Welcome to the 248th edition of Coding Jag brought to you by TestMu AI!👐
⚡ AI writes 30% of Google’s code, but dev speed? Hardly moving. What’s slowing them down? Tariq Shaukat digs into the real productivity paradox (spoiler: it’s not just about code).
But there’s a lot more packed in this edition. Get an inside look at how GitHub engineers fix platform issues without breaking things. And wait till you see how ZOD + AJV are shaking up API validation in Cypress. Exciting, right? Also, if you are using Playwright and want to scale E2E tests, you’ll want to steal the smarter patterns that run 500+ tests without melting your CI.
Wait!!!!... We’ve got more: Witness how Best Egg scaled to 2.7 M tests and cut test time by 75% using TestMu AI AI-native platform. 💥
