27: Fabulous new mistakes
Giant Robots Smashing Into Other Giant Robots - Un pódcast de thoughtbot - Jueves
Categorías:
Ben Orenstein is joined by Joe Ferris, CTO of thoughtbot. Inspired by a question on Law of Demeter from listener Nathan Long, Joe and Ben (hopefully) answer Nathan's question, and then go on to discuss how the Law of Demeter is a form of duplication, how it effects testing, and how to better architect your report, your view, or your entire system to better obey the Law of Demeter. They also touch upon Rails' try method, how the pain of testing helps guide the code you write, where the Law of Demeter doesn't apply, how people don't refactor their tests, how to productively refactor your tests and avoid wasting time rewriting things, and much more.
