Test-driven Development: An On-stage Demonstration

Test-driven development (TDD) is a skill that takes patience to master-you can’t learn it reading a book. As with learning any new language, to gain fluency you need to practice TDD with competent coaching and lots of hard work. Many well-intentioned programmers try and finally give up on TDD because they never develop the fluency it requires. On stage, Llewellyn Falco leads a live TDD demonstration, talking through the process and microsteps of: (1) studying a feature, (2) creating an initial test, and (3) iteratively developing the related test code and feature code until the feature is completely programmed. Watch how to iteratively write a test, see it fail, and then write the feature code to make it pass. After explaining the theory behind the particular TDD technique used, Llewellyn leads participants in testing progressively more complex objects and scenarios.
