Years with an HN recommendation, 2007–2026
HN points to it as a fun, substantive exchange between two experienced practitioners on TDD's value.
Jim Coplien and Bob Martin debate test-driven development and unit testing in an InfoQ video that grew out of a JAOO 2007 dispute. They also touch on design and architecture.
“this was a fun discussion about TDD between two professionals” (HN, 2016)
Yeah, I agree. TDD is also, you cannot write a single line of code without writing a failing unit test though. Well, I'm not a fan of that either. I mean, sometimes I like writing an acceptance test to begin with and work inwards. People sometimes interchangeably use "TDD" for "testing". Also, just because you do TDD, doesn't mean your code can be great, I've seen people assert pointless things and the unit has gotten so small that people now define them as methods in classes. Which I also think can lead to some crazy maintenance suite of tests. If you're interested, this was a fun discussion about TDD between two professionals: [this video] Jim Coplien and Uncle Bob.
I feel James Coplien's advice on the question is interesting: [this video] TLDW: "refactoring your way out" from a simple but too short-sighted design might take a ridiculous amount of work, compared what would have been necessary if you knew what a "correct" design for this problem was.
Coplien's advice on short-sighted design versus refactoring effort.
