Plain markdown winning over fancy forms is the biggest plot twist Jira didn't see coming. Checkout our file-first approach to test planning - making stories / scenarios accessible for your coding agents. https://t.co/EcMsIFZUJJ #QA #testing #startup #buildinginpublic

𝗕𝗮𝗱 𝗕𝘂𝗴 M𝗼𝗻𝗱𝗮𝘆: 💰 The DAO Hack (2016): A "re-entrancy" bug in a smart contract allowed an attacker to drain $50m in Ethereum. The entire Ethereum blockchain had to be "hard forked". #badbugmonday #crypto #ethereum #hack ⛓️💸

𝗕𝗮𝗱 𝗕𝘂𝗴 𝗠𝗼𝗻𝗱𝗮𝘆: 🎶 Gangnam Style (2014): Psy's hit song "broke" YouTube's view counter, which used a 32-bit integer, maxing out at 2,147,483,647 views. They upgraded to a 64-bit integer. Too popular to count. #badbugmonday #psy 📈💥

Does your app break when José signs up Does Anne-Marie get silently rejected Does a long bio crash the app cos someone forgot VARCHAR(255) These aren’t edge cases. They’re real users Our form-validation agent finds the bugs that chase real people away, before they do #QA

𝗧𝗲𝘀𝘁𝗶𝗻𝗴𝟭𝟬𝟭: ⚙️ What is Functional Testing? A fancy term for checking if the features function. Does the "Save" button save? You'd be surprised how often the answer is no. #testing101 #FunctionalTesting https://t.co/caSEKm7yzo

Stop writing negative test cases for forms. It’s 2026. Our new agent takes your existing "Happy Path" and attempts the invalid inputs for you: ❌ Past dates in future fields ❌ Negative numbers ❌ Random strings https://t.co/0BTWwQxRkW #AutomateTheBoringStuff

𝗕𝗮𝗱 𝗕𝘂𝗴 𝗠𝗼𝗻𝗱𝗮𝘆: 💣 US Patriot Missile (1991): A software bug caused the internal clock to drift by 1/3 of a second over 100 hours. This error made it miss an incoming Scud missile. Timing is everything. #badbugmonday #military 🕒💥

𝗧𝗲𝘀𝘁𝗶𝗻𝗴𝟭𝟬𝟭: ⏱️ What is Performance Testing? Seeing how your app behaves when it's under pressure. Is it fast, or does it take 10 seconds to load a button? Users will judge you. Mercilessly. #testing101 #PerformanceTesting

𝗕𝗮𝗱 𝗕𝘂𝗴 𝗠𝗼𝗻𝗱𝗮𝘆: 👂Apple FaceTime 2019: A bug let you listen to someone's iPhone before they answered the call. You just had to add yourself to the call. The ultimate eavesdropping exploit. #badbugmonday #apple #privacy #facetime 📱🤫 https://t.co/criUyM9oZ8

𝗕𝗮𝗱 𝗕𝘂𝗴 𝗠𝗼𝗻𝗱𝗮𝘆: 🚀 Mariner 1 (1962): NASA's first interplanetary probe was destroyed 5 mins after launch. The cause? A single missing overbar in the guidance code - R instead of R̅. The most expensive typo in history. #badbugmonday #nasa 🛰️✏️

𝗧𝗲𝘀𝘁𝗶𝗻𝗴𝟭𝟬𝟭: 📦 What is System Testing? Testing the entire application, all wired together. This is where you find all the "fun" bugs that only appear when everything is running at once. #testing101 #SystemTesting

Not only do we do regression testing, but we do VISUAL REGRESSION testing. ExploreChimp notices when things change, be it elements moving or even just planned text updates like you can see here. TestChimp will ensure that the only changes on your site are the ones you intend.

𝗕𝗮𝗱 𝗕𝘂𝗴 𝗠𝗼𝗻𝗱𝗮𝘆: 🚀 Ariane 5 Flight 501 (1996): A $370 million rocket self-destructed 40s after launch. The cause? A 64-bit number was converted to 16-bit , causing an overflow. An expensive rounding error. #badbugmonday #aerospace #ariane5 💥💻

Every AI testing tool: “Drop your scripts, trust our agent.” Dev teams: no thanks 🙏 ai-wright: “Keep using Playwright. Just say ai.act() - only when needed.” ✅ Vision-enabled ✅ BYOL ✅ Open source 🌍 https://t.co/BclnYb7qys #playwright #SoftwareTesting #buildinginpublic

𝗧𝗲𝘀𝘁𝗶𝗻𝗴𝟭𝟬𝟭: 🧱 What is a Unit Test? A dev-written test to prove a tiny piece of code (a "unit") does what they think it does. It's the first line of defense against their own mistakes. #testing101 #UnitTesting #TDD

𝗕𝗮𝗱 𝗕𝘂𝗴 𝗠𝗼𝗻𝗱𝗮𝘆: ❤️ Heartbleed (2014): A tiny bug in OpenSSL, a core internet security library, exposed sensitive data (like passwords) across millions of websites. Like finding a key to the internet's back door. #badbugmonday #security 🔓🖥️ https://t.co/e5z21hAw1g

𝗕𝗮𝗱𝗕𝘂𝗴𝗠𝗼𝗻𝗱𝗮𝘆: 📞 AT&T Network Crash (1990): A single line of faulty code in a software update for network switches caused a 9-hour cascade failure, blocking 75 million calls. One break statement broke everything. #badbugmonday #att #outage ☎️🚫

Building AI Agents? Add this to your prompt: "Write a note to your future self". Why? cos unlike humans - Agents see world in snapshots - which means all the "thinking" it did is lost the next time it "wakes up". https://t.co/i0KBM3NZMg #Agents #Startups #buildinginpublic

𝗕𝗮𝗱 𝗕𝘂𝗴 𝗠𝗼𝗻𝗱𝗮𝘆: 🏥 Therac-25 (1985-1987): A radiation therapy machine delivered massive overdoses due to a "race condition" bug. A software flaw that tragically cost lives. #badbugmonday #healthcare 🩺💔 https://t.co/kiosyrQj5t

I'm building a visual regression feature - comparing a base image against a webapp. Mostly it'll be used to help avoid regressions (compare today's site to last week's), but we want to test comparing Figma designs to a final webapp. DM me if you have a design we could test.
