# Automated Test‑Suite Overview
|
||
|
||
This document enumerates **every automated check** executed by the Stella Ops
|
||
CI pipeline, from unit level to chaos experiments. It is intended for
|
||
contributors who need to extend coverage or diagnose failures.
|
||
|
||
> **Build parameters** – values such as `{{ dotnet }}` (runtime) and
|
||
> `{{ angular }}` (UI framework) are injected at build time.

## Layer map
|
||
|
||
| Layer | Tooling | Entry‑point | Frequency |
|
||
|-------|---------|-------------|-----------|
|
||
| **1. Unit** | `xUnit` (<code>dotnet test</code>) | `*.Tests.csproj` | per PR / push |
|
||
| **2. Property‑based** | `FsCheck` | `SbomPropertyTests` | per PR |
|
||
| **3. Integration (API)** | `Testcontainers` suite | `test/Api.Integration` | per PR + nightly |
|
||
| **4. Integration (DB‑merge)** | in‑memory Mongo + Redis | `FeedMerge.Integration` | per PR |
|
||
| **5. Contract (gRPC)** | `Buf breaking` | `buf.yaml` files | per PR |
|
||
| **6. Front‑end unit** | `Jest` | `ui/src/**/*.spec.ts` | per PR |
|
||
| **7. Front‑end E2E** | `Playwright` | `ui/e2e/**` | nightly |
|
||
| **8. Lighthouse perf / a11y** | `lighthouse-ci` (Chrome headless) | `ui/dist/index.html` | nightly |
|
||
| **9. Load** | `k6` scripted scenarios | `k6/*.js` | nightly |
|
||
| **10. Chaos CPU / OOM** | `pumba` | Docker Compose overlay | weekly |
|
||
| **11. Dependency scanning** | `Trivy fs` + `dotnet list package --vuln` | root | per PR |
|
||
| **12. License compliance** | `LicenceFinder` | root | per PR |
|
||
| **13. SBOM reproducibility** | `in‑toto attestation` diff | GitLab job | release tags |

## Quality gates
|
||
|
||
| Metric | Budget | Gate |
|
||
|--------|--------|------|
|
||
| API unit coverage | ≥ 85 % lines | PR merge |
|
||
| API response P95 | ≤ 120 ms | nightly alert |
|
||
| Δ‑SBOM warm scan P95 (4 vCPU) | ≤ 5 s | nightly alert |
|
||
| Lighthouse performance score | ≥ 90 | nightly alert |
|
||
| Lighthouse accessibility score | ≥ 95 | nightly alert |
|
||
| k6 sustained RPS drop | < 5 % vs baseline | nightly alert |

||
## Local runner
|
||
|
||
```bash
|
||
# minimal run: unit + property + frontend tests
|
||
./scripts/dev-test.sh
|
||
|
||
# full stack incl. Playwright and lighthouse
|
||
./scripts/dev-test.sh --full
|
||
````
|
||
|
||
The script spins up MongoDB/Redis via Testcontainers and requires:
|
||
|
||
* Docker ≥ 25
|
||
* Node 20 (for Jest/Playwright)

|
||
|
||
## Adding a new test layer
|
||
|
||
1. Extend `scripts/dev-test.sh` so local contributors get the layer by default.
|
||
2. Add a dedicated GitLab job in `.gitlab-ci.yml` (stage `test` or `nightly`).
|
||
3. Register the job in `docs/19_TEST_SUITE_OVERVIEW.md` *and* list its metric
|
||
in `docs/metrics/README.md`.
