Frontend Testing

Read the testing policy for the package that owns the changed tests:

• web/: web/docs/test.md owns Web test boundaries, environments, and commands.
• packages/dify-ui/: packages/dify-ui/docs/testing.md owns primitive test boundaries, environments, Storybook, and commands.

This skill adds no parallel policy or check sequence. Follow the selected owner's requirements, including its validation commands. Recommend deleting low-value tests as readily as adding missing behavior coverage, and report the contract verified and any material verification gap.
