Query Picker for Testing Library

Inspect and generate Testing Library queries for any element on the page.

Query Picker for Testing Library — MV3 Edition A DevTools panel extension that helps you generate the best query statements for projects using Testing Library (React Testing Library, DOM Testing Library, etc.). ⚠️ This is an independent, community-maintained version — not an official testing-library product. The original Testing Playground extension was removed from the Chrome Web Store due to Manifest V2 deprecation. This project is a Manifest V3 migration and bug-fix rebuild, based on the original MIT-licensed source code. ✨ Improvements over the original: - Fixed a crash that occurred when "Block third-party cookies" was enabled - Fixed script injection failures in certain scenarios - Fixed build compatibility issues on Windows - Fully adapted to Manifest V3, meeting Chrome's latest security requirements Features: - Select any element on the page - Automatically generates recommended Testing Library queries (getByRole, getByText, etc.) - One-click copy to clipboard - Supports Playwright query syntax This extension is completely free and open source, based on the original Testing Playground project (MIT License). If the official team releases an MV3 version in the future, we recommend switching back to it.
