​Created by Roomote. Follow up by mentioning @roomote, in the web UI, or in Discord.

What changed

  • Add a source-unit Vitest lane that excludes only the built-artifact smoke test and preserves complete source coverage.
  • Add a focused dist lane for dist_assets.spec.ts, the only extension test that reads real bundle output.
  • Give each lane a cache-correct Turbo task: unit work depends on types build and excludes the dist test input, while artifact validation depends on bundle and retains default package inputs.
  • Keep the existing full test and test:coverage commands unchanged for local and current CI compatibility.

Why this change was made

The four-area split proposed in #115 assumed stable ownership boundaries but would require risky hand-maintained cross-area input graphs. Current inspection found a safer boundary: one 40-test file consumes built artifacts, while the other 475 test files do not. Isolating that contract removes the bundle dependency from the source-unit lane without narrowing source inputs or weakening coverage.

Profiling also disproved issue #116's original assumption that every root-level test requires dist/. The corrected measured acceptance criteria retain the issue history without making this PR close against its stale body.

Impact

There is no product-facing change. A forced local bundle costs about 40 seconds, while the artifact smoke itself takes about 435ms. The artifact assertions import no source, so enabling coverage for that lane would create an empty or redundant report; the unit lane already preserves the complete 467-file LCOV result at 22,823/30,227 covered lines. Once #117/#118 wire these lanes into CI, ordinary source changes can run equivalent unit coverage without rebuilding the extension bundle.

Post-#1611 cold non-core coverage measured about 2m59s on Ubuntu and 9m40s on Windows; same-SHA cache hits completed in 1–2s. The focused dist lane passes all 40 assertions, the full suite passes all 8,277 tests, and lint, formatting, type checking, and resolved Turbo graphs pass.

Related: #115, #116, #117, #118.

📝 Summary

Summary by CodeRabbit

  • Tests
    • Added dedicated commands for running unit tests, distribution validation tests, and unit-test coverage reports.
    • Unit and distribution test runs now use separate configurations, allowing each test suite to run independently.
    • Unit-test coverage results are stored separately from existing coverage reports.
  • Chores
    • Updated project task orchestration to support the new test workflows and associated coverage outputs.

Walkthrough

The change adds dedicated Vitest configurations, npm scripts, and Turbo tasks for unit tests and distribution asset tests. Unit coverage writes to coverage/unit, while distribution tests run only __tests__/dist_assets.spec.ts after the bundle task.

Changes

Test scope separation

Layer / File(s) Summary
Vitest test configurations
src/vitest.unit.config.ts, src/vitest.dist.config.ts
The unit configuration excludes distribution asset tests and writes coverage to coverage/unit. The distribution configuration includes only __tests__/dist_assets.spec.ts.
Test scripts and Turbo tasks
src/package.json, src/turbo.json
New npm scripts and Turbo tasks run unit tests, unit coverage, and distribution tests with their dedicated configurations. Turbo declares the required build dependencies and unit coverage output.

Produce and cache the required dist coverage.

test:dist does not pass --coverage, so Vitest does not produce a coverage report. The dist configuration also does not set coverage.reportsDirectory, and the Turbo task does not cache coverage/dist.

Proposed coverage fix
 			test: {
 				include: ["__tests__/dist_assets.spec.ts"],
+				coverage: {
+					reportsDirectory: "coverage/dist",
+				},
 			},

-		"test:dist": "vitest run --config vitest.dist.config.ts",
+		"test:dist": "vitest run --config vitest.dist.config.ts --coverage",

 		"test:dist": {
 			"dependsOn": ["bundle"],
+			"outputs": ["coverage/dist/**"]

The requested dist coverage task is intentionally not added because this lane validates emitted files rather than imported source. Fresh profiling showed only dist_assets.spec.ts requires dist/; its 40 assertions contribute no source coverage, while test:coverage:unit already preserves the full prior LCOV result exactly (467 files, 22,823/30,227 covered lines). Adding --coverage and caching coverage/dist/** would therefore create an empty or redundant artifact and add overhead without improving coverage integrity.

The focused lane still has the required correctness dependency: pnpm turbo run test:dist --filter=zoo-code --dry-run resolves zoo-code#test:dist -> zoo-code#bundle, and the real lane passes 40/40 assertions in 438ms. Full pnpm test also passes 8,277 tests. Commit 8f4b0cd documents this coverage ownership in the config.

Issue #116's broader assumption was recorded as superseded by measured criteria at #116 (comment). I am leaving this thread unresolved because the suggested coverage change was deliberately declined rather than implemented.

Pushed 8f4b0cd56 and refreshed the PR metadata to reference, not close, stale issue #116. The issue now has measured replacement criteria, and the CodeRabbit thread has a concrete evidence-based reply explaining why dist coverage would be empty or redundant. Focused smoke (40/40), full tests (8,277), lint, formatting, type checks, and Turbo dependency resolution pass. The declined CodeRabbit thread remains unresolved by design.
