Notes:
This report documents the results of a case study into four projects that used TDD during development. Three projects at Microsoft and one at IBM were included in the case study. The report concludes that TDD does improve the quality of the delivered software and a reduction in the defect density when the software is released. It also showed that the development time increased; however this was offset by reduced integration testing.
