James Grenning on Test-Driven Development - Episode 114

James Grenning joins the podcast this episode to discuss test-driven development.   James is one of the original authors of the Agile Manifesto. His specialties include test-driven development and embedded software going deep in C-based embedded technologies. At his company Wingman Software, he coaches and trains developers to deliver more. With deadlines to meet, quality goals to meet, and customers to satisfy, a developer’s day can often be packed to the brim with little time for investigating better ways to develop — this is where Wingman Software comes in. They offer training, coaching, consulting, and workshops for developers and teams looking to accelerate their progress and reach a new level of performance.   In this episode, James speaks about where test-driven development is today, how it has changed over the decades and his key advice for transitioning to TDD. He also shares some fun tips, from ZOMBIES guiding you through the process of TDD to the secrets of how to become a highly productive team or developer!   Topics of Discussion: [:38] Be sure to visit AzureDevOps.Show for past episodes and show notes.
