# Testing signals — withastro/astro > Canonical page: https://codevetter.com/unpack/astro/testing-signals # Testing signals — withastro/astro Scanned commit 4c1470a7f907fe678ef5e7dceaa972ca83d297da (2026-10-02). Generated by codevetter codevetter 1.15.0 on 2026-10-02. Source inspection; upstream code and tests were not executed. Tests and CI were inspected, not executed; a test's existence is not a passing result. Core tests use node:test with built dist imports, while browser tests use Playwright and benchmark tooling uses Vitest. Inspected cases cover persistence, action behavior, origin-check composition, provider finalization, and hydration recovery. CI defines lint, type, cross-platform test, browser, smoke, and benchmark jobs. Inspection was bounded, so coverage completeness and untested repository-wide behavior remain unestablished. - Core unit-test guidance requires node:test and node:assert/strict, placement under package test/units, and imports from built dist output. — [reference/unit-testing.md#L5-16](https://github.com/withastro/astro/blob/4c1470a7f907fe678ef5e7dceaa972ca83d297da/reference/unit-testing.md#L5-L16) - Astro's test script runs unit, integration, and type suites; unit tests use strip-types and teardown, integration tests use parallel execution, and browser suites run Chrome and Firefox configurations. — [packages/astro/package.json#L115-124](https://github.com/withastro/astro/blob/4c1470a7f907fe678ef5e7dceaa972ca83d297da/packages/astro/package.json#L115-L124) - astro-scripts test uses node:test.run(), supports match/only/parallel/setup/teardown options, and selects process isolation for parallel tests versus no isolation for sequential tests. — [scripts/cmd/test.js#L14-39](https://github.com/withastro/astro/blob/4c1470a7f907fe678ef5e7dceaa972ca83d297da/scripts/cmd/test.js#L14-L39) [scripts/cmd/test.js#L112-130](https://github.com/withastro/astro/blob/4c1470a7f907fe678ef5e7dceaa972ca83d297da/scripts/cmd/test.js#L112-L130) - Store-persistence tests assert restored data after updates and include chunked entry records crossing part boundaries. — [packages/astro/test/units/content-layer/store-persistence.test.ts#L14-35](https://github.com/withastro/astro/blob/4c1470a7f907fe678ef5e7dceaa972ca83d297da/packages/astro/test/units/content-layer/store-persistence.test.ts#L14-L35) [packages/astro/test/units/content-layer/store-persistence.test.ts#L221-238](https://github.com/withastro/astro/blob/4c1470a7f907fe678ef5e7dceaa972ca83d297da/packages/astro/test/units/content-layer/store-persistence.test.ts#L221-L238) - Action integration tests create a fixture with a unique outDir, start dev, build a test-adapter app, and assert invalid direct invocation and form-action page results. — [packages/astro/test/actions.test.ts#L10-28](https://github.com/withastro/astro/blob/4c1470a7f907fe678ef5e7dceaa972ca83d297da/packages/astro/test/actions.test.ts#L10-L28) [packages/astro/test/actions.test.ts#L54-81](https://github.com/withastro/astro/blob/4c1470a7f907fe678ef5e7dceaa972ca83d297da/packages/astro/test/actions.test.ts#L54-L81) - Action origin tests mount Hono actions() before middleware() and assert that cross-origin requests return 403 without executing the action, while same-origin requests execute it. — [packages/astro/test/units/actions/action-origin-check.test.ts#L66-104](https://github.com/withastro/astro/blob/4c1470a7f907fe678ef5e7dceaa972ca83d297da/packages/astro/test/units/actions/action-origin-check.test.ts#L66-L104) - Endpoint origin tests mount pages() without middleware() and assert cross-origin rejection before endpoint execution; provider-finalization tests assert a 500 when a finalizer rejects. — [packages/astro/test/units/hono/pages-origin-check.test.ts#L42-80](https://github.com/withastro/astro/blob/4c1470a7f907fe678ef5e7dceaa972ca83d297da/packages/astro/test/units/hono/pages-origin-check.test.ts#L42-L80) [packages/astro/test/units/fetch/provider-finalize.test.ts#L6-28](https://github.com/withastro/astro/blob/4c1470a7f907fe678ef5e7dceaa972ca83d297da/packages/astro/test/units/fetch/provider-finalize.test.ts#L6-L28) - Playwright hydration tests abort the first component import and assert recovery without reload; persistent failure tests assert one hydration-error event and no page errors. — [packages/astro/e2e/astro-island-hydration-error.test.ts#L40-70](https://github.com/withastro/astro/blob/4c1470a7f907fe678ef5e7dceaa972ca83d297da/packages/astro/e2e/astro-island-hydration-error.test.ts#L40-L70) [packages/astro/e2e/astro-island-hydration-error.test.ts#L73-101](https://github.com/withastro/astro/blob/4c1470a7f907fe678ef5e7dceaa972ca83d297da/packages/astro/e2e/astro-island-hydration-error.test.ts#L73-L101) - CI's Astro/integration matrix covers Ubuntu with Node 22 and 24, and macOS/Windows with Node 24 after explicit exclusions; separate jobs execute E2E and smoke scripts. — [.github/workflows/ci.yml#L153-175](https://github.com/withastro/astro/blob/4c1470a7f907fe678ef5e7dceaa972ca83d297da/.github/workflows/ci.yml#L153-L175) [.github/workflows/ci.yml#L285-322](https://github.com/withastro/astro/blob/4c1470a7f907fe678ef5e7dceaa972ca83d297da/.github/workflows/ci.yml#L285-L322) [.github/workflows/ci.yml#L324-334](https://github.com/withastro/astro/blob/4c1470a7f907fe678ef5e7dceaa972ca83d297da/.github/workflows/ci.yml#L324-L334) [.github/workflows/ci.yml#L391-395](https://github.com/withastro/astro/blob/4c1470a7f907fe678ef5e7dceaa972ca83d297da/.github/workflows/ci.yml#L391-L395) - CI includes Biome, lint:ci, publint, and typecheck; Linux ts-plugin test failures are converted to warnings, so that step is not a strict passing gate. — [.github/workflows/ci.yml#L99-111](https://github.com/withastro/astro/blob/4c1470a7f907fe678ef5e7dceaa972ca83d297da/.github/workflows/ci.yml#L99-L111) [.github/workflows/ci.yml#L140-151](https://github.com/withastro/astro/blob/4c1470a7f907fe678ef5e7dceaa972ca83d297da/.github/workflows/ci.yml#L140-L151) [.github/workflows/ci.yml#L274-279](https://github.com/withastro/astro/blob/4c1470a7f907fe678ef5e7dceaa972ca83d297da/.github/workflows/ci.yml#L274-L279) - Example diagnostics run test:check-examples;
