ci: add Codecov bundle and test analytics - #605
Merged
Conversation
Adds two additive Codecov analysis planes alongside the existing coverage upload; none replace an existing repository-native gate. Test Analytics: every suite that already produces a Playwright/Vitest JUnit file now uploads it via codecov/codecov-action (report_type: test_results, disable_search, explicit files path) instead of the deprecated codecov/test-results-action. Vitest runs once per Node version with two reporters (json + junit) in the same invocation, no second test run. Uploads use !cancelled() so a real failure still uploads its result. Fixes a pre-existing gap where Storybook's --junit output (jest-junit's own default, <cwd>/junit.xml) was never captured by the existing artifact upload. Bundle Analysis: @codecov/vite-plugin runs last in vite.config.ts, gated by an explicit CODECOV_BUNDLE_ANALYSIS flag scoped only to the build job's existing analyze step (no third Vite build, token scoped to that one step). Stable bundle name, PR head SHA attribution, telemetry disabled, codecov.yml status kept informational until a real size baseline exists. Verified empirically against the real production build (PWA injectManifest, manual chunking, every existing plugin) despite the plugin's peerDependencies range not yet listing Vite 8.
…adToken vite.config.ts assigned uploadToken: string | undefined into a slot typed uploadToken?: string; under this repo's exactOptionalPropertyTypes that forbids passing undefined for an omittable key. Omit the key entirely when no token is present (fork PRs) instead.

📝 WalkthroughWalkthroughThe CI workflow now generates and uploads JUnit reports for test suites, publishes results to Codecov, and supports opt-in Codecov Bundle Analysis through the Vite build. Workflow policy tests and CI documentation cover the new behavior. ChangesCodecov reporting integration
Estimated code review effort: 3 (Moderate) | ~25 minutes Merge Risk: 🔵 Low · up to This change adds Codecov test and bundle reporting without blocking CI uploads. The remaining risk is that the Codecov token is available more broadly than the bundle-analysis build requires, increasing CI secret exposure and unnecessary cache invalidation.

Explicit outputFile paths for both Vitest reporters in the one CI invocation, rather than letting junit inherit vitest.config.ts's own default. Scope CODECOV_* vars to the build task's own env in turbo.json instead of globalEnv, so they aren't hashed into and available to every unrelated Turbo task. Add a data-driven test that verifies each CI job's Codecov test-analytics upload uses its own correct files/flags/name, not just an aggregate step count. Add the QNBS-v3 rationale comment to playwright.config.ts's junit reporter block. Correct docs/CI.md on two mechanics: the plugin appends an output-format suffix to the configured bundle name, and Bundle Analysis's non-blocking behavior comes from the Vite plugin's own unset emitError argument, not fail_ci_if_error (which only applies to codecov-action).

…l gating CodeAnt correctly flagged that continue-on-error on the desktop Lighthouse step swallows its accessibility/CLS error assertions at job/merge level. That behavior is pre-existing (unchanged by this consolidation), not a #608 regression, but the comments/docs this PR touches stated it ambiguously. Now explicit: mobile Lighthouse accessibility/CLS is a blocking required gate; desktop's is still evaluated and can fail the step itself, but continue-on-error keeps that from failing the job, and promotion to blocking remains gated on the existing 5-consecutive-main-run exit criterion. Also softened a "no wall-clock cost" claim to state what's actually measured: fits the post-#605 baseline's critical-path slack, not a universal guarantee.

#608) * ci: consolidate VRT + Lighthouse into one Browser Quality job Both jobs already ran in parallel off the workflow's critical path but each paid its own checkout/setup/build-artifact-download; merging them into one job removes that duplication. Real measurement: VRT spent 57 of its 73s (78%) on setup versus 8s of actual test execution. Each phase still runs independently via if: ${{ !cancelled() }} so a VRT or mobile-Lighthouse failure never skips a later phase's own diagnostic evidence, matching what two separate jobs would have produced; only desktop Lighthouse keeps its existing continue-on-error soft-fail. * docs: distinguish desktop Lighthouse step-level failure from job-level gating CodeAnt correctly flagged that continue-on-error on the desktop Lighthouse step swallows its accessibility/CLS error assertions at job/merge level. That behavior is pre-existing (unchanged by this consolidation), not a #608 regression, but the comments/docs this PR touches stated it ambiguously.

Summary
Adds two additive Codecov analysis planes alongside the existing coverage upload. Neither replaces an existing repository-native gate (
bundle:budget, coverage thresholds, the coverage ratchet, first-attempt-failure policy, or any existing artifact upload).Test Analytics — verified end-to-end with real CI ingestion logs, not just green steps
Every suite that already produces a Playwright/Vitest JUnit file now uploads it via
codecov/codecov-action(report_type: test_results,disable_search: true, explicitfiles:path) — never the deprecatedcodecov/test-results-action. Vitest runs once per Node version with two reporters in the same invocation, both output paths explicit in the command itself (--outputFile.json=test-results.json --outputFile.junit=reports/junit.xml— never relying onvitest.config.ts's own reporter-tuple default, which could drift independently of this exact command). Every upload runs onif: ${{ !cancelled() }}(not the defaultsuccess()), so a real test failure still uploads its result.unit-node22reports/junit.xmlFound 1 test_results files to report→reports/junit.xml,Sending upload (318760 bytes)unit-node24reports/junit.xmle2etests/e2e/results/junit.xmle2e-deeptests/e2e/results/junit.xmlstorybooktest-results/storybook-junit.xmlFound 1 test_results files to report→test-results/storybook-junit.xml(2875 bytes), confirms the pre-existing-gap fix below actually worksvrttests/e2e/results/junit.xmlFound and fixed a pre-existing gap while wiring this up: Storybook's
--junitflag usesjest-junitunder the hood, whose default output path is<cwd>/junit.xmlat the repo root — outside every path the existing artifact-upload step captures. Traced this throughjest-junit's actual source; fixed withJEST_JUNIT_OUTPUT_FILE=test-results/storybook-junit.xml. Confirmed working via the real CI log above, not just locally.Test coverage strengthened after review: the initial aggregate-count test (
report_typeappears exactly 5 times, etc.) could pass with five miswired uploads all targeting one suite. Replaced/supplemented with a data-drivenit.eachcoveringquality/e2e/e2e-deep/storybook/vrtindividually — each asserts its own exactfiles:,flags:,name:, plus the shared pin/!cancelled()/report_type/disable_search. Verified this actually catches the exact regression class it's meant to: deliberately duplicated one suite's flag onto another and confirmed the test failed, then restored and confirmed it passes again.Bundle Analysis — real finding: the upload does not currently reach Codecov
@codecov/vite-pluginruns as the last plugin invite.config.ts(Codecov's own requirement), gated by an explicitCODECOV_BUNDLE_ANALYSIS=trueenv var scoped only to thebuildjob's existinganalyzestep. Configured bundle name is the stableworldscript-studio-web— the plugin itself appends the output format, so the name actually visible on Codecov's dashboard would beworldscript-studio-web-esm(this repo only emitsesoutput).uploadOverrides.shauses the PR head SHA viaCODECOV_BUNDLE_SHA.telemetry: falsedisables the plugin's own telemetry about itself only.Real CI evidence from the diagnostic run (commit
72b2c777) shows the upload itself failing, even though thebuildjob reportssuccess:This is not a code defect — the token, SHA, and CI-provider detection all resolved correctly up to that point, and the request the plugin makes is well-formed (independently re-verified against the plugin's own compiled source: correct fixed endpoint, correct
Authorization: token <uploadToken>header,slugtaken straight from GitHub Actions' ownGITHUB_REPOSITORY). The build step showssuccessregardless because@codecov/vite-plugincalls the underlyingOutput.write()without its optionalemitErrorargument (verified against the plugin's own source), so provider/auth/upload failures are caught internally and never fail the build — confirmed correct, matching the "must never turn a Codecov outage into a false build failure" requirement, but it also means a green step is not proof of ingestion, exactly as flagged during review.Update: Bundle Analysis was subsequently enabled on the Codecov dashboard for this repo, and the
buildjob was re-run diagnostically on this same head afterward — the identical three-attemptget-pre-signed-url404 reproduced. Since the rerun happened well after the dashboard change, propagation delay is no longer a plausible explanation. Coverage and Test Analytics ingestion (the sameCODECOV_TOKEN, the same repo) continue to work correctly throughout. The precise provider/account/backend condition causing the 404 is not established — we can rule out a source-side regression, but do not have Codecov server-side logs proving which server-side condition is responsible. The failure has been submitted to Codecov via their Bundle Analysis feedback channel. Per this PR's owncodecov.yml(bundle_analysis.status: informational), this remains non-blocking and is not a merge gate; it's tracked as an open, external follow-up rather than resolved here.Real GitHub-hosted CI timing (the ANALYZE build step, not my earlier constrained-local-hardware numbers): 34.4s total,
rollup-plugin-visualizer generateBundle23.6s (69%),@codecov/vite-plugin writeBundle5.8s (17% — this is mostly the three failed pre-signed-URL retry attempts, not real upload time). Materially faster than the ~126s I measured locally, confirming that number was hardware-relative, not CI-predictive.Vite 8 / Rolldown compatibility — verified, not assumed; tracked as a known accepted gap
@codecov/vite-plugin@2.0.1declarespeerDependencies: { vite: "4.x || 5.x || 6.x" }. This repo runs Vite 8 with Rolldown. No pnpm override,packageExtensionsbroadening, or Vite downgrade was applied to hide this — the plugin pin and the repo's real Vite/Rolldown version are both untouched from their natural values. Verified empirically instead:npm install --legacy-peer-deps+vite build) against plain Vite 8.2.1 — clean build.injectManifest(2503 precache entries), manual chunking, Tailwind, React, workspace aliases, the conditional visualizer — clean build, correct service worker,dist/bundle-analysis.htmlproduced, zero source maps, zero secret leakage.Opened #606 as the narrow, durable follow-up to revalidate (or remove) this exception once
@codecov/vite-pluginofficially declares Vite 8 support — not buried in a merged PR's history.Security
CODECOV_TOKENis never assigned at workflow or job level (verified: noenv:block exists at either scope inci.yml, andturbo.jsonscopes it to thebuildtask's ownenv, notglobalEnv, after review caught thatglobalEnvwould have exposed it — and its value — to every unrelated Turbo task's hash and runtime environment) — only inside the exact CI steps and Turbo task that need it. Enforced by executable tests.pnpm auditon the new dependency found one pre-existing high-severity advisory (extract-zipvia@lhci/cli→puppeteer-core) — unrelated to@codecov/vite-plugin, already present onmainbefore this PR.codecov/codecov-action) usefail_ci_if_error: false— a Codecov outage must never turn a correct build into a false CI failure. Bundle Analysis has no such input; its non-blocking behavior comes from the Vite plugin's own internal error-swallowing (see above), not fromfail_ci_if_error.Validation
