System Testing

This document details the system testing practices in Anya.

Test Types

1. End-to-End Tests

#[tokio::test]
async fn test_complete_transaction_flow() {
    // Initialize complete system
    let system = TestSystem::new()
        .with_all_components()
        .build()
        .await?;

    // Create and fund wallet
    let wallet = system.create_wallet().await?;
    system.fund_wallet(&wallet, "1.0").await?;

    // Create and broadcast transaction
    let tx = wallet.create_transaction("0.1", "recipient").await?;
    let result = system.broadcast_and_confirm_transaction(tx).await?;

    // Verify system state
    assert!(result.is_confirmed());
    assert_eq!(wallet.get_balance().await?, "0.9");

    system.cleanup().await;
}

2. Load Tests

#[tokio::test]
async fn test_system_under_load() {
    let system = TestSystem::new()
        .with_monitoring()
        .build()
        .await?;

    // Generate load
    let load_generator = LoadGenerator::new()
        .transactions_per_second(100)
        .duration(Duration::from_secs(300))
        .build();

    // Run load test
    let metrics = system.run_load_test(load_generator).await?;

    // Verify system performance
    assert!(metrics.average_response_time < Duration::from_millis(100));
    assert!(metrics.error_rate < 0.001);
    assert!(metrics.throughput > 95.0);

    system.cleanup().await;
}

3. Recovery Tests

#[tokio::test]
async fn test_system_recovery() {
    let system = TestSystem::new()
        .with_fault_injection()
        .build()
        .await?;

    // Inject faults
    system.inject_network_partition().await;
    system.inject_node_failure(NodeId::new(1)).await;
    system.inject_database_corruption().await;

    // Verify system continues functioning
    let tx = system.create_test_transaction().await?;
    assert!(system.can_process_transaction(&tx).await?);

    // Test recovery
    system.recover().await?;
    assert!(system.is_fully_operational().await?);

    system.cleanup().await;
}

Test Implementation

1. System Setup

pub struct SystemTestContext {
    network: Network,
    wallets: Vec<Wallet>,
    database: Database,
    monitoring: Monitoring,
}

impl SystemTestContext {
    pub async fn setup() -> Self {
        // Initialize components
        let network = Network::new_test_network().await?;
        let wallets = create_test_wallets(5).await?;
        let database = Database::new_test_database().await?;
        let monitoring = Monitoring::new().await?;

        Self {
            network,
            wallets,
            database,
            monitoring,
        }
    }

    pub async fn teardown(self) {
        // Cleanup in reverse order
        self.monitoring.shutdown().await?;
        self.database.cleanup().await?;
        for wallet in self.wallets {
            wallet.cleanup().await?;
        }
        self.network.shutdown().await?;
    }
}

2. Test Scenarios

#[tokio::test]
async fn test_system_scenarios() {
    let ctx = SystemTestContext::setup().await;

    // Test normal operation
    test_normal_operation(&ctx).await?;

    // Test error conditions
    test_error_conditions(&ctx).await?;

    // Test performance
    test_performance_scenarios(&ctx).await?;

    ctx.teardown().await;
}

async fn test_normal_operation(ctx: &SystemTestContext) -> Result<()> {
    // Implementation of normal operation tests
    Ok(())
}

async fn test_error_conditions(ctx: &SystemTestContext) -> Result<()> {
    // Implementation of error condition tests
    Ok(())
}

async fn test_performance_scenarios(ctx: &SystemTestContext) -> Result<()> {
    // Implementation of performance tests
    Ok(())
}

3. Monitoring and Metrics

pub struct SystemMetrics {
    response_times: Vec<Duration>,
    error_counts: HashMap<ErrorType, usize>,
    throughput: f64,
}

impl SystemMetrics {
    pub fn average_response_time(&self) -> Duration {
        // Calculate average response time
        Duration::from_secs_f64(
            self.response_times.iter()
                .map(|d| d.as_secs_f64())
                .sum::<f64>() / self.response_times.len() as f64
        )
    }

    pub fn error_rate(&self) -> f64 {
        // Calculate error rate
        let total_errors: usize = self.error_counts.values().sum();
        let total_operations = self.response_times.len();
        total_errors as f64 / total_operations as f64
    }
}

Best Practices

  • Resource cleanup

2. Test Implementation

  • Comprehensive scenarios
  • Error simulation
  • Performance monitoring
  • State verification

3. Test Maintenance

  • Regular updates
