Writing or changing Vitest or React Testing Library tests under `web/` or
by langgeniusFree
Description
frontend-testing is an agent skill from the Dify repository by LangGenius, listed on skills.sh. It applies when someone writes or changes Vitest or React Testing Library tests under the web folder or the dify-ui package, or explicitly asks for frontend test work. It does not add its own testing policy. Instead it points to the policy of whichever package owns the tests: the web folder's test document covers the web test boundaries, environments and commands, and the dify-ui testing document covers primitive test boundaries, environments, Storybook and commands. The agent follows the owner's requirements, including its validation commands. The skill also advises that low-value tests should be deleted as readily as missing behaviour coverage is added, and that the contract verified and any material verification gap should be reported. A skill is a SKILL.md file of instructions that an AI agent loads when a task calls for it. It is free and open source, and the skills.sh listing shows all three security audits passing.…
