🧪 Testing Strategy

Comprehensive testing approach for the BLGV Bitcoin-native ecosystem.

🎯 Testing Philosophy

Bitcoin-First Testing

• No Mock Data: All tests use regtest environment or real API responses
• Real-Time Testing: WebSocket connections and live data streams
• Security-First: Authentication, authorization, and Bitcoin operations
• Mobile-First: Primary testing on mobile devices and responsive layouts

🏗️ Test Pyramid

Unit Tests (70%)

// Treasury calculations
describe('Bitcoin-per-Share Calculations', () => {
  it('should calculate BPS correctly', () => {
    const btcHoldings = 6.39316479;
    const sharesOutstanding = 88100000;
    const bps = calculateBPS(btcHoldings, sharesOutstanding);
    expect(bps).toBeCloseTo(0.0000726);
  });
});

// API response validation
describe('Treasury API', () => {
  it('should return valid treasury data structure', async () => {
    const response = await getTreasuryData();
    expect(response).toMatchObject({
      btcHoldings: expect.any(Number),
      navPerShare: expect.any(Number),
      treasuryValue: expect.any(Number)
    });
  });
});

    const treasuryUpdate = await updateTreasuryFromDEX(dexFees);
    expect(treasuryUpdate.success).toBe(true);
  });
});

// Database operations
describe('Multi-Schema Database', () => {
  it('should operate across schemas correctly', async () => {
    const treasuryData = await db.treasury.getTreasuryMetrics();

E2E Tests (10%)

// Complete user workflows
describe('Mobile App E2E', () => {
  it('should complete treasury workflow', async () => {
    // Launch app
    await device.launchApp();
    
    // Authenticate
    await element(by.id('biometric-auth')).tap();
    await device.matchBiometric();
    
    // Navigate to treasury
    await element(by.text('Treasury')).tap();
    
    // Verify data display
    await expect(element(by.id('btc-holdings'))).toBeVisible();
    await expect(element(by.id('nav-per-share'))).toBeVisible();
  });
});

🧪 Test Environment Strategy

Regtest Environment

# Start full regtest ecosystem
cd regtest-ecosystem
./start-regtest.sh

# Run tests against regtest
npm test -- --env=regtest

Test Data Generation

// Regtest utilities
const createTestScenario = async () => {
  // Generate Bitcoin test data
  const testWallet = await regtestUtils.createWallet();
  const testTransaction = await regtestUtils.generateTransaction(testWallet);
  
  // Mine blocks
  await regtestUtils.mineBlocks(6);
  
  // Create treasury scenario
  await regtestUtils.simulateTreasuryPurchase(1.5); // 1.5 BTC
  
  return { testWallet, testTransaction };
};

📱 Mobile Testing Strategy

Device Testing Matrix

const testDevices = [
  { platform: 'iOS', version: '17.0', device: 'iPhone 15' },
  { platform: 'iOS', version: '16.0', device: 'iPhone 14' },
  { platform: 'Android', version: '14', device: 'Pixel 8' },
  { platform: 'Android', version: '13', device: 'Galaxy S23' }
];

// Cross-platform testing
testDevices.forEach(({ platform, version, device }) => {
  describe(`${platform} ${version} on ${device}`, () => {
    it('should authenticate with biometrics', async () => {
      await testBiometricAuth(platform);
    });
  });
});

Expo Testing

      if (data.type === 'treasury_update') {
        expect(data.payload.btcHoldings).toBeGreaterThan(0);
        done();
      }
    };
    
    // Trigger treasury update
    updateTreasuryHoldings();
  });

📝 Best Practices

1. Test Isolation: Each test should be independent
2. Real Data: Use regtest environment, not mocks
3. Security Focus: Test all authentication paths
4. Performance Monitoring: Track test execution times
5. Clear Naming: Tests should be self-documenting
6. Regular Updates: Keep tests current with features
7. Failure Analysis: Investigate all test failures
8. Documentation: Document complex test scenarios

Remember: Every test should validate that we're building the world's premier Bitcoin-native financial ecosystem correctly.
