the other hand, all processes strive for a disciplined application of valid development and maintenance routines. This paper analyses a set of methodologies for several software development lines to recognise common and specific development practices. A special emphasise is put on the test-driven development (TDD), showcasing its significant contribution in improving the total quality of the end product. The SEMAT Kernel is extended with additional set of alphas, which are elaborated in detail including containing states, transitions and dependencies. The TDD practice activities were analysed for each introduced alpha as state transition triggers. Consequently, the high-level development plan is expanded with newly defined alphas, providing a powerful tool for performing all sorts of system analysis.
