Abstract

The goal of this work is to study the effects of the adoption of agile practices on open source development. In particular, we started to evaluate the effects of TDD (Test Driven Development) since it is easer to apply in a distributed environment than most other agile practices. In order to reach this goal we used the simulation modeling approach. We developed a simulation model of open source software development process. The model was tuned using data from a real FLOSS project: Apache HTTP Server. To introduce the TDD practice in our FLOSS simulation model, we made some assumptions based on empirical results. The two FLOSS development models (nonTDD and TDD) were compared. The one incorporating the agile practice yields better results in terms of code quality.
