Test Driven Development

The course has a good balance of interactive lectures and hands-on exercises. The attendees are expected to pair-up and work on the lab exercises. The instructor will assist the attendees as they work on the exercises. The objective of the course is for the attendees to gain an in depth practical knowledge of the concepts so they can put them to immediate use on real projects.
