Testing Library
A straightforward skill for React Testing Library that gets you up and running with component testing in Claude Code. It covers the current production setup with version 16.x and user-event 14.x, supporting both Vitest and Jest configurations. The skill has solid adoption with 207 installs and passes all three major security audits. If you're writing React tests and want Claude to understand RTL patterns and best practices without having to explain the API every time, this does the job. It's maintained by jezweb as part of a larger skill collection that's gotten decent traction on GitHub.
