#58 Write End-to-End Integration Tests for Core API Flows FIXED

[felladaniel36-hash]

Findings

1. API Route Architecture Gap: The core Express application in server.js originally defined all public routes at the root level (/register, /lookup, /users, /federation). However, the integration requirements specifically demanded interacting with /api/v1/register.
2. Database Constraint Reliance: The backend logic relies directly on SQLite's internal UNIQUE primary key constraints on the username column to identify and reject duplicate user registration attempts. Existing test suites in the repository were purely unit tests that mocked sqlite3 and generic-pool, meaning there was no prior test validating how the Express routes, real SQLite database engine, and global error-handling middleware interact during constraint violations.
3. Husky Pre-commit Hook & ESLint Interaction: The repository enforces a strict Husky pre-commit hook running lint-staged. When new test files are added without explicit ESLint environment directives, ESLint rejects standard Jest global identifiers (jest, describe, test, expect, beforeAll, afterAll) as undefined variables (no-undef), causing Husky to abort commits and throw the Git: [STARTED] Backing up original state... rollback alert in VS Code.

Fix Features

1. Seamless /api/v1/* Route Aliasing:
   • Upgraded the Express route definitions in server.js to accept path arrays (e.g., app.post(['/register', '/api/v1/register'], ...)). This satisfies the new integration acceptance criteria while maintaining 100% backward compatibility for legacy API callers and existing unit test suites.
2. Automated End-to-End Lifecycle Integration Suite:
   • Created a comprehensive integration test file (stellar-payment-platform/integration.test.js) powered by supertest that validates the full user journey:
     • Successful Registration: Hits POST /api/v1/register with a valid Ed25519 Stellar public key and verifies a 201 Created status return.
     • Multifaceted Querying: Validates user retrieval via exact address lookup (GET /api/v1/lookup?address=...), partial search (GET /api/v1/lookup?search=...), and federation resolution (GET /api/v1/federation?q=...), asserting expected 200 OK JSON responses.
     • Duplicate Prevention: Attempts to register an existing username with a new valid Stellar address, ensuring the database UNIQUE constraint triggers correctly and yields the expected 409 Conflict (Username already registered) JSON payload.
3. Database State Cleanliness & Automated Clearing:
   • Configured beforeAll and afterAll test hooks to automatically execute DELETE FROM username_registry to guarantee mock database rows are cleared before and after test executions.
   • Assigned a dedicated mock database file (mock-integration-registrations.db) via process.env.DB_PATH to ensure complete isolation from other environments, with automated unlinking/teardown upon test completion.
4. 100% ESLint & Husky Hook Compliance:
   • Added /* eslint-env jest */ at the top of integration.test.js and removed unused block variables to fully satisfy the linting engine, ensuring clean, unblocked Git commits and pull request creation.
