Summary

Config/CI improvements from a test-automation audit. No test-code rewrites in this PR.

Changes

  • test:ci-utils — wires the orphaned node --test files (e2e/utils/*.test.js, 42 tests) into CI via a new ci/run-ci-utils step in .github/actions/test/action.yaml.
  • check-types:e2e — adds a tsc -p e2e/tsconfig.json --noEmit script. Not wired into CI: the e2e TypeScript code has 66 pre-existing type errors and has never been type-checked; wiring it would break CI. Tracked as follow-up.
  • Coverage — extends collectCoverageFrom to src/app/**/*.ts and src/renderer/**/*.{ts,tsx} (the renderer UI was previously excluded), and adds a coverageThreshold of 50/40/40/50 (measured 56.61/47.56/44.3/56.67).
  • Node version — aligns the two e2e workflows from 22.x to 24.x to match .nvmrc (v24.16.0).

Verification

  • npx jest --coverage → exit 0, 80 suites / 1359 tests pass
  • npm run test:ci-utils → 42 tests, 0 fail
  • npx tsc -p e2e/tsconfig.json --noEmit → 66 pre-existing errors (why it's not wired)

Change Impact: 🟢 Low

Regression Risk: Changes affect test coverage and CI configuration only. They do not modify production logic or critical user flows.

QA Recommendation: Manual QA is not required. Rely on the reported automated test results and CI validation.

Generated by CodeRabbitAI

- Add test:ci-utils script and wire into CI test action (42 tests)
- Add check-types:e2e script (not wired: 66 pre-existing type errors)
- Extend collectCoverageFrom to src/app and src/renderer .tsx
- Add coverageThreshold 50/40/40/50
- Align e2e workflows to Node 24.x (matches .nvmrc v24.16.0)

Estimated code review effort: 2 (Simple) | ~10 minutes

Merge Risk: 🔵 Low · up to f285c

The PR adds a coverage threshold, but CI does not currently collect coverage for the unit-test run, so that guard is not enforced. The change is otherwise mergeable with explicit owner awareness or follow-up.

Quote the utility-test glob.

The command currently leaves e2e/utils/*.test.js to the configured shell. Quote the glob so Node receives the pattern consistently across CI shells. Node.js 24 supports glob arguments and recommends quoting them to reduce shell-dependent behavior. (nodejs.org)

Proposed fix
-    "test:ci-utils": "node --test e2e/utils/*.test.js",
+    "test:ci-utils": "node --test \"e2e/utils/*.test.js\"",

Enable coverage for CI unit tests.

The CI action runs npm run test:unit, which invokes jest without coverage. Run npm run test:unit-coverage so coverageThreshold is enforced.
