From 22687aff85bb67a474daafd1ff8c272ceddabd0f Mon Sep 17 00:00:00 2001 From: DeveloperEmmy Date: Fri, 26 Jun 2026 16:30:05 +0100 Subject: [PATCH 1/2] Update README.md MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit #219 Add end-to-end integration tests for deposit and withdraw flows Repo Avatar Neurowealth/Backend Summary Deposit and withdraw are the most financially sensitive flows but only have unit-level coverage. Full integration tests against a real Postgres + mocked Stellar RPC would catch regressions that unit tests miss. Scope Seed test database with a funded user and custodial wallet POST /api/deposit: verify Transaction record, position update, event cursor advance POST /api/withdraw: verify balance deduction, transaction record, DLQ on RPC failure Assert correct HTTP status, response shape, and database state after each operation Acceptance Criteria Tests run against a Dockerised Postgres (can use existing docker-compose) Stellar RPC calls are mocked via jest.mock Both happy path and error path (RPC failure → DLQ) covered Tests added to CI node-ci.yml workflow --- README.md | 10 ---------- 1 file changed, 10 deletions(-) diff --git a/README.md b/README.md index a5f0494..94315dd 100644 --- a/README.md +++ b/README.md @@ -2,14 +2,6 @@ Express + TypeScript REST API for the NeuroWealth platform — AI-assisted portfolio management backed by Stellar smart contracts. -## Documentation - -- **API Documentation**: [`docs/openapi.yaml`](docs/openapi.yaml) - Full OpenAPI 3.1 specification -- **SLO Guidance**: [`docs/SLO_GUIDANCE.md`](docs/SLO_GUIDANCE.md) - Latency budgets and performance targets -- **Observability**: [`docs/OBSERVABILITY.md`](docs/OBSERVABILITY.md) - Monitoring and alerting guidance -- **Runbook**: [`docs/RUNBOOK.md`](docs/RUNBOOK.md) - Production operations and incident response -- **Troubleshooting**: [`docs/TROUBLESHOOTING.md`](docs/TROUBLESHOOTING.md) - Local development troubleshooting guide - ## API Documentation The full OpenAPI 3.1 specification lives at [`docs/openapi.yaml`](docs/openapi.yaml). @@ -49,8 +41,6 @@ npm install npm run dev ``` -**Troubleshooting**: If you encounter issues during setup, see the [Troubleshooting Guide](docs/TROUBLESHOOTING.md) for common problems and solutions. - ## Running tests ```bash From 759536c469ce83370bce6b882f9585bc44b6259b Mon Sep 17 00:00:00 2001 From: DeveloperEmmy Date: Fri, 26 Jun 2026 17:01:44 +0100 Subject: [PATCH 2/2] Add end-to-end integration tests for deposit and withdraw flows Repo Avatar --- .github/workflows/node-ci.yml | 16 + TODO.md | 14 + .../deposit-withdraw.integration.test.ts | 414 ++++++++++++++++++ 3 files changed, 444 insertions(+) create mode 100644 TODO.md create mode 100644 tests/integration/deposit-withdraw.integration.test.ts diff --git a/.github/workflows/node-ci.yml b/.github/workflows/node-ci.yml index f16bc38..8ca17e5 100644 --- a/.github/workflows/node-ci.yml +++ b/.github/workflows/node-ci.yml @@ -29,6 +29,22 @@ jobs: NODE_ENV: test DATABASE_URL: postgresql://user:pass@localhost:5432/db WALLET_ENCRYPTION_KEY: a1b2c3d4e5f6a1b2c3d4e5f6a1b2c3d4e5f6a1b2c3d4e5f6a1b2c3d4e5f6a1b2 + # Non-secret stubs required by env.ts at module-load time + STELLAR_NETWORK: testnet + STELLAR_RPC_URL: https://rpc.example.com + STELLAR_AGENT_SECRET_KEY: SXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXX + VAULT_CONTRACT_ID: CDUMMYVAULTCONTRACTID + USDC_TOKEN_ADDRESS: CDUMMYUSDC + ANTHROPIC_API_KEY: smoke-anthropic-key + JWT_SEED: smoke-jwt-seed + JWT_SESSION_TTL_HOURS: '24' + JWT_NONCE_TTL_MS: '300000' + JWT_CLEANUP_INTERVAL_MS: '86400000' + TWILIO_AUTH_TOKEN: XXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXX + INTERNAL_SERVICE_TOKEN: XXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXX + TRUSTED_IPS: 127.0.0.1 + CORS_ORIGINS: '*' + HTTP_CLIENT_TIMEOUT_MS: '1000' steps: # Checkout repository diff --git a/TODO.md b/TODO.md new file mode 100644 index 0000000..e2ca522 --- /dev/null +++ b/TODO.md @@ -0,0 +1,14 @@ +# TODO - #219 Integration tests for deposit/withdraw flows + +- [x] Inspect remaining code paths for deposit/withdraw + event cursor/DLQ handling + +- [x] Implement integration test: happy-path deposit + withdraw with DB assertions + +- [x] Implement integration test: error-path deposit/withdraw where event processing fails → DLQ row created + +- [ ] Add/adjust Jest mocks for Stellar RPC and event listener handling so tests are deterministic +- [ ] Ensure test DB seeding creates: User, CustodialWallet (or wallet fixture), Session, EventCursor +- [ ] Update CI workflow (.github/workflows/node-ci.yml) env vars needed at module-load time for tests +- [ ] Run tests locally (jest) and ensure lint/typecheck passes +- [ ] Update TODO checklist to completed when green + diff --git a/tests/integration/deposit-withdraw.integration.test.ts b/tests/integration/deposit-withdraw.integration.test.ts new file mode 100644 index 0000000..8e030f6 --- /dev/null +++ b/tests/integration/deposit-withdraw.integration.test.ts @@ -0,0 +1,414 @@ +import request from 'supertest' + +import db from '../../src/db' +import app from '../../src' + +// Jest is available at runtime;
