execution and quality gates + +## Decision + +Implemented a dedicated test execution workflow (`.github/workflows/test.yml`) that runs all test suites in parallel stages with enforced coverage gates and comprehensive reporting. + +## Rationale + +### Architecture: Parallel Test Stages +- **Build stage** (15 min): Single, cached build shared by all test jobs +- **Test stages** (6 parallel jobs): Unit, Architecture, bUnit, Integration, Aspire, E2E — all run simultaneously +- **Coverage stage** (dependent on coverage tests): Aggregates coverage, enforces 80% threshold +- **Report stage** (final): Publishes test results to GitHub Actions check suite + +**Why parallel:** +- 6 independent test suites with no shared state → safe parallelization +- Reduces total execution time from ~30 minutes (sequential) to ~15 minutes (parallel) +- Each job has its own cache miss/hit, dependency resolution, build +- Minimal redundancy: single build job caches NuGet packages for all subsequent jobs + +### Coverage Gates + +**Threshold:** 80% line coverage (or per-project basis) + +**Implementation:** +- Coverlet collector enabled on Unit, bUnit, Integration, and Aspire tests +- ReportGenerator aggregates `.cobertura.xml` reports from all projects +- `Summary.json` parsed for pass/fail logic (warns if <80%, fails if explicitly configured) +- Architecture tests excluded from coverage collection (NetArchTest + Coverlet conflict noted in original CI) +- Coverage report uploaded as artifact for visibility + +**Why 80%:** +- Industry standard for mature codebases +- Balances velocity (not overly strict) with quality (not permissive) +- Can be adjusted per-project via test configuration if needed + +### Test Framework Support + +| Test Type | Framework | Coverage | Notes | +|-----------|-----------|----------|-------| +| Unit | xUnit v3 | ✅ Coverlet | Basic business logic | +| Architecture | NetArchTest | ❌ Excluded | Conflicts with Coverlet | +| Blazor Component | bUnit | ✅ Coverlet | UI component logic | +| Integration | xUnit + TestContainers | ✅ Coverlet | Requires MongoDB service | +| Aspire | xUnit | ✅ Coverlet | Service topology & health checks | +| E2E | Playwright + xUnit | ❌ Not applicable | Browser automation, no coverage | + +### MongoDB in CI + +**Integration tests** spawn a MongoDB 7.0 service via GitHub Actions `services`: +```yaml +services: + mongodb: + image: mongo:7.0 + ports: [27017:27017] + health-cmd: mongosh + health-interval: 10s +``` + +- Service automatically health-checked before test execution +- `MONGODB_CONNECTION_STRING` injected as env var +- TestContainers inside tests can override or use provided service +- Automatic cleanup when job completes + +**Why service-based (not Testcontainers in CI):** +- Simpler for CI environment (no Docker-in-Docker complexity) +- Faster startup (image cached in runner) +- Replicates dev environment (`testcontainers` used in local dev) + +### Artifact Strategy + +**Test Results (always):** +- Each job uploads `.trx` files (TRX = XML test result format) +- Named by job: `unit-test-results`, `integration-test-results`, etc. +- EnricoMi action parses and publishes to GitHub check suite + +**Coverage Reports (conditional, on test completion):** +- HTML report (for manual inspection in artifact browser) +- Cobertura XML (for Codecov integration) +- JSON summary (for automated pass/fail logic) +- Uploaded to `coverage-reports` artifact + +**Why separate uploads:** +- Faster downloads (users can grab just what they need) +- Cleaner artifact browser in Actions +- Easier to debug specific test suite failures + +### Error Handling & Reporting + +1. **Per-job failure:** Job explicitly exits with code 1 if tests fail +2. **Timeout protection:** Each job has timeout (10-20 min depending on type) +3. **Coverage check:** Warns (not fails) if below 80% — can be enforced later via branch protection +4. **Final report job:** Aggregates all job statuses, generates GitHub Step Summary for visibility + +### Performance Targets + +| Stage | Expected Time | Rationale | +|-------|---|---| +| Build | 5-10 min | Restore + build Release config, cached deps | +| Test jobs (parallel) | 5-10 min | Most tests complete in <5 min | +| Coverage aggregation | 1-2 min | Report generation, Codecov upload | +| Total | 12-15 min | Target: <15 min for full suite | + +## Trade-offs & Considerations + +### ❌ What We Don't Do +- **Parallel test execution within a job** — `.trx` logging conflicts in same directory; separate jobs avoid this +- **E2E coverage measurement** — Playwright tests measure user workflows, not code coverage +- **Hard coverage gate (fail)** — Currently warns; can enforce via branch protection if stricter policy desired +- **Historical trend tracking** — Coverage reports are per-run; Codecov integration handles this + +### ✅ What We Can Improve Later +- [ ] Coverage thresholds per-project (stricter on core, looser on UI) +- [ ] Parallel test runners within a job (xUnit `/maxParallel:4` if stable) +- [ ] E2E test matrix (Chrome, Firefox, Safari via Playwright) +- [ ] Performance baselines (store timing data, alert on regression) +- [ ] Test report HTML badge for README (via artifact-to-blob service) + +## Dependencies & Preconditions + +- All test projects must have `true` property (allows auto-discovery) +- Global.json specifies .NET 10 — setup-dotnet@v5 reads this +- `Directory.Packages.props` must define all NuGet versions (centralized) +- Test projects must support `--collect:"XPlat Code Coverage"` (xUnit + Coverlet) + +## Success Metrics + +✅ **Achieved:** +1. All 6 test suites run in parallel (no sequential blocking) +2. Coverage collected and reported (80%+ enforced as warning) +3. Test results published to GitHub check suite (via EnricoMi action) +4.
