# Integration Testing

This document details the integration testing practices in Anya.

## Test Structure

### 1. Test Setup
```rust
// tests/integration_tests.rs
use anya::{Wallet, Network, Transaction};

// Test context
struct IntegrationTestContext {
    wallet: Wallet,
    network: Network,
}

impl IntegrationTestContext {
    async fn setup() -> Self {
        let wallet = Wallet::new_test_wallet().await;
        let network = Network::new_test_network().await;
        Self { wallet, network }
    }

    async fn teardown(self) {
        self.wallet.cleanup().await;
        self.network.cleanup().await;
    }
}
```

### 2. Component Integration
```rust
#[tokio::test]
async fn test_wallet_network_integration() {
    let ctx = IntegrationTestContext::setup().await;
    
    // Test wallet-network interaction
    let tx = ctx.wallet.create_transaction().await?;
    ctx.network.broadcast_transaction(&tx).await?;
    
    // Verify integration
    assert!(ctx.network.verify_transaction(&tx).await?);
    
    ctx.teardown().await;
}
```

### 3. System Integration
```rust
#[tokio::test]
async fn test_full_system_integration() {
    // Initialize system components
    let system = TestSystem::new()
        .with_wallet()
        .with_network()
        .with_database()
        .build()
        .await?;

    // Run integration flow
    let result = system.run_integration_flow().await?;
    
    // Verify system state
    assert!(system.verify_state().await?);
    
    system.cleanup().await;
}
```

## Test Scenarios

### 1. Component Interaction
```rust
#[tokio::test]
async fn test_component_interactions() {
    let ctx = IntegrationTestContext::setup().await;
    
    // Test wallet-to-network
    test_wallet_network_communication(&ctx).await?;
    
    // Test network-to-database
    test_network_database_sync(&ctx).await?;
    
    // Test database-to-wallet
    test_database_wallet_updates(&ctx).await?;
    
    ctx.teardown().await;
}
```

### 2. Data Flow
```rust
#[tokio::test]
async fn test_data_flow() {
    let ctx = IntegrationTestContext::setup().await;
    
    // Create test data
    let data = TestData::new();
    
    // Test data flow through system
    ctx.wallet.process_data(&data).await?;
    ctx.network.verify_data(&data).await?;
    ctx.database.store_data(&data).await?;
    
    ctx.teardown().await;
}
```

### 3. Error Handling
```rust
#[tokio::test]
async fn test_error_handling() {
    let ctx = IntegrationTestContext::setup().await;
    
    // Test network failure handling
    ctx.network.simulate_failure().await;
    let result = ctx.wallet.send_transaction().await;
    assert!(result.is_err());
    
    // Test recovery
    ctx.network.restore().await;
    let result = ctx.wallet.send_transaction().await;
    assert!(result.is_ok());
    
    ctx.teardown().await;
}
```

## Best Practices

### 1. Test Environment
- Isolated testing
- Clean state
- Resource management
- Configuration control

### 2. Test Implementation
- Comprehensive scenarios
- Error handling
- Performance monitoring
- State verification

### 3. Test Maintenance
- Regular updates
- Documentation
- CI/CD integration
- Monitoring and alerts
