# DCRouter SMTP Test Suite
This comprehensive test suite validates the production readiness of the dcrouter SMTP implementation. All tests are built using TypeScript with tstest/tapbundle/smartexpect for consistent test patterns across the codebase.
## 📊 Test Status Legend
**Test Result Status**:
| Status | Symbol | Meaning | Description |
|--------|--------|---------|-------------|
| **✅ PASSED** | ✅ | Test executed and passed | Test ran successfully and all assertions passed |
| **❌ FAILED** | ❌ | Test executed but failed | Test ran but assertions failed or errors occurred |
| **⚠️ TIMEOUT** | ⚠️ | Test execution timed out | Test exceeded maximum execution time limit |
| **🔧 VALIDATION** | 🔧 | Expected validation passed | Test confirmed proper error handling/validation works |
## 📈 Production Readiness Levels
| Level | Symbol | Criteria | Description |
|-------|--------|----------|-------------|
| **🟢 PRODUCTION READY** | 🟢 | ≥80% success rate | Component validated for production deployment |
| **🟡 NEAR READY** | 🟡 | 60-79% success rate | Component needs minor fixes before production |
| **🟠 DEVELOPMENT** | 🟠 | 40-59% success rate | Component in active development, not production ready |
| **🔴 NOT READY** | 🔴 | <40% success rate | Component requires significant work before production |
## Test Organization
Tests are organized into logical categories within the `suite/` directory:

## Client Performance Benchmarks
## Test Infrastructure
Expected performance metrics for production-ready SMTP client:
- **Sending Rate**: >100 emails per second (with connection pooling)
- **Connection Pool Size**: 10-50 concurrent connections efficiently managed
- **Memory Usage**: <500MB for 1000 concurrent email operations
- **DNS Cache Hit Rate**: >90% for repeated domains
- **Retry Success Rate**: >95% for temporary failures
- **Large Attachment Support**: Files up to 25MB without performance degradation
- **Queue Processing**: >1000 emails/minute with persistent queue
### Server Loader Module
## Client Security Requirements
All test files import the server loader module which provides:
- Automatic SMTP server lifecycle management
- Server starts before test execution
- Server stops after test completion
- Port allocation and cleanup
- Resource tracking and cleanup
All client security tests must pass for production deployment:
- **TLS Support**: TLS 1.2+ required, TLS 1.3 preferred
- **Authentication**: Support for LOGIN, PLAIN, CRAM-MD5, OAuth2
- **Certificate Validation**: Proper certificate chain validation
- **DKIM Signing**: Automatic DKIM signature generation
- **Credential Security**: No plaintext password storage
- **Injection Prevention**: Protection against header/command injection
Example test structure:
```typescript
import { tap, expect } from '@git.zone/tstest/tapbundle';
import { startTestServer, stopTestServer } from '../../helpers/server.loader.js';
## Client Production Readiness Criteria
let testServer: any;
### Production Gate 1: Core Functionality (>95% tests passing)
- Basic connection establishment
- Command execution and response parsing
- Email composition and sending
- Error handling and recovery
tap.test('setup - start SMTP server', async () => {
testServer = await startTestServer({
port: 2525,
tlsEnabled: true
});
expect(testServer).toBeInstanceOf(Object);
});
### Production Gate 2: Advanced Features (>90% tests passing)
- Connection pooling and reuse
- Authentication mechanisms
- TLS/STARTTLS support
- Retry logic and resilience
// Your tests here...
### Production Gate 3: Enterprise Ready (>85% tests passing)
- High-volume sending capabilities
- Advanced security features
- Full RFC compliance
- Performance under load
tap.test('cleanup - stop SMTP server', async () => {
await stopTestServer(testServer);
});
## Key Differences: Server vs Client Tests
tap.start();
```
| Aspect | Server Tests | Client Tests |
|--------|--------------|--------------|
| **Focus** | Accepting connections, processing commands | Making connections, sending commands |
| **Security** | Validating incoming data, enforcing policies | Protecting credentials, validating servers |
| **Performance** | Handling many clients concurrently | Efficient bulk sending, connection reuse |
| **Reliability** | Staying up under attack/load | Retrying failures, handling timeouts |
| **RFC Compliance** | Server MUST requirements | Client MUST requirements |
