📝 Walkthrough

Walkthrough

A new unit test suite is added for the getFileIcon utility function. The tests cover multiple scenarios including exact filename matches (package.json, Dockerfile, .gitignore, eslint.config.js, vitest.config.ts, .env), compound extensions (types.d.ts, utils.test.ts, utils.spec.js, Button.stories.tsx), simple extensions (.js, .ts, .vue, .json, .sh, .py, .rs, .png, .tar), and unknown file types. The suite verifies precedence rules where exact filename matches take priority over extensions, and compound extensions take priority over simple extensions. The tests use Vitest's describe and it functions to validate the icon mapping behaviour.
