Combine Integration Test Infrastructure and TypeScript Fixes

Progress

• Initial exploration and understanding of the repository
• Fix TypeScript compilation errors in src/database/client.ts
  • Add missing pool initialization line
  • Use type-only import for QueryResult
  • Properly type error handler
  • Use PoolClient type for transaction callback
• Add pg and @types/pg dependencies to package.json
• Update jest.integration.config.js to reference setup/teardown files
• Create integration test infrastructure files:
  • jest.integration.setup.ts - Database initialization
  • jest.integration.teardown.ts - Database cleanup
  • src/database/test-seeder.ts - Test data seeding utilities with proper types
• Create integration test example:
  • src/database/__tests__/integration/database-client.integration.test.ts
• Create GitHub Actions workflow:
  • .github/workflows/integration-tests.yml with security permissions
• Verify TypeScript compilation passes for database client
• Address initial code review feedback:
  • Improve type safety in test-seeder (use Agent, CapabilityVector types)
  • Wrap cleanAll() in transaction for atomicity
  • Use PoolClient type for transaction callback
  • Improve error message clarity
• Security scan (CodeQL):
  • Fix workflow permissions issue
  • No remaining security vulnerabilities

  • Update cleanAll() to use TRUNCATE TABLE CASCADE for performance
  • Clarify comment about multi-table cleanup
  • Update Node.js version to 18.18 in workflow
  • Add timeout and failure handling to PostgreSQL readiness loop
• Final validation - all files compile successfully

Summary

All changes from PR #91 (integration test infrastructure) and PR #92 (TypeScript fixes) have been successfully combined into this single PR. All review feedback has been addressed. TypeScript compilation passes, code review feedback has been addressed, and security scan shows no vulnerabilities.

Original prompt

Summary

Combine the integration test workflow from PR #91 and the TypeScript compilation fixes from PR #92 into a single, clean pull request.

Context

• PR Add PostgreSQL service integration test workflow with database lifecycle management #91 added PostgreSQL integration test infrastructure but has TypeScript compilation errors
• PR Fix TypeScript compilation errors in database client #92 fixed those TypeScript errors but is stacked on top of PR Add PostgreSQL service integration test workflow with database lifecycle management #91
• Need to merge both sets of changes into one cohesive PR targeting main

Changes to Include

1. Integration Test Infrastructure (from PR #91)

New Files:

• .github/workflows/integration-tests.yml - PostgreSQL service workflow
• jest.integration.setup.ts - Database initialization before tests
• jest.integration.teardown.ts - Database cleanup after tests
• src/database/test-seeder.ts - Test data seeding utilities

Modified Files:

• jest.integration.config.js - Must reference the new setup/teardown files:

module.exports = {
  preset: 'ts-jest',
  testEnvironment: 'node',
  roots: ['<rootDir>/src'],
  testMatch: ['**/__tests__/integration/**/*.ts'],
  globalSetup: '<rootDir>/jest.integration.setup.ts',
  globalTeardown: '<rootDir>/jest.integration.teardown.ts',
  setupFilesAfterEnv: ['<rootDir>/jest.setup.ts'],
  collectCoverageFrom: [
    'src/**/*.ts',
    '!src/**/*.d.ts',
    '!src/**/*.test.ts',
    '!src/**/__tests__/**'
  ],
  transformIgnorePatterns: [
    'node_modules/(?!(uuid)/)'
  ],
  testTimeout: 30000
};

• package.json - Ensure scripts and dependencies are correct including @types/node in devDependencies

2. TypeScript Compilation Fixes (from PR #92)

File: src/database/client.ts

Apply these fixes:

1. Use type-only import: import type { QueryResult } from 'pg';
2. Properly typed error handler: this.pool.on('error', (err: Error) => { ... })
3. Merge config properly: this.pool = new Pool({ ...defaultConfig, ...config });

The corrected constructor should be:

constructor(config?: PoolConfig) {
  const defaultConfig: PoolConfig = {
    host: process.env.DATABASE_HOST || 'localhost',
    port: parseInt(process.env.DATABASE_PORT || '5432'),
    database: process.env.DATABASE_NAME || 'vexel',
    user: process.env.DATABASE_USER || 'vexel_user',
    password: process.env.DATABASE_PASSWORD || '',
    max: 20,
    idleTimeoutMillis: 30000,
    connectionTimeoutMillis: 2000,
  };

  this.pool = new Pool({ ...defaultConfig, ...config });

  // Handle pool errors
  this.pool.on('error', (err: Error) => {
    console.error('Unexpected database error:', err);
  });
}

File: package.json
Ensure @types/node is in devDependencies (should already be at version ^25.0.9)

3. Integration Test Example

File: src/database/__tests__/integration/database-client.integration.test.ts

Create a basic integration test to verify the setup works:

/**
 * Database Client Integration Tests
 * Tests real database operations with PostgreSQL
 */

import { DatabaseClient } from '../../client';
import { TestDataSeeder } from '../../test-seeder';
import { RuntimeStatus } from '../../../types';

describe('DatabaseClient Integration Tests', () => {
  let db: DatabaseClient;
  let seeder: TestDataSeeder;

  beforeAll(() => {
    db = new DatabaseClient();
    seeder = new TestDataSeeder(db);
  });

  afterAll(async () => {
    await db.close();
  });

  beforeEach(async () => {
    await seeder.cleanAll();
  });

  describe('Connection', () => {
    it('should connect to the database', async () => {
      const isConnected = await db.testConnection();
      expect(isConnected).toBe(true);
    });

    it('should execute a simple query', async () => {
      const result = await db.query('SELECT NOW() as current_time');
      expect(result.rows).toHaveLength(1);
      expect(result.rows[0].current_time).toBeDefined();
    });
  });

  describe('Agent Operations', () => {
    it('should create and retrieve an agent', async () => {
      const agent = await seeder.createTestAgent({
        name: 'Integration Test Agent',
        did: 'did:vexel:integration:test-001'
      });

      expect(agent).toBeDefined();
      expect(agent.name).toBe('Integration Test Agent');
      expect(agent.runtime_status).toBe(RuntimeStatus.ACTIVE);
    });

    it('should clean up test data', async () => {
      await seeder.createTestAgent();
      let count = await seeder.getAgentCount();
      expect(count).toBe(1);

      await seeder.cleanAll();
      count = await seeder.getAgentCount();
      expect(count).toBe(0);
    });
  });

  describe('Transactions', () => {
    it('should commit a successful transaction', async () => {
      await db.transaction(async (client) => {
        await client.query(
          'INSERT INTO agents (did, name, owner_address, runtime_status) VALUES ($1, $2, $3, $4)',
          ['did:vexel:tx:test-001', 'Transaction Test', '0x1234567890123456789012345678901234567890', RuntimeStatus.ACTIVE]
        );
      });

      const count = await seeder.getAgentCount();
      expect(count).toBe(1);...
