WordPress 6.9 added assertEqualHTML(), which removes a whole category of brittle test failures caused by formatting-only HTML differences. I reviewed the implementation and mapped out concrete migration patterns for plugin and theme test suites.
If your test suite has ever failed because of a whitespace difference in rendered HTML, this is for you.
Agentic AI moves fast. A few lines of code, a powerful LLM, and suddenly an agent is doing something that looks impressive. The rapid iteration is addictive, but it leads to a development style I call "vibe coding" -- tweak a prompt, rerun, and if the output feels right, ship it.
This works for a demo. It is a recipe for disaster in production.
I built a DDEV add-on that runs Playwright checks against local MCP endpoints using internal DDEV DNS names like web. This solves flaky localhost-based testing and gives one command for repeatable MCP smoke tests.
I distilled WordPress 6.9.1 RC1 into a compatibility checklist for plugins and themes before the maintenance release landed. I also packaged the checklist and notes into a small repo so teams can clone it and wire it into their own QA flow.
