# Smoke and Regression Procedure

This page defines the standard checks before and after backend/frontend/scanner
changes.

## Local/Pre-Push Rules

For frontend or backend code changes:

1. Run focused tests for the touched area.
2. Run typecheck.
3. Run `git diff --check`.
4. Bump backend and frontend patch versions together if a build/deploy will be pushed.
5. For payment/scanner changes, run the relevant smoke script before pushing.

Docs-only changes do not require version bumps.

## Backend Smoke Scripts

Backend smoke scripts live in:

```text
backend/scripts/smoke/
```

Current scripts:

| Script | Purpose |
|---|---|
| `backend-health.sh` | Basic API health/version target check. |
| `auth-basic.sh` | Basic auth behavior. |
| `addresses-basic.sh` | Address APIs. |
| `bsc-testnet-payment-registry.sh` | Chain 97 token/RPC registry sanity. |
| `confirmation-thresholds.sh` | Confirmation threshold APIs/settings. |
| `funds-ledger-repo.sh` | Funds ledger repository behavior. |
| `marketplace-e2e-notifications.sh` | Buyer/seller E2E smoke with notification assertions, concurrency levels, and reports. |
| `marketplace-request-budget.sh` | Purchase request budget validation. |
| `rn-intent.sh` | Request Network / in-house intent creation smoke. |
| `rn-webhook.sh` | Webhook shape/signature flow. |
| `user-admin-postgres.sh` | Admin user persistence. |
| `user-dependencies.sh` | User dependency smoke. |

Run against dev:

```bash
cd ~/CascadeProjects/escrow/backend
BASE_URL=https://dev.amn.gg bash scripts/smoke/bsc-testnet-payment-registry.sh
```

Two-round marketplace smoke:

```bash
cd ~/CascadeProjects/escrow/backend
BASE_URL=https://dev.amn.gg \
PAYMENT_MODE=status \
CONCURRENCY_LEVELS=1 \
ROUNDS=2 \
bash scripts/smoke/marketplace-e2e-notifications.sh
```

Use `PAYMENT_MODE=live` when the BSC Testnet wallet has gas and canonical
tUSDT. The runner writes reports to ignored `backend/tmp/e2e-reports/`; see
[[Marketplace E2E Smoke Runner]].

Run against local:

```bash
BASE_URL=http://127.0.0.1:5001 bash scripts/smoke/backend-health.sh
```

## Focused Automated Tests

Payment/scanner backend focus:

```bash
cd ~/CascadeProjects/escrow/backend
npm test -- --runTestsByPath \
  __tests__/rn-in-house-checkout.test.ts \
  __tests__/decentralized-payment-verifier.test.ts \
  __tests__/amn-pay-adapter-intent.test.ts \
  --runInBand
```

Marketplace/delivery focus:

```bash
npm test -- --runTestsByPath \
  __tests__/simple-marketplace.test.ts \
  __tests__/marketplace-idor.test.ts \
  __tests__/escrow-state-machine.test.ts \
  --runInBand
```

Frontend checkout focus:

```bash
cd ~/CascadeProjects/escrow/frontend
npx tsc --noEmit --ignoreDeprecations 6.0
npx eslint src/web3/config.ts src/web3/types.ts src/sections/payment/checkout/rn-in-house-checkout-view.tsx
npm run build
```

Scanner focus:

```bash
cd ~/CascadeProjects/escrow/scanner
go test ./...
```

## CI/Deploy Verification

Use Woodpecker with token from the local environment:

```bash
export WOODPECKER_SERVER=https://ci.tbs.amn.gg
export WOODPECKER_TOKEN=<local secret>
```

Never commit or paste the token into docs.

Poll latest pipelines by repo id:

| Repo | Woodpecker repo id | Expected pipeline |
|---|---:|---|
| backend | `5` | typecheck, build-and-deploy, notify |
| frontend | `7` | build-and-deploy, notify |
| scanner | `8` | build/test/deploy |

Required post-deploy checks:

```bash
curl -fsS https://dev.amn.gg/api/version
curl -fsS -I https://dev.amn.gg/
ssh -i <ssh-key> root@<dev-host> \
  "docker ps --format '{{.Names}}\t{{.Image}}\t{{.Status}}' | grep -E 'escrow-(backend|frontend|scanner)'"
```

Expected:

- `/api/version` matches package version for backend/frontend build pair;
- frontend root returns HTTP 200;
- backend/frontend/scanner containers are healthy;
- corresponding Woodpecker pipelines are `success`.

## Regression Evidence Format

For every test run, record:

```markdown
### YYYY-MM-DD - <short summary>

- Target: `https://dev.amn.gg`
- Versions: backend/frontend/scanner
- CI: backend #, frontend #, scanner #
- Commands:
  - `...`
- Live scenarios:
  - run id
  - request ids
  - payment ids
  - tx hashes
- Result: pass/fail/blocked
- Residual risk:
  - ...
```

## When To Stop a Release

Stop or roll back if any P0 condition fails:

- payment can be marked paid without correct chain/token/destination/amount evidence;
- buyer cannot complete a valid payment;
- non-buyer can confirm delivery;
- frontend cannot connect/switch to the chain returned by backend checkout;
- backend/frontend/scanner registry mismatch exists;
- CI deploy reports success but live containers are not healthy;
- secrets appear in git status, logs, docs, or CI output.
