Write, review, filter, mock, and debug Core unit tests with the repository's installed Vitest 5 configuration. Use for tests under Core's Vitest include paths, `vi.mock`/spies/timers, jsdom component tests, coverage output, focused reruns, or unit-test failures. Do not use for browser E2E flows or async Next.js Server Components.
Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.
What the file says
# Vitest in Core Use the repository harness as the source of truth. Core currently resolves Vitest 5.0.5 from `bun.lock`; verify the exact version before relying on a newly introduced API. ## Authority and test surface Read these before changing tests or configuration: - `vitest.config.mts` — include globs, aliases, Node default environment, timeouts, mock clearing, setup, and the supported V8 coverage provider. - `tests/setup/unit-env.ts` — safe env defaults and browser shims. - `scripts/verify/unit-tests.mjs` — the full unit gate and platform behavior. - `docs/ai/rules/testing.md` — repository-wide test and CI policy. - `.next-docs/01-app/02-guides/testing/vitest.mdx` when testing Next.js code. Do not use `bun test`; that selects Bun's test runner. Use Vitest through the committed scripts or `bunx vitest`. ## Commands ```bash # Full CI-equivalent unit suite with the supported V8 coverage provider bun run test:unit # Focused file or directory while iterating bunx vitest run tests/unit/path/to/example.test.ts # Focused test name bunx vitest run tests/unit/path/to/example.test.ts -t "expected behavior" # Watch a focused surface …

How to install
mdr add asymmetric-al/core/vitest@sha256:91caac7cd888a236The line at the top of this page pins the label git:20261021.3c4a499, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
