Remove test console warnings and add CI enforcement by Copilot · Pull Request #7820 · primer/react

Copilot · 2026-05-07T20:33:03Z

Changelog

New

Added a shared @primer/vitest-config workspace package for the common Vitest console-enforcement setup.
Added package-local config/vitest/setup.ts entrypoints so each package can consume the shared Vitest setup without relying on a top-level setup script path.

Changed

Updated AnchoredOverlay to re-sync CSS anchor-positioning state when an external anchorRef DOM node is replaced while the overlay remains open.
Preserved existing internal renderAnchor behavior while fixing the React 19 external-anchor remount case that caused anchor-name and position-anchor to fall out of sync.
Added an inline code comment documenting the React 19-specific external anchor replacement behavior.
Updated package Vitest configs to use the new shared setup package through package-local TypeScript setup entrypoints.
Added the minimum TypeScript project includes needed for lint/type-aware parsing of the renamed setup files.
Resolved merge conflicts in the node Vitest configs by keeping both the setup.ts entrypoints from this PR and the upstream detectAsyncLeaks: true updates.
Scoped @primer/doc-gen's declaration build back to src/**/* so the new config/vitest/setup.ts entrypoint remains available for tooling without being pulled into the published build and breaking CI with TS6059.

Removed

Removed the top-level shared Vitest setup script at script/vitest/setup.ts.

Testing & Reviewing

Analyzed the failing GitHub Actions test (react-19) job logs for run 25577112553, job 75087602292.
Reproduced the original failure locally against packages/react/src/ActionMenu/ActionMenu.test.tsx.
Verified the AnchoredOverlay fix with:
- npx vitest --config vitest.config.browser.mts run src/AnchoredOverlay/AnchoredOverlay.test.tsx
- npx vitest --config vitest.config.browser.mts run src/ActionMenu/ActionMenu.test.tsx
Verified the shared Vitest setup refactor with:
- npm run lint -- --no-cache
- npm run type-check
- cd packages/styled-react && npx vitest --run src/__tests__/exports.test.ts
- cd packages/react && npx vitest --config vitest.config.browser.mts run src/AnchoredOverlay/AnchoredOverlay.test.tsx
Verified the follow-up setup.ts rename and TS config updates with:
- cd packages/react && npx vitest --config vitest.config.mts run src/__tests__/exports.test.ts
- cd packages/styled-react && npx vitest --config vitest.config.ts run src/__tests__/exports.test.ts
- cd packages/doc-gen && npx vitest --config vitest.config.mts run --passWithNoTests
- cd packages/postcss-preset-primer && npx vitest --config vitest.config.ts run --passWithNoTests
- npm run lint -- --no-cache packages/vitest-config/setup.ts packages/react/config/vitest/setup.ts packages/styled-react/config/vitest/setup.ts packages/doc-gen/config/vitest/setup.ts packages/postcss-preset-primer/config/vitest/setup.ts packages/react/vitest.config.mts packages/react/vitest.config.browser.mts packages/styled-react/vitest.config.ts packages/styled-react/vitest.config.browser.ts packages/doc-gen/vitest.config.mts packages/postcss-preset-primer/vitest.config.ts
- npx tsc -p packages/vitest-config/tsconfig.json --noEmit
- npx tsc -p packages/doc-gen/tsconfig.json --noEmit
- npx tsc -p packages/postcss-preset-primer/tsconfig.json --noEmit
Resolved the PR merge conflicts by merging origin/main and re-validating the conflicted Vitest config files with:
- npm run lint -- --no-cache packages/react/vitest.config.mts packages/styled-react/vitest.config.ts packages/doc-gen/vitest.config.mts packages/postcss-preset-primer/vitest.config.ts
- cd packages/react && npx vitest --config vitest.config.mts run src/__tests__/exports.test.ts
- cd packages/doc-gen && npx vitest --config vitest.config.mts run
Analyzed the later failing GitHub Actions CI logs for run 25677748363 and traced the regression to the @primer/doc-gen build.
Verified the CI follow-up fix with:
- cd packages/doc-gen && npm run build
- npm run build
- npm run type-check
- cd packages/styled-react && npx vitest --config vitest.config.ts run src/__tests__/exports.test.ts
Ran secret scanning and final automated review / CodeQL validation.

@copilot fix CI, it is currently broken. Don't submit changes for review until CI is green

Fixed in b0e2fcd. Local validation is green (CI=true npm run test, npm run lint -- --no-cache, npm run type-check, npm run build, npm run lint:css, npm run format:diff -- --cache=false). The new GitHub Actions runs are currently action_required with no jobs, so they need approval before CI can turn green; I have not submitted the PR for review.

@copilot fix failing CI

Addressed in 228e350. The CI failure was the @primer/doc-gen build pulling config/vitest/setup.ts into the declaration build; scoping tsconfig.build.json back to src/**/* fixes that. Local validation is green with cd packages/doc-gen && npm run build, npm run build, npm run type-check, and cd packages/styled-react && npx vitest --config vitest.config.ts run src/__tests__/exports.test.ts. The new GitHub Actions runs are currently action_required, so they need approval before CI can re-run.

@copilot instead of allowing these messages, update the corresponding test to make assertion on these logs being emitted or fix the underlying test

Addressed in 4434a49. I removed the shared allowlist, updated the affected tests to explicitly assert the expected warnings/errors (or render valid inputs), and fixed UnderlineNav overflow prop forwarding so leadingVisual no longer leaks to the DOM. Validated with targeted CI=true browser Vitest runs for the touched suites plus lint on the changed files.

Pull request overview

This PR centralizes Vitest console-enforcement across workspaces (to prevent CI-only console noise), updates multiple test suites to eliminate warnings under React 19/browser Vitest, and adjusts AnchoredOverlay to re-sync CSS anchor-positioning when an externally managed anchor DOM node is replaced while the overlay remains open.

Changes:

Introduces a shared @primer/vitest-config package for CI console enforcement and wires it into each workspace via package-local config/vitest/setup.ts.
Fixes AnchoredOverlay CSS anchor-positioning behavior for React 19 external-anchor replacement, and updates related tests.
Cleans up various component/test behaviors that triggered console warnings (focus/act timing, ResizeObserver mocking, deprecated nested-button render, ref cleanup semantics).

@copilot defer to the original implementation and commit the result

Addressed in 618e2ea. I restored the original state-driven footer layout implementation in Dialog and re-ran the targeted Dialog browser tests plus lint.

Addressed in 44d5a49. The LabelGroup overlay test now uses afterEach to always restore the console.error spy and ResizeObserver mock, and I re-ran lint plus the targeted browser Vitest file.
