Spent 7 years automating tests the hard way. Then Claude Code finished a week of my work in 2 hours. I write about what actually works — so you don't waste time figuring it out alone.

The first time I tried to get an agent to do real exploratory testing against staging, I spent two days building a bridge and about forty minutes testing. Staging sat behind a VPN. The seeded database was reachable from one subnet. The browsers I actually trusted — pinned versions, matching the CI image — lived in a...

The task was trivial: add an item to the cart, go to checkout, click Place...
Catching the Anti-Patterns Claude Code Writes Into Your Tests The test was green. That was the problem. I'd asked Claude Code to add coverage for a checkout flow, it produced a tidy Playwright spec, the suite passed, and I almost merged it. Then I actually read the diff. The "test"...
Claude Code writes mediocre tests without context. Here's the four-file setup — CLAUDE.md and three Skills — that turns it into a QA engineer who knows your standards....
