Writing Integration Tests

What testing consideration is being addressed with TEST_TIMEOUT?

describe('Database integration', () => {
  const TEST_TIMEOUT = 10000;
  
  beforeEach(async () => {
    await resetDatabase();
  }, TEST_TIMEOUT);
  
  test('should handle concurrent operations', async () => {
    const operations = Array(10).fill().map(() =>
      createUser({ name: 'Test User' })
    );
    
    const results = await Promise.all(operations);
    const dbUsers = await findAllUsers();
    
    expect(dbUsers.length).toBe(operations.length);
  }, TEST_TIMEOUT);
});

Handling slow operations
This addresses handling slow operations in tests: 1) Sets a longer timeout for database operations, 2) Prevents false test failures due to slow operations, 3) Accounts for database cleanup and setup time, 4) Necessary for testing concurrent operations, 5) Common requirement for integration tests with real databases, 6) Helps prevent flaky tests due to timing issues, 7) Important for CI/CD pipeline stability, 8) Balances test reliability with execution time.
