The "programmers can't name things" trope is real. TDD, or "TEST Driven Development", which has "test" in the name, is about design. But we don't call it "Design Driven Development" because those of us from front-end love our Designers, and just assume that is implied, and they direct us what to build. TDD's value isn't just design, it's testing that our code works, now, after a change, any time we deploy stuff, etc.

... that said, I love when Allen Holub rages, so reposting. That, and us TDD fans are horrible at describing, marketing, and implementing TDD, but we try anyway.
