+# AetherForge Test Suite
+
+One command runs everything:
+
+```bat
+test.bat
+```
+
+Or with PowerShell directly:
+
+```powershell
+.\scripts\test-suite.ps1
+```
+
+## Phases
+
+| Phase | What it runs | Location |
+|-------|----------------|----------|
+| 1 | Go server unit + integration tests | `server/` |
+| 2 | Go agent tests | `agent/` |
+| 3 | Fusion module compile check | `fusion/` |
+| 4 | Frontend unit tests (Vitest) | `server/web/` |
+| 5 | Frontend production build | `server/web/` |
+| 6 | Server binary compile | `server/` |
+| 7 | Agent binary compile | `agent/` |
+| 8 | E2E smoke (Playwright) | `server/web/e2e/` — starts temp server |
+
+## Run individual suites
+
+```bat
+cd server && go test ./...
+cd agent && go test ./...
+cd server\web && npm test
+cd server\web && npm run test:e2e
+```
+
+## E2E only (server already running)
+
+```bat
+set AETHERFORGE_URL=http://127.0.0.1:8989
+cd server\web && npm run test:e2e
+```
+
+## Adding tests
+
+- **Go:** `*_test.go` next to the code under test
+- **Frontend:** `src/**/*.test.ts` (Vitest)
+- **E2E:** `server/web/e2e/*.spec.ts` (Playwright)
+
+Coverage areas: forge/fusion, auth, DB, pool reconnect, API routes, fleet filters, preflight validation, media crypto roundtrip, dashboard login smoke.
