I love finding simple tools that solve boring problems. More patterns on the AI QA Architect blog: anton.qa #AIQAArchitect #Playwright

Before: Export cookies by hand. Paste them into a file. Repeat every day. After: One command. Your test reads what the browser holds. The machine does the work.

I used to copy cookies out of the browser by hand. It felt like manual labor. Then I found one flag that turns the Playwright CLI into a data pipe. 🧵

I wrote the full breakdown of how this changes your QA pipeline: 🔗 anton.qa/blog/posts/the… #AIQAArchitect #Playwright

The real win isn't skipping a script. It's "Shared State." Before: Two browsers. Two truths. After: Same browser. Same session. Same bug. When an agent finds a bug, you see it in your own browser. Immediately.

AI agents still can't open a browser and log in. That's the "Login Gap." It kills automation. But this month, two teams at Microsoft shipped a fix. Not one feature. Two. Same pattern. Two paths. 🧵

I just published Native Drag-and-Drop Automation Arrives in Playwright MCP medium.com/p/native-drag-…

I'm Anton — former Apple SDET, now Lead Software Engineer in Test. One project tripled test count in 18 months and cut deployment time in half. Cutting drag-and-drop workarounds was a big part of that. 🔗 anton.qa/blog/posts/nat… #AIQAArchitect

npx playwright install --with-deps That gets you browser_drop and all the other new tools. No extra setup.

playwright-mcp v0.0.71 shipped. browser_drop is now an MCP tool. Drag-and-drop. No JS injection hacks. No third-party library. Native Playwright Locator.drop — callable from any MCP client. 🧵

If you're building AI agent QA, this changes how you think about "the browser" in your test pipeline. Not a headless box. A shared surface between human and agent. Full architecture breakdown Wednesday on anton.qa — how it works, how to use it, and what most teams miss. #AIQAArchitect

This isn't two features. It's one standard being settled. Playwright built the bridge. Then they made it walkable without a build step. Before: every team hacked authenticated-browser access themselves. After: it's a Chrome extension and a one-liner. That's what converging standards look like.

Two Microsoft teams shipped the same MCP pattern in one month. Playwright core: browser.bind() in v1.59. playwright-cli: MCP Bridge extension in v0.1.5. Same goal. Different code. One message: Playwright is the browser backend for AI agents now. 🧵
