Test Driven Development in Extreme Programming

By Pavan Kumar Gorakavi

1. What is Extreme Programming?

Extreme programming is a software engineering methodology which has gained its importance in the arena of agile software development methodologies. Extreme Programming was initially formulated by Kent Beck.

Extreme Programming is a disciplined methodology which stresses customer satisfaction. It basically underlines the concept of ‘deliver when needed’. Unlike conventional practices, agile practices maintain minimal re-factoring costs. Agile process primarily focuses on high interaction, working model, customer collaboration, regular feedbacks, and flexibility for changing requirements.

Extreme programming encourages a high degree of interactions between team players, which include developers, testers, managers, business owners and others. This practice advises the team to possess a lucid information system. Extreme programming emphasizes not just testing, but testing well. Test cases and tests are created at all stages of coding. As Extreme programming provides early feedback, it will reduce failure cost.  It provides a flexible environment for both customers and developers for changing requirements.

Extreme programming needs effective teams with size of 5-20 team players. Small teams handling smaller module yield an efficient output in XP practice. XP address the problem of huge development cost by providing early prototype features.
