Jan Van RyswyckFor me, one of the best definitions of Test-Driven Development comes from the paper "Mock Roles, Not Objects" by Steve Freeman, Nat Pryce, Tim Mackinnon, Joe Walnes. <a href="http://jmock.org/oopsla2004.pdf" rel="nofollow noopener" translate="no" target="_blank">http://jmock.org/oopsla2004.pdf</a><a href="https://mastodon.social/tags/tdd" class="mention hashtag" rel="nofollow noopener" target="_blank">#tdd</a> <a href="https://mastodon.social/tags/unittests" class="mention hashtag" rel="nofollow noopener" target="_blank">#unittests</a> <a href="https://mastodon.social/tags/softwaredesign" class="mention hashtag" rel="nofollow noopener" target="_blank">#softwaredesign</a>

dtanzerIn software development, we have many ways to speed up the time until we get good feedback (in this video, I talk about test-driven development or <a href="https://social.devteams.at/tags/TDD" class="mention hashtag" rel="nofollow noopener" target="_blank">#TDD</a>).So, if we are in an environment where we get feedback slowly, we are choosing slow feedback - deliberately or by neglect.Why are so many choosing slow feedback? <a href="https://videos.devteams.at/w/x5Hkwz6ey1GeNF5sZRKAcP" rel="nofollow noopener" translate="no" target="_blank">https://videos.devteams.at/w/x5Hkwz6ey1GeNF5sZRKAcP</a>If you prefer youtube, watch here: <a href="https://youtu.be/NIP13D9cEgc" rel="nofollow noopener" translate="no" target="_blank">https://youtu.be/NIP13D9cEgc</a>

glynRecently: 1. While writing a blog post, realised there was a bug in the code I was describing. 2. Wrote a test to demonstrate the bug. 3. The test passed. 4. Tried to debug why the test passed. 5. Couldn't see any reason the test should pass. 6. Realised the test had a bug. Doh! 7. Fixed the test, which then failed. Relief. 8. Fixed the anticipated bug. 9. Test passed, this time for the right reason.<a href="https://fosstodon.org/tags/TDD" class="mention hashtag" rel="nofollow noopener" target="_blank">#TDD</a>

Miguel Afonso Caetano"So you can think really big thoughts and the leverage of having those big thoughts is just suddenly expanded enormously. I had this tweet, whatever, two years ago where I said 90% of my skills just went to zero dollars and 10% of my skills just went up a thousand X.And this is exactly what I'm talking about. So Having a vision, being able to set milestones towards that vision, keeping track of a design to maintain the levels or control the levels of complexity as you go forward. Those are hugely leveraged skills now. compared to I know where to put the ampersands and the stars and the brackets in Rust. You know, I'm programming in every language under the sun. And I just kind of don't care. I'm learning by osmosis. I'm learning about the languages. But, you know, and I was a language guy. I loved languages and the details of languages."<a href="https://newsletter.pragmaticengineer.com/p/tdd-ai-agents-and-coding-with-kent" rel="nofollow noopener" translate="no" target="_blank">https://newsletter.pragmaticengineer.com/p/tdd-ai-agents-and-coding-with-kent</a><a href="https://tldr.nettime.org/tags/Programming" class="mention hashtag" rel="nofollow noopener" target="_blank">#Programming</a> <a href="https://tldr.nettime.org/tags/AI" class="mention hashtag" rel="nofollow noopener" target="_blank">#AI</a> <a href="https://tldr.nettime.org/tags/GenerativeAI" class="mention hashtag" rel="nofollow noopener" target="_blank">#GenerativeAI</a> <a href="https://tldr.nettime.org/tags/VibeCoding" class="mention hashtag" rel="nofollow noopener" target="_blank">#VibeCoding</a> <a href="https://tldr.nettime.org/tags/XP" class="mention hashtag" rel="nofollow noopener" target="_blank">#XP</a> <a href="https://tldr.nettime.org/tags/TDD" class="mention hashtag" rel="nofollow noopener" target="_blank">#TDD</a> <a href="https://tldr.nettime.org/tags/SoftwareDevelopment" class="mention hashtag" rel="nofollow noopener" target="_blank">#SoftwareDevelopment</a> <a href="https://tldr.nettime.org/tags/SoftwareEngineering" class="mention hashtag" rel="nofollow noopener" target="_blank">#SoftwareEngineering</a> <a href="https://tldr.nettime.org/tags/TestDrivenDevelopment" class="mention hashtag" rel="nofollow noopener" target="_blank">#TestDrivenDevelopment</a>
