Testing

This library includes comprehensive tests for all adapters using real API credentials. Tests are designed to work with actual services to ensure reliability.

Test Configuration

1. Copy the example environment file:

   cp .env.example .env

2. Configure your credentials in .env:

   # Example for Mailgun
   MAILGUN_API_KEY=key-1234567890abcdef
   MAILGUN_DOMAIN=mg.yourdomain.com
   MAILGUN_IS_EU=false
   
   # Example for Twilio
   TWILIO_ACCOUNT_SID=AC1234567890abcdef
   TWILIO_AUTH_TOKEN=your_auth_token
   TWILIO_FROM=+1234567890
   
   # Add other service credentials as needed

3. Alternatively, configure credentials in test.config.ts:

   export const testConfig: TestConfig = {
     mailgun: {
       apiKey: "your-actual-api-key",
       domain: "your-domain.com",
       isEU: false,
       testEmail: "[email protected]",
     },
     // ... other configurations
   };

Running Tests

# Run all tests
bun test

# Run tests with coverage
bun test --coverage

# Run tests in watch mode
bun test --watch

# Run specific test files
bun test tests/adapters/email.test.ts
bun test tests/adapters/sms.test.ts
bun test tests/adapters/push.test.ts

Test Behavior

• Configured Services: Tests will run with real API calls for services with valid credentials
• Unconfigured Services: Tests will be automatically skipped with helpful messages
• Real API Calls: Tests use actual service APIs to ensure reliability
• Test Messages: All test messages are clearly marked and include unique identifiers

Example Test Output

🧪 Starting Nuvix Messaging Adapter Tests
📊 Test Configuration Summary:
✅ Configured services: mailgun, twilio, fcm
⚠️  Unconfigured services (will be skipped): sendgrid, vonage, msg91, telesign, textmagic, apns
💡 To test these services, configure credentials in test.config.ts or environment variables

✅ Mailgun text email sent successfully
✅ Twilio SMS sent successfully
✅ FCM push notification sent successfully
⏭️  Skipping SendGrid tests: credentials not configured

Usage Examples

Email

import { Mailgun } from "@nuvix/messaging/adapter/Email/Mailgun";
import { Email } from "@nuvix/messaging/messages/Email";

const adapter = new Mailgun("api-key", "domain.com");
const email = new Email({
  to: ["[email protected]"],
  subject: "Hello World",
  content: "This is a test email",
  fromName: "Your App",
  fromEmail: "[email protected]",
});

const result = await adapter.send(email);
console.log(`Delivered to ${result.deliveredTo} recipients`);

SMS

import { Twilio } from "@nuvix/messaging/adapter/SMS/Twilio";
import { SMS } from "@nuvix/messaging/messages/SMS";

const adapter = new Twilio("account-sid", "auth-token", "+1234567890");
const sms = new SMS({
  to: ["+1987654321"],
  content: "Hello from your app!",
});

const result = await adapter.send(sms);

Push Notifications

import { FCM } from "@nuvix/messaging/adapter/Push/FCM";
import { Push } from "@nuvix/messaging/messages/Push";

const adapter = new FCM("service-account-json");
const push = new Push({
  to: ["device-token"],
  title: "New Message",
  body: "You have a new notification",
  data: { type: "message", id: "123" },
});

const result = await adapter.send(push);
