Total TDD | VOL. 1 What Is It, What To Do When It Goes Wrong & Why Hasn’t It Taken Over The World?
AI Summary
In this episode, Dave Farley discusses the importance of test-driven development (TDD) in software engineering. He emphasizes that TDD is not just about testing but rather a methodology that promotes better design and code quality through iterative development and verification of code against tests. Through examples and insights, he explains how TDD can significantly reduce production defects, citing a case where a company saw a 90% drop in issues after adopting continuous delivery alongside TDD practices. Farley outlines the principles of TDD, including the ‘red-green-refactor’ mantra, and identifies common anti-patterns in TDD practices that can lead to poor design and test inefficiencies. He concludes by urging developers to embrace TDD as a means to enhance their coding skills and produce higher quality software.
