// Since we can't easily mock the full NestJS infrastructure,
// this test script demonstrates the expected usage patterns.

console.log('\n🧪 To run actual tests:');
console.log('1. Start the NestJS application: npm run start:dev');
console.log('2. Use the FarcasterService in a controller or service');
console.log('3. Test with real Farcaster usernames');

console.log('\n📋 Example Usage:');
console.log(`
// In a NestJS service or controller:
const casts = await this.farcasterService.getRecentCasts('dwr.eth');
console.log(\`Found \${casts.length} casts\`);

// Incremental fetching:
const timestamp = new Date('2024-01-01');
const newCasts = await this.farcasterService.getRecentCastsIncremental('vitalik.eth', timestamp);

// Validation:
const isValid = this.farcasterService.isValidFarcasterUsername('user.eth');
