# Testing Guide

Comprehensive testing strategy for Ring Platform with unit tests, integration tests, and end-to-end testing.

## 🧪 Testing Strategy

### Testing Pyramid
Ring Platform follows the testing pyramid approach:

1. **Unit Tests** (70%) - Individual functions and components
2. **Integration Tests** (20%) - Component interactions and API endpoints
3. **End-to-End Tests** (10%) - Complete user workflows

## ⚡ Unit Testing

### Jest Configuration
// jest.config.js

{`module.exports = {
  testEnvironment: 'jsdom',
  setupFilesAfterEnv: ['/jest.setup.js'],
  testMatch: ['**/__tests__/**/*.test.{js,ts,tsx}'],
  collectCoverageFrom: [
    'src/**/*.{js,ts,tsx}',
    '!src/**/*.d.ts'
  ]
}`}

### Component Testing Example
// __tests__/components/EntityCard.test.tsx

{`import { render, screen } from '@testing-library/react'
import { EntityCard } from '@/components/EntityCard'

describe('EntityCard', () => {
  it('renders entity information correctly', () => {
    const entity = {
      id: '1',
      name: 'Test Company',
      type: 'technology'
    }

    render()
    
    expect(screen.getByText('Test Company')).toBeInTheDocument()
    expect(screen.getByText('technology')).toBeInTheDocument()
  })
})`}

## 🔗 Integration Testing

### API Route Testing
// __tests__/api/entities.test.ts

{`import { POST } from '@/app/api/entities/route'
import { NextRequest } from 'next/server'

describe('/api/entities', () => {
  it('creates entity successfully', async () => {
    const request = new NextRequest('http://localhost:3000/api/entities', {
      method: 'POST',
      body: JSON.stringify({
        name: 'Test Entity',
        type: 'technology'
      })
    })

    const response = await POST(request)
    const data = await response.json()

    expect(response.status).toBe(201)
    expect(data.entity.name).toBe('Test Entity')
  })
})`}

## 🎭 End-to-End Testing

### Playwright Configuration
// playwright.config.ts

{`import { defineConfig } from '@playwright/test'

export default defineConfig({
  testDir: './e2e',
  use: {
    baseURL: 'http://localhost:3000',
    headless: true,
    screenshot: 'only-on-failure'
  },
  projects: [
    { name: 'chromium', use: { ...devices['Desktop Chrome'] } },
    { name: 'firefox', use: { ...devices['Desktop Firefox'] } }
  ]
})`}

### E2E Test Example
// e2e/authentication.spec.ts

{`import { test, expect } from '@playwright/test'

test('user can sign in with Google', async ({ page }) => {
  await page.goto('/')
  await page.click('text=Sign In')
  
  // Mock Google OAuth response
  await page.route('**/api/auth/**', route => {
    route.fulfill({
      status: 200,
      body: JSON.stringify({ user: { name: 'Test User' } })
    })
  })
  
  await page.click('text=Sign in with Google')
  await expect(page.locator('text=Welcome, Test User')).toBeVisible()
})`}

## 📊 Test Coverage

### Coverage Requirements
- **Overall**: > 80% line coverage
- **Critical paths**: > 95% coverage
- **New features**: 100% coverage required

### Running Tests
Unit tests Watch mode during development Coverage report E2E tests

{`npm run test

npm run test:watch

npm run test:coverage

npm run test:e2e`}
