* chore(ci): reduce CI runner-minutes by consolidating parity and narrowing cross-platform
Scope-resolution parity previously spawned 9 separate GitHub Actions jobs
(one per migrated language), each doing full checkout + npm ci + build for
a single test file. Consolidate into one job running scripts/run-parity.ts
which loops through all migrated languages sequentially — same coverage,
~45 fewer runner-minutes of redundant setup per PR.
Cross-platform (Windows/macOS) previously ran the full 373-file test suite.
Narrow to 45 platform-sensitive files (native LadybugDB, process spawning,
path separators, worker threads, filesystem behavior). Full suite still runs
on Ubuntu with coverage.
Also adds 2 missing lbug integration tests (lbug-orphan-sidecar-recovery,
lbug-readonly-init) to the sequential lbug-db vitest project where they
belong, and rewrites TESTING.md to document all test lanes.
* fix: address code review findings on parity and cross-platform scripts
- Capture stderr in run-parity.ts (vitest writes diagnostics to stderr)
- Lower per-invocation timeout from 5min to 60s to stay within CI job limit
- Add --language flag validation (error on missing value)
- Add timeout diagnostic to run-cross-platform.ts catch block
- Add analyze-wal-checkpoint-failure.test.ts to lbug-db sequential project
- Expand cross-platform list: parser-loader, pipeline, pipeline-graph-golden,
setup-skills, cli/tool-no-index-stderr (51 files, was 45)
* fix: add shell:true for Windows npx resolution and simplify fs import
execFileSync('npx', ...) fails with ENOENT on Windows because npx is
npx.cmd — shell:true resolves this. Also replaces dynamic await
import('fs') with static import, and fixes timeout detection to use
err.killed instead of err.code.
* fix(ci): raise parity per-invocation timeout to 120s and job timeout to 30min
TypeScript and C++ resolver tests take 60-90s on CI runners, exceeding
the 60s per-invocation timeout. Raise to 120s. Also bump the job-level
timeout from 25 to 30 minutes for margin (realistic total is ~11 min).
* fix(ci): raise parity per-invocation timeout to 180s for C++ resolver
C++ resolver tests take 130-150s on CI runners due to template
metaprogramming, ADL, and SFINAE fixture volume. 120s was still too
tight. Realistic total across all 9 languages is ~12 min, well under
the 30-min job timeout.
* fix(ci): use stdio inherit for parity — no per-invocation timeout
Switch from piped stdio with per-invocation timeouts to stdio: 'inherit'.
Vitest output streams to CI console in real time, making failures
immediately visible. The CI job-level timeout (30 min) is the only
guard — no more artificial per-invocation timeouts that cut off slow
resolver tests like C++ (which genuinely takes 3+ minutes).

Pre-commit hook
A husky pre-commit hook (.husky/pre-commit) runs automatically on every git commit:
- Formatting —
lint-stagedruns prettier on staged files gitnexus-web/files staged →tsc -b --noEmitgitnexus/files staged →tsc --noEmit
Tests do not run in the pre-commit hook — they run in CI (ci-tests.yml) only.
Skip with git commit --no-verify (use sparingly).
Vitest projects
gitnexus/vitest.config.ts defines three projects for safety isolation:
| Project | Files | Parallelism | Purpose |
|---|---|---|---|
lbug-db |
Native LadybugDB integration tests (explicit list) | Sequential | Prevents file-lock conflicts from native mmap addon |
cli-e2e |
skills-e2e.test.ts |
Sequential | CLI process spawning requires serial execution |
default |
Everything else | Parallel | Fast execution for pure logic and parser tests |
When adding a new test that uses native LadybugDB (@ladybugdb/core), add it to the lbug-db project's explicit include list and the default project's exclude list.
Test categories
- Unit — Pure logic, parsers, graph/query helpers; fast; no network.
- Integration — Real combinations (filesystem, MCP wiring, larger pipelines) as already organized under
gitnexus/test/integration. - Resolver / parity — Language-specific call-resolution tests in
test/integration/resolvers/. - E2E (web) — Critical user paths only; prefer
data-testidattributes for stable selectors. Tests run against real backend (gitnexus serve) and Vite dev server.
Scope-resolution parity
Migrated languages (listed in MIGRATED_LANGUAGES in src/core/ingestion/registry-primary-flag.ts) are tested in both legacy and registry-primary modes on every PR.
For each migrated language, CI runs the resolver test file twice:
REGISTRY_PRIMARY_<LANG>=0— legacy DAG pathREGISTRY_PRIMARY_<LANG>=1— registry-primary path
Both must pass. Known legacy gaps are listed in LEGACY_RESOLVER_PARITY_EXPECTED_FAILURES in test/integration/resolvers/helpers.ts and are automatically skipped in legacy mode.
Adding a language to MIGRATED_LANGUAGES automatically enrolls it in parity — no workflow or config edit needed. The test file must exist at test/integration/resolvers/<slug>.test.ts.
Run parity locally: cd gitnexus && npm run test:parity
Run for a single language: cd gitnexus && npx tsx scripts/run-parity.ts --language python
Cross-platform testing
Windows and macOS CI runs only the platform-sensitive test subset (~50 files out of 373). The full suite runs on Ubuntu.
The subset is defined in gitnexus/scripts/cross-platform-tests.ts and includes:
- Platform-specific logic — tests with
process.platformguards, path.sep behavior, EPERM/EBUSY error classification - Native LadybugDB — all
lbug-*integration tests (N-API addon with known platform-varying behavior) - Process spawning / CLI — tests using real
child_process.spawn, shell quoting, CLI invocations - Worker threads — tests spawning real
worker_threads - Native addon loading — tree-sitter grammar loading smoke tests
- Filesystem behavior — CRLF handling, directory walking, symlinks
When adding a platform-sensitive test, add it to the appropriate section in scripts/cross-platform-tests.ts.
Confirming no tests are orphaned
Every test file matches one of the three vitest projects. To verify:
cd gitnexus
npx vitest list 2>/dev/null | wc -l # should match total test count
To check the cross-platform list is up to date, run npm run test:cross-platform — it fails fast if any listed file is missing.
CI integration
GitHub Actions (.github/workflows/ci.yml) orchestrate:
| Workflow | Jobs | Purpose |
|---|---|---|
ci-quality.yml |
format, lint, typecheck, typecheck-web, workflow-convention | Code quality gates |
ci-tests.yml |
ubuntu/coverage, cross-platform (Win/Mac), packaged-install-smoke | Full suite + coverage on Ubuntu; platform-sensitive subset on Win/Mac |
ci-scope-parity.yml |
discover, parity | Scope-resolution parity for all migrated languages |
ci-e2e.yml |
e2e (chromium) | Playwright E2E, gated on gitnexus-web/** changes |
The CI Gate job in ci.yml is the single required check for branch protection. It requires quality, tests, e2e, and scope-parity to all pass.
Regression testing
Re-run the full relevant suite when:
- Prompt or agent-behavior documentation changes (if tests encode behavior)
- Model or embedding-related code paths change
- Graph schema, query contracts, or MCP tool shapes change
- Dependencies with parsing or runtime impact upgrade
User acceptance / beta (optional)
For staged releases or UI betas: deploy to a staging environment, collect structured feedback, watch errors and latency, then iterate before a wider release.
