Somewhere in the last year, "do we need an MCP server?" joined the list of questions that arrive in a brief before anyone has said what the thing is for. It is usually framed as MCP vs API, as though the Model Context Protocol were a newer kind of AP...

📝Every QA engineer and developer knows the drill: You find a bug. You manually write down steps to reproduce, take screenshots, and format a ticket for Jira or GitHub. Then, you open your IDE and write the exact same steps all over again in code for ...

AI-Driven Playwright E2E Tests From One Reference Doc
Writing E2E Tests With One Doc Instead of New Tooling We had a growing monorepo with two frontend apps and zero end-to-end coverage. The blocker was never Playwright itself. It was that every new feature meant babysitting an AI agent through the te...

The Waiting Problem Behind Most Flaky Suites
Most of us have had a test suite that passed locally, failed once in CI, then passed on the rerun until nobody trusted it as evidence of anything. This is about why that happens, and why one framework's default behavior removes most of it. Flake Is ...

Playwright vs TWD: A Frontend Developer's Honest Comparison
I had both Playwrighthttps://playwright.dev/docs/intro and TWDtwd.dev pointed at the same small app for a working day. Same backend, same UI, the same bugs to chase. The point wasn't to declare a winner. It was to notice what each one feels like to l...
