P.01AI tools write code fast. TDD asks you to slow down and write tests first. These two impulses seem to be in tension. Here's how they actually work together.
P.02Most E2E test suites start fast and grow painful. Playwright solves most of that, but only if you set it up right from the start. Here is what actually works in production.
P.03k6 is a developer-friendly load testing tool with JavaScript scripting, CI integration, and clear metrics. Here's how to write meaningful load tests, interpret the results, and catch performance regressions before they reach production.
P.04Vitest runs faster, works natively with ESM and TypeScript, and uses the same API as Jest. If you're still on Jest in a Vite-based project, here's the case for switching and exactly how to do it.
P.05Most E2E test suites break as fast as the features they cover. Here's how to write Playwright tests that hold up when the UI changes, the data changes, and the team keeps shipping.
P.06Unit tests tell you if your code does what you wrote. They don't tell you if your AI feature does what users need. Here's how to build an evaluation pipeline that catches the failures that matter before users do.
P.07We automated visual regression testing, test generation, and bug triage with AI. Here are the real results after 6 months — including what still needs humans.
P.08Traditional test suites break when outputs are non-deterministic. Here's how we test AI-powered features — from LLM output validation to regression testing for prompt changes, with real frameworks and examples.
