Testing

This guide covers how to test your PocketDNS integration effectively.

Sandbox Environment

The PocketDNS sandbox environment provides a safe space to test your integration without affecting real domains or billing.

Sandbox Features

Test domains: Use .test TLD for testing
Simulated transactions: No real charges occur
Isolated data: Separate from production data
Full API compatibility: Same endpoints and responses as production

Sandbox URLs

API: https://api.sandbox.pocketdns.com
Embed: https://embed.sandbox.pocketdns.com
Dashboard: https://dashboard.sandbox.pocketdns.com

Test Domain Purchases

In sandbox, you can purchase test domains:

javascript

// Test domains are automatically available in sandbox
const testDomains = [
  'example1.test',
  'example2.test',
  'mysite.test'
];

// Purchase will succeed immediately without payment

Unit Testing

Testing API Calls

javascript

// __tests__/pocketdns.test.js
import { createUserSession } from '../src/services/pocketdns';

// Mock fetch for testing
global.fetch = jest.fn();

describe('PocketDNS API', () => {
  beforeEach(() => {
    fetch.mockClear();
  });

  test('creates user session successfully', async () => {
    const mockResponse = {
      user_identifier: 'test_user_123',
      login_url: 'https://embed.sandbox.pocketdns.com/session/abc123',
      expires_at: '2025-01-07T12:00:00Z'
    };

    fetch.mockResolvedValueOnce({
      ok: true,
      json: async () => mockResponse
    });

    const result = await createUserSession('test_user_123', '[email protected]');
    
    expect(result).toEqual(mockResponse);
    expect(fetch).toHaveBeenCalledWith(
      'https://api.sandbox.pocketdns.com/api/v1/users',
      expect.objectContaining({
        method: 'POST',
        headers: expect.objectContaining({
          'Authorization': expect.stringContaining('Bearer'),
          'Content-Type': 'application/json'
        })
      })
    );
  });

  test('handles API errors gracefully', async () => {
    fetch.mockResolvedValueOnce({
      ok: false,
      status: 401,
      statusText: 'Unauthorized'
    });

    await expect(
      createUserSession('invalid_user')
    ).rejects.toThrow('Failed to create session: Unauthorized');
  });
});

Testing React Components

javascript

// __tests__/PocketDNSEmbed.test.js
import React from 'react';
import { render, screen, waitFor } from '@testing-library/react';
import PocketDNSEmbed from '../src/components/PocketDNSEmbed';

// Mock the API service
jest.mock('../src/services/pocketdns', () => ({
  createUserSession: jest.fn()
}));

import { createUserSession } from '../src/services/pocketdns';

describe('PocketDNSEmbed', () => {
  test('shows loading state initially', () => {
    render(<PocketDNSEmbed userIdentifier="test_user" />);
    expect(screen.getByText('Loading domain interface...')).toBeInTheDocument();
  });

  test('renders iframe when session loads', async () => {
    createUserSession.mockResolvedValue({
      login_url: 'https://embed.sandbox.pocketdns.com/session/abc123'
    });

    render(<PocketDNSEmbed userIdentifier="test_user" />);

    await waitFor(() => {
      const iframe = screen.getByTitle('Domain Management');
      expect(iframe).toBeInTheDocument();
      expect(iframe.src).toBe('https://embed.sandbox.pocketdns.com/session/abc123');
    });
  });

  test('shows error state on API failure', async () => {
    createUserSession.mockRejectedValue(new Error('API Error'));

    render(<PocketDNSEmbed userIdentifier="test_user" />);

    await waitFor(() => {
      expect(screen.getByText('Error: API Error')).toBeInTheDocument();
    });
  });
});

Integration Testing

End-to-End Testing with Cypress

javascript

// cypress/integration/domain-purchase.spec.js
describe('Domain Purchase Flow', () => {
  beforeEach(() => {
    // Set up test user
    cy.request('POST', 'https://api.sandbox.pocketdns.com/api/v1/users', {
      user_identifier: 'cypress_test_user',
      email: '[email protected]'
    }).then((response) => {
      cy.window().then((win) => {
        win.testSession = response.body;
      });
    });
  });

  it('completes domain purchase flow', () => {
    cy.visit('/domains');
    
    // Load the embed
    cy.get('[data-testid="pocketdns-embed"]').should('be.visible');
    
    // Switch to iframe context
    cy.get('iframe').then(($iframe) => {
      const iframe = $iframe.contents();
      
      // Search for a domain
      cy.wrap(iframe.find('input[placeholder="Search for a domain"]'))
        .type('cypress-test.test{enter}');
      
      // Click purchase button
      cy.wrap(iframe.find('button[data-testid="purchase-button"]'))
        .click();
      
      // Complete purchase (in sandbox, this is instant)
      cy.wrap(iframe.find('button[data-testid="confirm-purchase"]'))
        .click();
      
      // Verify success message
      cy.wrap(iframe.find('[data-testid="purchase-success"]'))
        .should('contain', 'Domain purchased successfully');
    });
    
    // Verify domain appears in user's account
    cy.request({
      url: `https://api.sandbox.pocketdns.com/api/v1/users/cypress_test_user/domains`,
      headers: {
        'Authorization': `Bearer ${Cypress.env('POCKETDNS_SANDBOX_API_KEY')}`
      }
    }).then((response) => {
      expect(response.body.domains).to.have.length.greaterThan(0);
      expect(response.body.domains[0].name).to.equal('cypress-test.test');
    });
  });
});

Testing Webhooks

javascript

// __tests__/webhooks.test.js
import request from 'supertest';
import app from '../src/app';

describe('PocketDNS Webhooks', () => {
  test('handles domain purchase webhook', async () => {
    const webhookPayload = {
      event: 'domain.purchased',
      data: {
        domain_id: 'dom_123456',
        user_identifier: 'test_user_123',
        domain_name: 'example.test',
        purchased_at: '2025-01-06T12:00:00Z'
      }
    };

    const response = await request(app)
      .post('/webhooks/pocketdns')
      .send(webhookPayload)
      .expect(200);

    expect(response.body.success).toBe(true);
    
    // Verify that DNS records were created
    // Verify user notification was sent
    // etc.
  });
});

Performance Testing

API Response Time Testing

javascript

// __tests__/performance.test.js
import { createUserSession, getUserDomains } from '../src/services/pocketdns';

describe('PocketDNS Performance', () => {
  test('user session creation completes within 2 seconds', async () => {
    const start = Date.now();
    
    await createUserSession('perf_test_user', '[email protected]');
    
    const duration = Date.now() - start;
    expect(duration).toBeLessThan(2000);
  });

  test('domain fetching handles large datasets', async () => {
    // Test with user that has many domains
    const start = Date.now();
    
    const domains = await getUserDomains('user_with_many_domains');
    
    const duration = Date.now() - start;
    expect(domains.length).toBeGreaterThan(0);
    expect(duration).toBeLessThan(5000);
  });
});

            user_identifier: 'load_test_{{ $randomString() }}'
            email: 'test{{ $randomInt(1, 1000) }}@example.com'
          capture:
            - json: '$.user_identifier'
              as: 'userId'
      - get:
          url: '/api/v1/users/{{ userId }}/domains'

Monitoring and Debugging

Test Data Cleanup

javascript

// scripts/cleanup-test-data.js
const cleanupTestData = async () => {
  const testUsers = await getUsersWithPrefix('test_');
  
  for (const user of testUsers) {
    const domains = await getUserDomains(user.user_identifier);
    
    for (const domain of domains) {
      if (domain.name.endsWith('.test')) {
        await deleteDomain(domain.id);
      }
    }
    
    await deleteUser(user.user_identifier);
  }
  
  console.log(`Cleaned up ${testUsers.length} test users`);
};

Debug Logging

javascript

// utils/debug.js
const debug = require('debug');

const pocketDNSDebug = debug('app:pocketdns');

export const logAPICall = (method, url, data) => {
  pocketDNSDebug(`${method} ${url}`, data);
};

export const logAPIResponse = (response) => {
  pocketDNSDebug('Response:', response.status, response.data);
};

Best Practices

Always test in sandbox first before production deployment
Use test data that's easy to identify and clean up
Test error scenarios as thoroughly as success scenarios
Monitor API response times and set performance budgets
Clean up test data regularly to avoid clutter
Test across different browsers and devices
Validate all user inputs before sending to API
Test webhook delivery and handling
Use proper test isolation to avoid test interference
Keep test credentials separate from production credentials
