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 (dotnet test)	*.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	Feedser.Integration (vulnerability ingest/merge/export service)	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

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

# 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.
