Description: Google TechTalks March 17, 2006 Dave Astels Dave Astels (co-author of "A Practical Guide to eXtreme Programming" and author of Jolt Award winning "Test-driven Development: A Practical Guide") has over 2 decades of experience in the software field, most of that involved with object-oriented technologies and techniques. Dave has been studying, practicing, teaching, evangelising, and coaching XP and Agile Processes since 1998. Dave's experience ranges from embedded process control systems to consumer products (both consumer electronics and shrinkwrapped software) to energy trading systems. Dave is an independant software consultant specializing in the areas of agile process, programming practices, and object design/architecture. Dave is one of the thought leaders in the area of TDD, and now BDD. ABSTRACT Test Driven Development (TDD) has become quite well known. Many developers are getting benefit from the practice. But it is possible that we can get even more value. A new practice is getting attention these days: Behaviour Driven Development (BDD). BDD removes all vestiges of testing and instead focuses on specifying the behaviour desired in the system being built. This talk will be focus on Ruby and will introduce a new BDD framework: rSpec. The ideas, however, are language independent.
