--- description: globs: tests/** alwaysApply: false --- - Always use vitest (never use jest or any other testing framework) - Always pin **Vitest ≥ 3.1** (or `latest`) in `devDependencies` so `vi.stubGlobal`, `unstubGlobals`, and other modern helpers exist. - Use `environment: 'node'` and **Node 22+** so the built-in `fetch` and `Headers` classes are available without polyfills. - Trim or normalise strings before comparing multi-line Markdown/HTML: `expect(result.trim())` rather than raw literals with trailing spaces. - Always place async fetch stubs **inside** each test (or `beforeEach`) so they do not bleed unexpected data into other cases.
