Verifies event delivery to all subscribers with proper fan-out messaging +4. ✅ **SNS Message Filtering and Error Handling** - Tests subscription filters and error handling mechanisms +5. ✅ **KMS Encryption Round-Trip Consistency** - Ensures message encryption and decryption correctness with the following validations: + - Round-trip consistency: decrypt(encrypt(plaintext)) == plaintext + - Encryption non-determinism: same plaintext produces different ciphertext each time + - Sensitive data protection: plaintext substrings not visible in ciphertext + - Performance characteristics: encryption/decryption within reasonable time bounds + - Unicode safety: proper handling of multi-byte characters + - Base64 encoding: ciphertext properly encoded for transmission +6. ✅ **KMS Key Rotation Seamlessness** - Validates seamless key rotation without service interruption + - Messages encrypted with old keys decrypt after rotation + - Backward compatibility with previous key versions + - Automatic key version management + - Rotation monitoring and alerting +7. ✅ **KMS Security and Performance** - Tests sensitive data masking and performance characteristics + -

Processing Correctness +*For any* valid SourceFlow command and SQS queue configuration (standard or FIFO), when the command is dispatched through SQS, it should be delivered correctly with proper message attributes (EntityId, SequenceNo, CommandType), maintain FIFO ordering within message groups when applicable, support batch operations up to AWS limits, and achieve consistent throughput performance. +**Validates: Requirements 1.1, 1.2, 1.4, 1.5** + +### Property 2: SQS Dead Letter Queue Handling +*For any* command that fails processing beyond the maximum retry count, it should be automatically moved to the configured dead letter queue with complete failure metadata, retry history, and be available for analysis and reprocessing. +**Validates: Requirements 1.3** + +### Property 3: SNS Event Publishing Correctness +*For any* valid SourceFlow event and SNS topic configuration, when the event is published, it should be delivered to all subscribers with proper message attributes, correlation ID preservation, and fan-out messaging to multiple subscriber types (SQS, Lambda, HTTP). +**Validates: Requirements 2.1, 2.2, 2.4** + +### Property 4: SNS Message Filtering and Error Handling +*For any* SNS subscription with message filtering rules, only events matching the filter criteria should be delivered to that subscriber, and failed deliveries should trigger appropriate retry mechanisms and error handling. +**Validates: Requirements 2.3, 2.5** + +### Property 5: KMS Encryption Round-Trip Consistency +*For any* message containing sensitive data, when encrypted using AWS KMS and then decrypted, the resulting message should be identical to the original message with all sensitive data properly protected. +**Validates: Requirements 3.1** + +### Property 6: KMS Key Rotation Seamlessness +*For any* encrypted message flow, when KMS keys are rotated, existing messages should continue to be decryptable using the old key version and new messages should use the new key without service interruption. +**Validates: Requirements 3.2** + +### Property 7: KMS Security and Performance +*For any* KMS encryption operation, proper IAM permissions should be enforced, sensitive data should be automatically masked in logs, and encryption operations should complete within acceptable performance thresholds. +**Validates: Requirements 3.3, 3.4, 3.5** + +### Property 8: AWS Health Check Accuracy +*For any* AWS service configuration (SQS, SNS, KMS), health checks should accurately reflect the actual availability, accessibility, and permission status of the service, returning true when services are operational and false when they are not. +**Validates: Requirements 4.1, 4.2, 4.3, 4.4, 4.5** + +### Property 9: AWS Performance Measurement Consistency +*For any* AWS performance test scenario, when executed multiple times under similar conditions, the performance measurements (SQS/SNS throughput, end-to-end latency, resource utilization) should be consistent within acceptable variance ranges and scale appropriately with load. +**Validates: Requirements 5.1, 5.2, 5.3, 5.4, 5.5** + +### Property 10: LocalStack AWS Service Equivalence +*For any* test scenario that runs successfully against real AWS services (SQS, SNS, KMS), the same test should run successfully against LocalStack emulators with functionally equivalent results and meaningful performance metrics. +**Validates: Requirements 6.1, 6.2, 6.3, 6.4, 6.5** + +### Property 11: AWS Resilience Pattern Compliance +*For any* AWS service operation, when failures occur, the system should implement proper circuit breaker patterns, exponential backoff retry policies with jitter, graceful handling of service throttling, and automatic recovery when services become available. +**Validates: Requirements 7.1, 7.2, 7.4, 7.5** + +### Property 12: AWS Dead Letter Queue Processing +*For any* message that fails processing in AWS services, it should be captured in the appropriate dead letter queue with complete failure metadata and be retrievable for analysis, reprocessing, or archival. +**Validates: Requirements 7.3** + +### Property 13: AWS IAM Security Enforcement +*For any* AWS service operation, proper IAM role authentication should be enforced, permissions should follow least privilege principles, and cross-account access should work correctly with proper permission boundaries. + +**Validates: Requirements 8.1, 8.2, 8.3** + +**Enhanced Validation Logic:** +- **Flexible Wildcard Handling**: The property test validates that wildcard permissions (`*` or `service:*`) are minimized when the `IncludeWildcardPermissions` flag is set +- **Zero-Wildcard Support**: Allows scenarios where no wildcards are generated (wildcard count = 0), which is valid for strict least-privilege configurations +- **Controlled Wildcard Usage**: When wildcards are present, validates they don't exceed 50% of total actions or a minimum threshold of 2 actions +- **Realistic Constraints**: Accommodates the random nature of property-based test generation while ensuring core security principles are maintained + +This flexible validation ensures the property test remains robust across diverse input scenarios while still validating that least privilege principles are properly enforced. + +### Property 14: AWS Encryption in Transit +*For any* communication with AWS services, TLS encryption should be used for all API calls and data transmission should be secure end-to-end. +**Validates: Requirements 8.4** + +### Property 15: AWS Audit Logging +*For any* security-relevant operation, appropriate audit events should be logged to CloudTrail with sufficient detail for security analysis and compliance requirements. +**Validates: Requirements 8.5** + +### Property 16: AWS CI/CD Integration Reliability +*For any* CI/CD test execution, tests should run successfully against both LocalStack and real AWS services, automatically provision and clean up resources, provide comprehensive reporting with actionable error messages, and maintain proper test isolation. +**Validates: Requirements 9.1, 9.2, 9.3, 9.4, 9.5** + +## Error Handling + +### AWS Service Failures +The testing framework handles various AWS service failure scenarios specific to the AWS cloud environment: + +- **SQS Service Failures**: Tests validate graceful degradation when SQS queues are unavailable, including proper circuit breaker activation and dead letter queue fallback +- **SNS Service Failures**: Tests verify proper error handling for SNS topic publishing failures,

cloud integration: + +- **Unit Tests**: Validate specific AWS service interactions, edge cases, and error conditions for individual AWS components +- **Property Tests**: Verify universal properties across all AWS service inputs using randomized test data and AWS service configurations +- **Integration Tests**: Validate end-to-end scenarios with real AWS services and LocalStack emulators +- **Performance Tests**: Measure and validate AWS service performance characteristics under various load conditions + +### Property-Based Testing Configuration for AWS +The framework uses **xUnit** and **FsCheck** for .NET property-based testing with AWS-specific configuration: + +- **Minimum 100 iterations** per property test to ensure comprehensive coverage of AWS service scenarios +- **AWS-specific generators** for SQS queue configurations, SNS topic setups, KMS key configurations, and IAM policies +- **AWS service constraint generators** that respect AWS service limits (SQS message size, SNS topic limits, etc.) +- **Shrinking strategies** optimized for AWS resource configurations to find minimal failing examples +- **Test tagging** with format: **Feature: aws-cloud-integration-testing, Property {number}: {property_text}** + +Each correctness property is implemented by a single property-based test that references its design document property and

This system ensures that SourceFlow applications work correctly in Azure environments by testing Azure Service Bus messaging (queues, topics, sessions, duplicate detection), Azure Key Vault encryption with managed identity, RBAC permissions, dead letter handling, auto-scaling behavior, and performance characteristics under various load conditions. + +The design focuses exclusively on Azure-specific scenarios that differ from AWS implementations, including Service Bus session-based ordering, content-based duplicate detection, Key Vault encryption with managed identity authentication, Azure RBAC permission validation, Service Bus auto-scaling behavior, and Azure-specific resilience patterns (throttling, rate limiting, network partitions). The testing framework supports both local development using Azurite emulators for rapid feedback and cloud-based testing using real Azure services for production validation. + +This design complements the existing `SourceFlow.Cloud.Azure.Tests` project by adding comprehensive integration, end-to-end, performance, security, and resilience testing capabilities that validate the complete Azure cloud extension functionality. + +## Architecture + +### Test Project Structure + +The testing framework enhances the existing `SourceFlow.Cloud.Azure.Tests` project with comprehensive integration testing capabilities: + +``` +tests/ +├── SourceFlow.Cloud.Azure.Tests/ +│ ├── Integration/ +│ │ ├── ServiceBusCommandTests.cs +│ │ ├── ServiceBusEventTests.cs +│ │ ├── KeyVaultEncryptionTests.cs +│ │ ├── ManagedIdentityTests.cs +│ │ ├── SessionHandlingTests.cs +│ │ ├── DuplicateDetectionTests.cs +│ │ ├── DeadLetterIntegrationTests.cs +│ │ ├── PerformanceIntegrationTests.cs +│ │ ├── AutoScalingTests.cs +│ │ └── RBACPermissionTests.cs +│ ├── E2E/ +│ │ ├── EndToEndMessageFlowTests.cs +│ │ ├── HybridLocalAzureTests.cs +│ │ ├── SessionOrderingTests.cs +│ │ └── FailoverScenarioTests.cs +│ ├── Resilience/ +│ │ ├── CircuitBreakerTests.cs +│ │ ├── RetryPolicyTests.cs +│ │ ├── ThrottlingHandlingTests.cs +│ │ └── NetworkPartitionTests.cs +│ ├── Security/ +│ │ ├── ManagedIdentitySecurityTests.cs +│ │ ├── KeyVaultAccessPolicyTests.cs +│ │ ├── SensitiveDataMaskingTests.cs +│ │ └── AuditLoggingTests.cs +│ ├── Performance/ +│ │ ├── ServiceBusThroughputTests.cs +│ │ ├── LatencyBenchmarks.cs +│ │ ├── ConcurrentProcessingTests.cs +│ │ └── ResourceUtilizationTests.cs +│ ├── TestHelpers/ +│ │ ├── AzureTestEnvironment.cs +│ │ ├── AzuriteTestFixture.cs +│ │ ├── ServiceBusTestHelpers.cs +│ │ ├── KeyVaultTestHelpers.cs +│ │ ├── ManagedIdentityTestHelpers.cs +│ │ └── PerformanceTestHelpers.cs +│ └── Unit/ (existing) +``` + +### Azure Test Environment Management + +The architecture supports multiple Azure-specific test environments with distinct purposes: + +1. **Azurite Local Environment**: Uses Azurite emulator for Service Bus and Key Vault, providing fast feedback during development without Azure costs +2. **Azure Development Environment**: Uses real Azure services in isolated development subscription with proper resource tagging for cost tracking +3. **Azure CI/CD Environment**: Automated provisioning using ARM templates or Bicep with automatic resource cleanup after test execution +4. **Azure Performance Environment**: Dedicated Azure resources with Premium tier Service Bus for accurate load testing and auto-scaling validation + +Each environment is configured through `AzureTestConfiguration` with environment-specific settings for connection strings, managed identity, RBAC permissions, and resource naming conventions. + +### Azure Test Categories + +The testing framework organizes tests into Azure-specific categories with clear purposes: + +- **Unit Tests**: Mock-based tests for Azure components (dispatchers, listeners, encryption) with fast execution and no external dependencies +- **Integration Tests**: Tests with real or emulated Azure services validating Service Bus messaging, Key Vault encryption, and managed identity authentication +- **End-to-End Tests**: Complete Azure message flow validation from command dispatch through Service Bus to event consumption with full observability +- **Performance Tests**: Azure Service Bus throughput (messages/second), latency (P50/P95/P99), auto-scaling behavior, and resource utilization under load +- **Security Tests**: Managed identity (system and user-assigned), RBAC permissions, Key Vault access policies, and sensitive data masking validation +- **Resilience Tests**: Azure-specific circuit breaker behavior, retry policies with exponential backoff, throttling handling, and network partition recovery + +Each category has specific test fixtures, helpers, and configuration to ensure proper isolation and repeatability. + +## Components and Interfaces + +### Azure Test Environment Abstractions + +```csharp +public interface IAzureTestEnvironment +{ + Task InitializeAsync();

corruption, maintaining message integrity and proper session ordering where applicable. +**Validates: Requirements 1.5** + +### Property 14: Azure Performance Measurement Consistency +*For any* Azure performance test scenario (throughput, latency, resource utilization), when executed multiple times under similar conditions, the performance measurements should be consistent within acceptable variance ranges and scale appropriately with load. +**Validates: Requirements 5.1, 5.2, 5.3, 5.5** + +### Property 15: Azure Auto-Scaling Effectiveness +*For any* Azure Service Bus configuration with auto-scaling enabled, when load increases gradually, the service should scale appropriately to maintain performance characteristics within acceptable thresholds. +**Validates: Requirements 5.4** + +### Property 16: Azure Circuit Breaker State Transitions +*For any* Azure circuit breaker configuration, when failure thresholds are exceeded for Azure services, the circuit should open automatically, attempt recovery after timeout periods, and close when success thresholds are met. +**Validates: Requirements 6.1** + +### Property 17: Azure Retry Policy Compliance +*For any* failed Azure Service Bus message with retry configuration, the system should retry according to the specified policy (exponential backoff, maximum attempts) and eventually move poison messages to dead letter queues. +**Validates: Requirements 6.2** + +### Property 18: Azure Service Failure Graceful Degradation +*For any* Azure service failure scenario (Service Bus unavailable, Key Vault inaccessible), the system should degrade gracefully, implement appropriate fallback mechanisms, and recover automatically when services become available. +**Validates: Requirements 6.3** + +### Property 19: Azure Throttling Handling Resilience +*For any* Azure Service Bus throttling scenario, the system should handle rate limiting gracefully with appropriate backoff strategies and maintain message processing integrity. +**Validates: Requirements 6.4** + +### Property 20: Azure Network Partition Recovery +*For any* network partition scenario affecting Azure services, the system should detect the partition, implement appropriate circuit breaker behavior, and recover automatically when connectivity is restored. +**Validates: Requirements 6.5** + +### Property 21: Azurite Emulator Functional Equivalence +*For any* test scenario that runs successfully against real Azure services, the same test should run successfully against Azurite emulators with functionally equivalent results, allowing for performance differences due to emulation overhead. +**Validates: Requirements 7.1, 7.2, 7.3, 7.5** + +### Property 22: Azurite Performance Metrics Meaningfulness +*For any* performance test executed against Azurite emulators, the performance metrics should provide meaningful insights into system behavior patterns, even if absolute values differ from cloud services due to emulation overhead. +**Validates: Requirements 7.4** + +### Property 23: Azure CI/CD Environment Consistency +*For any* test suite, when executed in different environments (local Azurite, CI/CD, Azure cloud), the functional test results should be consistent, with only expected performance variations between environments. +**Validates: Requirements 8.1** + +### Property 24: Azure Test Resource Management Completeness +*For any* test execution requiring Azure resources, all resources created during testing should be automatically cleaned up after test completion, and resource creation should be idempotent to prevent conflicts. +**Validates: Requirements 8.2, 8.5** + +### Property 25: Azure Test Reporting Completeness +*For any* Azure test execution, the generated reports should contain all required Azure-specific metrics, error details, and analysis data, and should be accessible for historical trend analysis. +**Validates: Requirements 8.3** + +### Property 26: Azure Error Message Actionability +*For any* Azure test failure, the error messages and troubleshooting guidance should provide sufficient Azure-specific information to identify and resolve the underlying issue. +**Validates: Requirements 8.4** + +### Property 27: Azure Key Vault Access Policy Validation +*For any* Azure Key Vault operation, when access policies are configured, operations should succeed when proper policies are in place and fail appropriately when policies are insufficient, with clear error messages indicating required permissions. +**Validates: Requirements 9.3** + +### Property 28: Azure End-to-End Encryption Security +*For any* sensitive data transmitted through Azure services, the data should be encrypted end-to-end both in transit and at rest, with proper key management and no exposure of sensitive data in logs or intermediate storage. +**Validates: Requirements 9.4** + +### Property 29: Azure Security Audit Logging Completeness +*For any* security-related operation in Azure services (authentication, authorization, key access), appropriate audit logs should be generated with sufficient detail for security analysis and compliance requirements. +**Validates: Requirements 9.5** + +## Error Handling + +### Azure Service Failures +The testing framework handles various Azure service failure scenarios: + +- **Service Bus Unavailability**: Tests validate graceful degradation when Service Bus namespace or specific queues/topics are unavailable +- **Key Vault Inaccessibility**: Tests verify proper error handling for Key Vault connectivity issues or key unavailability +- **Managed Identity Failures**: Tests validate behavior when managed identity authentication fails or tokens expire +- **RBAC Permission Denials**: Tests verify appropriate error messages and fallback behavior for insufficient permissions +- **Network Connectivity Issues**: Tests simulate network partitions and validate retry behavior and circuit breaker patterns + +### Azure-Specific Error Conditions +The framework provides robust error handling for Azure-specific issues: + +- **Service Bus Throttling**: Automatic retry with exponential backoff when Service Bus rate limits are exceeded +- **Key Vault Rate Limiting**: Proper handling of Key Vault request throttling with appropriate backoff strategies +- **Session Lock Timeouts**: Handling of Service Bus session lock timeouts and automatic session renewal +- **Duplicate Detection Window**: Proper handling of messages outside the duplicate detection time window +- **Message Size Limits**: Validation and error handling for messages exceeding Service Bus size limits (256KB) + +### Test Environment Error Recovery +The testing framework includes safeguards against test environment failures: + +- **Azurite

systems. This guide explains how to configure idempotency services when using AWS or Azure cloud extensions. + +## Default Behavior (In-Memory) + +By default, SourceFlow automatically registers an in-memory idempotency service when you configure AWS or Azure cloud integration.

It simplifies the setup of message queues, topics, and subscriptions across AWS and Azure without dealing with low-level cloud service details. + +**Key Benefits:** +- **Type Safety** - Compile-time validation of command and event routing +- **Simplified Configuration** - Use short names instead of full URLs/ARNs +- **Automatic Resource Creation** - Queues, topics, and subscriptions created automatically +- **Intuitive API** - Natural, readable configuration with method chaining +- **Cloud Agnostic** - Same API works for both AWS and Azure + +### Architecture + +The Bus Configuration System consists of three main components: + +```mermaid +graph TB + A[Application Startup] --> B[BusConfigurationBuilder] + B --> C[BusConfiguration] + C --> D[Bootstrapper] + D --> E{Resource Creation} + E -->|AWS| F[SQS Queues] + E -->|AWS| G[SNS Topics] + E -->|Azure| H[Service Bus Queues] + E -->|Azure| I[Service Bus Topics] + D --> J[Dispatcher Registration] + J --> K[Listener Startup] +``` + +1. **BusConfigurationBuilder** - Entry point for building routing configuration using fluent API +2. **BusConfiguration** - Holds the complete routing configuration for commands and events +3. **Bootstrapper** - Hosted service that creates cloud resources and initializes routing at startup + +### Quick Start + +Here's a minimal example configuring command and event routing: + +```csharp +using SourceFlow.Cloud.AWS; +using Amazon; + +public void ConfigureServices(IServiceCollection services) +{ + services.UseSourceFlowAws( + options => { + options.Region = RegionEndpoint.USEast1; + }, + bus => bus + .Send + .Command(q => q.Queue("orders.fifo")) + .Raise + .Event(t => t.Topic("order-events")) + .Listen.To + .CommandQueue("orders.fifo") + .Subscribe.To + .Topic("order-events")); +} +``` + +### Configuration Sections + +The fluent API is organized into four intuitive sections: + +#### Send - Command Routing + +Configure which commands are sent to which queues: + +```csharp +bus => bus + .Send + .Command(q => q.Queue("orders.fifo")) + .Command(q => q.Queue("orders.fifo")) + .Command(q => q.Queue("inventory.fifo")) +``` + +**Best Practices:** +- Group related commands to the same queue for ordering guarantees +- Use `.fifo` suffix for queues requiring ordered processing +- Use short queue names only (e.g., "orders.fifo", not full URLs) + +#### Raise - Event Publishing + +Configure which events are published to which topics: + +```csharp +bus => bus + .Raise + .Event(t => t.Topic("order-events")) + .Event(t => t.Topic("order-events")) + .Event(t => t.Topic("shipping-events")) +``` + +**Best Practices:** +- Group related events to the same topic for fan-out messaging +- Use descriptive topic names that reflect the event domain +- Use short topic names only (e.g., "order-events", not full ARNs) + +#### Listen - Command Queue Listeners + +Configure which command queues the application listens to: + +```csharp +bus => bus + .Listen.To + .CommandQueue("orders.fifo") + .CommandQueue("inventory.fifo") +``` + +**Note:** At least one command queue must be configured when subscribing to topics. + +#### Subscribe - Topic Subscriptions + +Configure which topics the application subscribes to: + +```csharp +bus => bus + .Subscribe.To + .Topic("order-events") + .Topic("payment-events") + .Topic("shipping-events") +``` + +**How it works:** The bootstrapper automatically creates subscriptions that forward topic messages to your configured command queues. + +### Complete Example + +Here's a realistic scenario combining all four sections: + +```csharp +using SourceFlow.Cloud.AWS; +using Amazon; + +public class Startup +{ + public void ConfigureServices(IServiceCollection services) + { + // Register SourceFlow core + services.UseSourceFlow(Assembly.GetExecutingAssembly()); + + // Configure AWS cloud integration with Bus Configuration System + services.UseSourceFlowAws( + options => { + options.Region = RegionEndpoint.USEast1; + options.EnableEncryption = true; + options.KmsKeyId = "alias/sourceflow-key"; + }, + bus => bus + // Configure command routing + .Send + .Command(q => q.Queue("orders.fifo")) + .Command(q => q.Queue("orders.fifo")) + .Command(q => q.Queue("orders.fifo")) + .Command(q => q.Queue("inventory.fifo")) + .Command(q => q.Queue("payments.fifo")) + + // Configure event publishing + .Raise + .Event(t => t.Topic("order-events")) + .Event(t => t.Topic("order-events")) + .Event(t => t.Topic("order-events")) + .Event(t => t.Topic("inventory-events")) + .Event(t => t.Topic("payment-events")) + + // Configure command queue listeners + .Listen.To + .CommandQueue("orders.fifo") + .CommandQueue("inventory.fifo") + .CommandQueue("payments.fifo") + + // Configure topic subscriptions + .Subscribe.To + .Topic("order-events") + .Topic("payment-events") + .Topic("inventory-events")); + } +} +``` + +### Azure Configuration Example + +The same fluent API works for Azure Service Bus: + +```csharp +using SourceFlow.Cloud.Azure; + +public void ConfigureServices(IServiceCollection services) +{ + services.UseSourceFlowAzure( + options => { + options.FullyQualifiedNamespace = "myservicebus.servicebus.windows.net"; + options.UseManagedIdentity = true; + }, + bus => bus + .Send + .Command(q => q.Queue("orders")) + .Command(q => q.Queue("orders")) + .Raise + .Event(t => t.Topic("order-events")) + .Listen.To + .CommandQueue("orders") + .Subscribe.To + .Topic("order-events")); +} +``` + +### Bootstrapper Integration + +The bootstrapper is a hosted service that runs at application startup to initialize your cloud infrastructure: + +**What the Bootstrapper Does:** + +1. **Resolves Short Names** + - AWS: Converts short names to full SQS URLs and SNS ARNs + - Azure: Uses short names directly for Service Bus resources + +2. **Creates Missing Resources** + - Creates queues with appropriate settings (FIFO attributes, sessions, etc.) + - Creates topics for event publishing + - Creates subscriptions that forward topic messages to command queues + +3. **Validates Configuration** + - Ensures at least one command queue exists when subscribing to topics + - Validates queue and topic names follow cloud provider conventions + - Checks for configuration conflicts + +4. **Registers Dispatchers** + - Registers command and event dispatchers with resolved routing + - Configures listeners to start polling queues + +**Execution Timing:** The bootstrapper runs before listeners start, ensuring all routing is ready before message processing begins. + +**Development vs. Production:** +- **Development**: Let the bootstrapper create resources automatically for rapid iteration +- **Production**: Use infrastructure-as-code (CloudFormation, Terraform, ARM templates) for controlled deployments + +### FIFO Queue Configuration + +Use the `.fifo` suffix to enable ordered message processing: + +**AWS (SQS FIFO Queues):** +```csharp +.Send + .Command(q => q.Queue("orders.fifo")) +``` +- Enables content-based deduplication +- Enables message grouping by entity ID +- Guarantees exactly-once processing + +**Azure (Session-Enabled Queues):** +```csharp +.Send + .Command(q => q.Queue("orders.fifo")) +``` +- Enables session handling +- Groups messages by session ID (entity ID) +- Guarantees ordered processing per session + +### Best Practices + +1. **Command Routing Organization** + - Group related commands to the same queue for ordering + - Use separate queues for different bounded contexts + - Use FIFO queues when order matters + +2. **Event Routing Organization** + - Group related events to the same topic + - Use descriptive topic names reflecting the domain + - Design for fan-out to multiple subscribers + +3. **Queue and Topic Naming** + - Use lowercase with hyphens (e.g., "order-events") + - Use `.fifo` suffix for ordered processing + - Keep names short and descriptive + +4. **Resource Creation Strategy** + - Development: Use automatic creation for speed + - Staging: Mix of automatic and IaC + - Production: Use IaC for control and auditability + +5. **Testing** + - Unit test configuration without cloud services + - Integration test with LocalStack (AWS) or Azurite (Azure) + - Validate routing configuration in tests + +### Troubleshooting + +**Issue: Commands not being routed** +- Verify command is configured in Send section +- Check queue name matches Listen configuration +- Ensure bootstrapper completed successfully + +**Issue: Events not being received** +- Verify event is configured in Raise section +- Check topic subscription is configured +- Ensure at least one command queue is configured + +**Issue: Resources not created** +- Check cloud provider credentials and permissions +- Verify bootstrapper logs for errors +- Ensure queue/topic names follow cloud provider conventions + +**Issue: FIFO ordering not working** +- Verify `.fifo` suffix is used in queue name +- Check entity ID is properly set in commands +- Ensure message grouping is configured + +### Cloud-Specific Documentation + +For detailed cloud-specific information: +- **AWS**: See [AWS Cloud Extension Guide](.kiro/steering/sourceflow-cloud-aws.md) +- **Azure**: See [Azure Cloud Extension Guide](.kiro/steering/sourceflow-cloud-azure.md) +- **Testing**: See [Cloud Integration Testing](Cloud-Integration-Testing.md) + --- ## 🗂️ Persistence Options diff --git a/docs/SourceFlow.Stores.EntityFramework-README.md b/docs/SourceFlow.Stores.EntityFramework-README.md index c45482b..0560a13 100644 --- a/docs/SourceFlow.Stores.EntityFramework-README.md +++ b/docs/SourceFlow.Stores.EntityFramework-README.md @@ -5,6 +5,7 @@ Entity Framework Core persistence provider for SourceFlow.Net with support for S ## Features -

This is suitable for single-instance deployments. - -### AWS Example - -```csharp -services.UseSourceFlow(); - -services.UseSourceFlowAws( - options => { options.Region = RegionEndpoint.USEast1; }, - bus => bus - .Send.Command(q => q.Queue("orders.fifo")) - .Listen.To.CommandQueue("orders.fifo")); -``` - -### Azure Example - -```csharp -services.UseSourceFlow(); - -services.UseSourceFlowAzure( - options => - { - options.FullyQualifiedNamespace = "myservicebus.servicebus.windows.net"; - options.UseManagedIdentity = true; - }, - bus => bus - .Send.Command(q => q.Queue("orders")) - .Listen.To.CommandQueue("orders")); -``` - -## Multi-Instance Deployment (SQL-Based) - -For production deployments with multiple instances, use the SQL-based idempotency service to ensure duplicate detection across all instances. - -### Step 1: Install Required Package - -```bash -dotnet add package SourceFlow.Stores.EntityFramework -``` - -### Step 2: Register SQL-Based Idempotency - -#### AWS Configuration (Recommended Approach) - -Register the idempotency service before configuring AWS, and it will be automatically detected: - -```csharp -services.UseSourceFlow(); - -// Register Entity Framework stores and SQL-based idempotency -services.AddSourceFlowEfStores(connectionString); -services.AddSourceFlowIdempotency( - connectionString: connectionString, - cleanupIntervalMinutes: 60); - -// Configure AWS - will automatically use registered EF idempotency service -services.UseSourceFlowAws( - options => { options.Region = RegionEndpoint.USEast1; }, - bus => bus - .Send.Command(q => q.Queue("orders.fifo")) - .Listen.To.CommandQueue("orders.fifo")); -``` - -#### AWS Configuration (Alternative Approach) - -Use the optional `configureIdempotency` parameter to explicitly configure the idempotency service: - -```csharp -services.UseSourceFlow(); - -// Register Entity Framework stores -services.AddSourceFlowEfStores(connectionString); - -// Configure AWS with explicit idempotency configuration -services.UseSourceFlowAws( - options => { options.Region = RegionEndpoint.USEast1; }, - bus => bus - .Send.Command(q => q.Queue("orders.fifo")) - .Listen.To.CommandQueue("orders.fifo"), - configureIdempotency: services => - { - services.AddSourceFlowIdempotency(connectionString, cleanupIntervalMinutes: 60); - }); -``` - -#### Azure Configuration - -```csharp -services.UseSourceFlow(); - -// Register Entity Framework stores and SQL-based idempotency -services.AddSourceFlowEfStores(connectionString); -services.AddSourceFlowIdempotency( - connectionString: connectionString, - cleanupIntervalMinutes: 60); - -// Configure Azure - will use registered EF idempotency service -services.UseSourceFlowAzure( - options => - { - options.FullyQualifiedNamespace = "myservicebus.servicebus.windows.net"; - options.UseManagedIdentity = true; - }, - bus => bus - .Send.Command(q => q.Queue("orders")) - .Listen.To.CommandQueue("orders")); -``` - -### Step 3: Database Setup - -The `IdempotencyRecords` table will be created automatically on first use. Alternatively, you can create it manually: - -```sql -CREATE TABLE IdempotencyRecords ( - IdempotencyKey NVARCHAR(500) PRIMARY KEY, - ProcessedAt DATETIME2 NOT NULL, - ExpiresAt DATETIME2 NOT NULL, - MessageType NVARCHAR(500) NULL, - CloudProvider NVARCHAR(50) NULL -); - -CREATE INDEX IX_IdempotencyRecords_ExpiresAt - ON IdempotencyRecords(ExpiresAt); -``` - -## Custom Idempotency Service - -You can provide a custom idempotency implementation using the optional `configureIdempotency` parameter available in AWS (and coming soon to Azure). - -### AWS Example - -```csharp -services.UseSourceFlowAws( - options => { options.Region = RegionEndpoint.USEast1; }, - bus => bus.Send.Command(q => q.Queue("orders.fifo")), - configureIdempotency: services => - { - services.AddScoped(); - }); -``` - -### Azure Example (Coming Soon) - -Azure will support the `configureIdempotency` parameter in a future release. For now, register the idempotency service before calling `UseSourceFlowAzure`: - -```csharp -services.AddScoped(); - -services.UseSourceFlowAzure( - options => { options.FullyQualifiedNamespace = "myservicebus.servicebus.windows.net"; }, - bus => bus.Send.Command(q => q.Queue("orders"))); -``` - -## Fluent Builder API (Alternative Configuration) - -SourceFlow provides a fluent `IdempotencyConfigurationBuilder` for more expressive configuration. This builder is particularly useful when you want to configure idempotency independently of cloud provider setup. - -### Using the Builder with Entity Framework - -**Important**: The `UseEFIdempotency` method requires the `SourceFlow.Stores.EntityFramework` package to be installed. The builder uses reflection to call the registration method, avoiding a direct dependency in the core package. - -```csharp -// First, ensure the package is installed: -// dotnet add package SourceFlow.Stores.EntityFramework - -var idempotencyBuilder = new IdempotencyConfigurationBuilder() - .UseEFIdempotency(connectionString, cleanupIntervalMinutes: 60); - -// Apply configuration to service collection -idempotencyBuilder.Build(services); - -// Then configure cloud provider -services.UseSourceFlowAws( - options => { options.Region = RegionEndpoint.USEast1; }, - bus => bus.Send.Command(q => q.Queue("orders.fifo"))); -``` - -If the EntityFramework package is not installed, you'll receive a clear error message: -``` -SourceFlow.Stores.EntityFramework package is not installed. -Install it using: dotnet add package SourceFlow.Stores.EntityFramework -``` - -### Using the Builder with In-Memory - -```csharp -var idempotencyBuilder = new IdempotencyConfigurationBuilder() - .UseInMemory(); - -idempotencyBuilder.Build(services); -``` - -### Using the Builder with Custom Implementation - -```csharp -// With type parameter -var idempotencyBuilder = new IdempotencyConfigurationBuilder() - .UseCustom(); - -// Or with factory function -var idempotencyBuilder = new IdempotencyConfigurationBuilder() - .UseCustom(provider => - { - var logger = provider.GetRequiredService>(); - return new MyCustomIdempotencyService(logger); - }); - -idempotencyBuilder.Build(services); -``` - -### Builder Methods - -| Method | Description | Use Case | -|--------|-------------|----------| -| `UseEFIdempotency(connectionString, cleanupIntervalMinutes)` | Configure Entity Framework-based idempotency (uses reflection to avoid direct dependency) | Multi-instance production deployments | -| `UseInMemory()` | Configure in-memory idempotency | Single-instance or development environments | -| `UseCustom()` | Register custom implementation by type | Custom idempotency logic with DI | -| `UseCustom(factory)` | Register custom implementation with factory | Custom idempotency with complex initialization | -| `Build(services)` | Apply configuration to service collection (uses TryAddScoped for default) | Final step to register services | - -### Builder Implementation Details - -- **Reflection-Based EF Integration**: `UseEFIdempotency` uses reflection to call `AddSourceFlowIdempotency` from the EntityFramework package, avoiding a direct dependency in the core SourceFlow package -- **Lazy Registration**: The `Build` method only registers services if no configuration was set, using `TryAddScoped` to avoid overwriting existing registrations -- **Error Handling**: Clear error messages guide users when required packages are missing or methods cannot be found -- **Service Lifetime**: All idempotency services are registered as Scoped to match dispatcher lifetimes - -### Builder Benefits - -- **Explicit Configuration**: Clear, readable idempotency setup -- **Reusable**: Create builder instances for different environments -- **Testable**: Easy to mock and test configuration logic -- **Type-Safe**: Compile-time validation of configuration -- **Flexible**: Mix and match with direct service registration - -## Configuration Options - -### SQL-Based Idempotency Options - -```csharp -services.AddSourceFlowIdempotency( - connectionString: "Server=...;Database=...;", - cleanupIntervalMinutes: 60); // Cleanup interval (default: 60 minutes) -``` - -### Custom Database Provider - -For databases other than SQL Server: - -```csharp -services.AddSourceFlowIdempotencyWithCustomProvider( - configureContext: options => options.UseNpgsql(connectionString), - cleanupIntervalMinutes: 60); -``` - -## How It Works - -### Registration Flow (AWS) - -1. **UseSourceFlowAws** is called with optional `configureIdempotency` parameter -2. If `configureIdempotency` parameter is provided, it's executed to register the idempotency service -3. If `configureIdempotency` is null, checks if `IIdempotencyService` is already registered -4.

SensitiveDataMasker Missing Methods -**Files Affected:** -- `Integration/KeyVaultEncryptionTests.cs` (lines 241, 270, 291, 292) - -**Problem:** Tests call methods that don't exist: -- `MaskSensitiveData(object)` -- `GetSensitiveProperties(Type)` -- `MaskCreditCardNumbers(string)` -- `MaskCVV(string)` - -**Solution:** Either: -1. Implement these methods in `SensitiveDataMasker` class -2. Remove these tests (they test functionality that doesn't exist in the actual codebase) -3.

The core issue is that LocalStack services (sqs, sns, kms, iam) do not report "available" status within the current 30-second timeout window in containerized CI environments, despite working correctly in local development. Additionally, parallel test execution causes port conflicts when multiple tests attempt to start LocalStack containers simultaneously on port 4566. + +The fix strategy involves: +1. Increasing health check timeouts and retry logic for CI environments +2. Implementing external LocalStack instance detection to reuse existing containers +3. Enhancing xUnit collection fixtures to enforce proper container sharing +4. Adding CI-specific configuration with longer timeouts and more retries +5. Improving wait strategies to account for slower container initialization in GitHub Actions + +## Glossary + +- **Bug_Condition (C)**: The condition that triggers the bug - when LocalStack containers start in GitHub Actions CI and health checks timeout before services report "available" status +- **Property (P)**: The desired behavior when LocalStack starts in CI - all services should report "available" within a reasonable timeout appropriate for CI environments +- **Preservation**: Existing local development test behavior that must remain unchanged by the fix +- **LocalStackManager**: The class in `tests/SourceFlow.Cloud.AWS.Tests/TestHelpers/LocalStackManager.cs` that manages LocalStack container lifecycle +- **LocalStackTestFixture**: The xUnit fixture in `tests/SourceFlow.Cloud.AWS.Tests/TestHelpers/LocalStackTestFixture.cs` that provides shared LocalStack instances for tests +- **Health Check Endpoint**: The `/_localstack/health` endpoint that returns service status information +- **Service Ready State**: When a LocalStack service reports "available" or "running" status in the health check response +- **CI Environment**: GitHub Actions containerized environment with different performance characteristics than local development +- **Port Conflict**: When multiple containers attempt to bind to the same port (4566) simultaneously + +## Bug Details + +### Fault Condition + +The bug manifests when LocalStack containers start in GitHub Actions CI environments and the health check endpoint `/_localstack/health` does not return "available" status for all configured services (sqs, sns, kms, iam) within the 30-second timeout window.

This includes: +- Local development test execution +- Tests running against real AWS services (not LocalStack) +- Unit tests that don't require LocalStack +- Tests that successfully complete within 30 seconds + +## Hypothesized Root Cause + +Based on the bug description and code analysis, the most likely issues are: + +1. **Insufficient Timeout for CI Environments**: The current 30-second `HealthCheckTimeout` is adequate for local development but insufficient for GitHub Actions containerized environments where container startup and service initialization are slower due to: + - Shared compute resources in CI runners + - Network latency for pulling container images + - Slower disk I/O in virtualized environments + - Cold start overhead for LocalStack services + +2. **Missing External Instance Detection**: The `LocalStackManager.StartAsync` method checks for external LocalStack instances with a 3-second timeout in `LocalStackTestFixture`, but this check may be: + - Too short to reliably detect running instances + - Not consistently applied across all test entry points + - Not properly handling the case where an instance is starting but not yet ready + +3. **Inadequate xUnit Collection Sharing**: Tests use `[Collection("AWS Integration Tests")]` attribute but may not be properly configured with a collection fixture, causing xUnit to: + - Create separate fixture instances per test class + - Not enforce sequential execution within the collection + - Allow parallel execution that triggers port conflicts + +4. **Insufficient Health Check Retry Logic**: The current retry configuration (`MaxHealthCheckRetries = 10`, `HealthCheckRetryDelay = 2 seconds`) provides only 20 seconds of actual retry time, which is: + - Less than the 30-second timeout (due to HTTP request overhead) + - Insufficient for services that take 40-60 seconds to initialize in CI + - Not adaptive to CI environment performance characteristics + +5. **Wait Strategy Limitations**: The Testcontainers wait strategy checks for HTTP 200 OK on health endpoints but doesn't: + - Parse the JSON response to verify service "available" status + - Distinguish between "initializing" and "available" states + - Provide sufficient delay after container start before health checks + +## Correctness Properties + +Property 1: Fault Condition -
