Migrate To Rstest
Migrate Jest or Vitest projects to Rstest. Use when asked to move from Jest/Vitest to Rstest, replace `jest`/`vi` APIs with `@rstest/core`, translate config into `rstest.config.ts`, update scripts/coverage/setup/mocks/snapshots/projects, or diagnose migration failures caused by Rstest's Rsbuild/Rspack execution model or version skew.

Declared compatibility
Compatibility is declared by the source manifest. End-to-end runtime verification is coming, see below.
We're building live execution health for every listing: tool-call success rate, median latency, uptime, and last-checked timestamps, measured, not self-reported. It isn't live yet, so we don't show numbers we can't stand behind.

Migrate to Rstest
Goal
Migrate Jest/Vitest tests and config to Rstest with minimal behavior changes. Use the current Rstest migration docs for exact mappings; this skill adds scope, dependency, and cleanup guardrails.
Workflow
- Detect runner and scope (
references/detect-test-framework.md). - Run dependency/version gates (
references/dependency-install-gate.md). - Read only the needed deltas: Jest, Vitest, and/or global API replacement.
- Migrate scripts/config/setup before tests; prefer adapters or Rsbuild/Rspack config fixes before editing test bodies.
- Validate discovery/types/run, fixing failures in this order: dependency skew, config/resolver, setup/env/coverage, mocks/timers/snapshots, test bodies.
- After the scope is green, remove only scope-local legacy files and devDeps no remaining scope uses.
- Summarize changes, kept legacy files, unsupported fields, and TODOs.
Guardrails
- Keep the smallest viable scope; do not broaden a monorepo migration or bulk-rewrite tests when config/setup fixes are plausible.
- Do not change production behavior, assertions, test names, scenarios, or coverage thresholds to make migration pass.
- No
jest/vishims or aliases; rewrite call sites to Rstest APIs (references/global-api-migration.md). - Do not silently drop unknown config fields; verify or report them as unsupported.
High-risk Rstest deltas
rstest/rstest runis single-run; watch mode isrstest --watchorrstest watch.globalsdefaults tofalse; if globals remain, setglobals: trueand add@rstest/core/globalstypes.- Rstest runs on Rsbuild/Rspack. Use
references/dependency-install-gate.mdfor latest-only APIs, coverage providers, adapters, plugins, and toolchain-version fallbacks.
Escalate before large edits
If the next fix requires many test edits or production source changes, stop and report: why smaller fixes failed, options, risks, and the recommended path.
