The implementation is loaded from the optional `@rstest/typecheck` package, which must match the core version. Type assertions and lightweight static registration APIs are imported from `@rstest/typecheck`; core registration imports also remain recognized. This tracks the companion editor compatibility work required by the core repository's contribution guidelines.\n\nThe implementation discovers `*.test-d.ts` / `*.spec-d.ts` files, statically collects direct `describe` / `test` / `it` calls, and runs the project's compiler without executing the test file. `listTests({ includeTaskLocation: true })` returns these cases through the existing `ListedTest` shape. Reporter case results carry `meta.typecheck: true`; file results additionally carry the checker name and version.\n\nPlease cover:\n- Discover and run configured type tests through `createRstest` / `listTests` / `run`, including mixed runtime/type projects and `typecheck.only`.\n- Preserve source locations, nested names, and compiler diagnostics. Expression titles are their source text; files without static registrations have a single `[typecheck]` case.\n- Explain that name/file filters select reported cases while the full tsconfig remains checked. `.only`, `.skip`, parameterized and conditional registration modifiers are unsupported and produce collection errors.\n- Type tests run on the host for browser projects as well. They do not execute setup files, runtime hooks, snapshots, retries, or coverage; editor actions should respect those limits.\n- Type testing does not support watch mode. Use one-shot run actions for type cases; the core reports an error for watch plus typecheck.\n- Recognize `@rstest/typecheck` registration imports and preserve actionable missing-package/version-mismatch errors. Ordinary runtime projects do not require this package.\n- Verify `onlyFailures` across mixed runtime/type projects: core shares file failure history and falls back to a full run once no recorded failures remain. Explicit file/name filters take precedence.\n- Respect `bail` results: later type cases and projects are not reported after the run-wide limit; the compiler invocation already started for a project still checks the full tsconfig.\n- Include discovery/run/result mapping tests against the core PR build before release.\n\nCore PR: https://github.com/web-infra-dev/rstest/pull/1984","author":{"url":"https://github.com/9aoy","@type":"Person","name":"9aoy"},"datePublished":"2026-10-22T10:01:23Z","url":"https://github.com/rstackjs/rstack-editor/issues/111"}
