🧭 AI-Aware Testing and Consistency Strategy

Overview

This document outlines the comprehensive testing and consistency strategy for the CapOpt Platform, ensuring reliable, schema-aligned, and testable development using Prisma, PostgreSQL, and Cursor as an AI pair.

🎯 Objectives

✅ Selector alignment across components, tests, and seeds
✅ Schema-aware generation of UI, logic, and test code
✅ Reliable test coverage across unit, integration, and E2E layers
✅ False validation avoidance, especially with AI-assisted code
✅ CI pipeline compatibility using consistent test data and ERD-informed artefacts

🏗️ Architecture

Test Layers

Layer	Toolset	Target	Coverage
Unit	Jest + @testing-library/react	Components, pure logic, hooks	70%
Integration	Jest + Prisma + seeded DB	Pages, API handlers, DB I/O	20%
API Route	node-mocks-http + supertest	`/app/api/*`	5%
E2E	Playwright	Full stack + UI interaction	5%
Schema	ERD + PlantUML + Markdown Docs	Authoritative structure reference	-

 * @note Demonstrates AI-aware testing strategy
 */

import { render, screen } from '@testing-library/react';
import userEvent from '@testing-library/user-event';
import { entityTestIds } from '@/lib/testSelectors';

describe('ComponentName', () => {
  const mockData = global.testUtils.createMockEntity();
  
  it('should render with valid test IDs', () => {
    render(<Component data={mockData} />);
    
    expect(screen.getByTestId(entityTestIds.componentContainer)).toBeInTheDocument();

      'GET', 
      '/api/entity?include=relation1,relation2&enterpriseId=test-enterprise'
    );
    const res = createMockResponse();
    
    await GET(req, res);
    
    expect(prisma.entity.findMany).toHaveBeenCalledWith({
      where: { enterpriseId: 'test-enterprise' },
      include: { relation1: true, relation2: true },
      orderBy: expect.any(Array)
    });
  });
  
  it('should validate complex metadata fields', async () => {

📚 Best Practices

Test ID Management

// ✅ CORRECT - Import from centralized file
import { entityTestIds } from '@/lib/testSelectors';

<div data-testid={entityTestIds.container}>
  <input data-testid={entityTestIds.inputField} />
</div>

// ❌ INCORRECT - Hardcoded test IDs
<div data-testid="test-container">
  <input data-testid="test-input" />
</div>

Mock Data Creation

// ✅ CORRECT - Use test utilities
const mockEntity = global.testUtils.createMockEntity({
  name: 'Custom Name',
  status: 'ACTIVE'
});

// ❌ INCORRECT - Manual mock data
const mockEntity = {
  id: 'test-id',
  name: 'Test Entity',
  // ... missing required fields
};

Schema-Aware Testing

// ✅ CORRECT - Validate against schema
const validation = global.testUtils.validateComplexForm(formData, entitySchema);
expect(validation.valid).toBe(true);

// ✅ CORRECT - Test Australian business data
expect(mockEntity).toBeAustralianBusinessData();

Error Handling

// ✅ CORRECT - Test error scenarios
it('should handle validation errors', async () => {
  const invalidData = { name: '', status: 'INVALID' };
  const req = createMockRequest('POST', '/api/entity', invalidData);
  const res = createMockResponse();
  
  await POST(req, res);
  
  expect(res.status).toHaveBeenCalledWith(400);
  expect(res.json).toHaveBeenCalledWith(
    expect.objectContaining({ error: 'Validation failed' })
  );
});

🔧 Troubleshooting

Common Issues

Test ID Validation Failures

# Check for invalid test IDs
npm run lint:test-ids

# Common fixes:
# 1. Import test IDs from lib/testSelectors.ts
# 2. Use correct test ID constants
# 3. Update testSelectors.ts if new IDs are needed

Schema Validation Errors

# Validate schema alignment
npm run validate:schema

# Common fixes:
# 1. Update schema documentation
# 2. Align test data with schema
# 3. Update validation schemas

Test Coverage Issues

# Generate coverage report
npm run test:coverage

# Common fixes:
# 1. Add missing test cases
# 2. Test error scenarios
# 3. Test edge cases

Performance Optimization

// Optimize test performance
describe('Performance Tests', () => {
  it('should handle large datasets efficiently', () => {
    const largeDataset = global.testUtils.createMultipleEntities(1000);
    expect(largeDataset).toHaveLength(1000);
  });
  
  it('should handle complex hierarchies efficiently', () => {
    const hierarchy = global.testUtils.createEntityHierarchy(5, 3);
    expect(hierarchy).toBeDefined();
  });
});
