Test Suite

This project uses Node.js built-in test runner (requires Node 18+). No external testing dependencies required.

Running Tests

# Run all tests
npm test

# Run only unit tests
npm run test:unit

# Run only integration tests
npm run test:integration

# Run tests in watch mode (auto-rerun on file changes)
npm run test:watch

What We Test

Unit Tests

callback_queue.test.js

• Callback registration and invocation
• Multiple callbacks with arguments
• Error handling

host_lookup.test.js

• Host lookup tree algorithm
• Wildcard matching (single and double)
• Exact match priority
• Edge cases (no match, empty input, etc.)

unix_socket.test.js

• Unix socket server creation
• JSON message parsing
• Partial data buffering
• Multiple connections
• Error handling

Integration Tests

dns_provider.test.js

• DNS provider contract compliance
• All existing providers (Cloudflare, DigitalOcean, PorkBun, DuckDNS)
• Method signatures
• Key mapping
• Type validation

Adding a New DNS Provider

When you add a new DNS provider, you MUST add tests to ensure it meets the contract:

1. Create your provider class extending DnsApi in models/dns_provider/yourprovider.js

2. Add a test block in test/integration/dns_provider.test.js:

describe('YourProvider Provider', () => {
    const YourProvider = require('../../models/dns_provider/yourprovider');

    test('should meet DNS provider contract', () => {
        const mockCredentials = {api_key: 'mock-key'};
        const instance = validateDnsProviderContract(YourProvider, mockCredentials);
        assert.ok(instance, 'YourProvider should be instantiated');
    });

    test('should have correct _keyMap structure', () => {
        // Test your specific credential requirements
        assert.ok(YourProvider._keyMap.api_key);
        assert.strictEqual(YourProvider._keyMap.api_key.type, 'string');
        assert.strictEqual(YourProvider._keyMap.api_key.isRequired, true);
    });

    test('should have valid method signatures', () => {
        const instance = new YourProvider({api_key: 'mock'});
        validateMethodSignatures(instance);
    });

    test('should validate key mapping', () => {
        const instance = new YourProvider({api_key: 'mock'});
        validateKeyMapping(instance);
    });

    test('should validate type checking', () => {
        const instance = new YourProvider({api_key: 'mock'});
        validateTypeChecking(instance);
    });
});

3. Run tests to verify compliance:

npm run test:integration

DNS Provider Contract

All DNS providers must:

1. Extend DnsApi base class
2. Define static _keyMap with required credentials
3. Define static display properties: displayName, displayIconHtml, displayIconUni
4. Implement required methods:
   • listDomains() - Returns array of {domain, zoneId}
   • getRecords(domain, options) - Returns array of DNS records
   • createRecord(domain, options) - Creates a record
   • deleteRecords(domain, options) - Deletes matching records
5. Define __apiKeyMap to translate between class keys and API keys
6. Implement or inherit __typeCheck() for record type validation
7. Throw appropriate errors from this.errors object

CI/CD Integration

Tests can be run in GitHub Actions, GitLab CI, or any CI/CD system:

# Example GitHub Actions workflow
- name: Run tests
  run: npm test

Philosophy

We test custom logic, not third-party code:

• YES: Test our host lookup algorithm
• YES: Test our socket buffering logic
• YES: Test DNS provider contracts
• NO: Don't test Express.js routing
• NO: Don't test the Redis ORM
• NO: Don't test external DNS APIs (use mocks)

Notes

• Tests use Node's built-in node:test and node:assert modules
• No external testing framework needed
• Tests are fast and run in parallel by default
• Mock external services (Redis, DNS APIs) to avoid network calls
• Focus on testing business logic, not infrastructure
