Test Organization + +- **Keep tests close to code**: Mirror the source structure in test directories +- **Use descriptive names**: Test names should clearly describe what they test +- **Group related tests**: Use test classes to group related functionality + +### 2. Test Data + +- **Use fixtures**: Create reusable test data with pytest fixtures +- **Avoid hardcoded values**: Use factories or builders for test data generation +- **Clean up after tests**: Ensure tests don't affect each other + +### 3. Mocking Strategy + +```python +# Good: Mock external dependencies +@patch('service.retrieval.httpx.AsyncClient') +async def test_retrieval_with_mock(mock_client): + # Test implementation + pass + +# Good: Mock at the right level +@patch('service.llm_client.OpenAIClient.generate') +async def test_agent_workflow(mock_generate): + # Test workflow logic without hitting LLM API + pass + +# Avoid: Over-mocking (mocking everything) +# Avoid: Under-mocking (hitting real APIs in unit tests) +``` + +### 4. Async Testing + +```python +# Proper async test setup +@pytest.mark.asyncio +async def test_async_function(): + result = await async_function() + assert result is not None + +# Use async context managers +@pytest.mark.asyncio +async def test_with_async_client(): + async with AsyncClient() as client: + response = await client.get("/") + assert response.status_code == 200 +``` + +### 5. Performance Testing + +- **Set realistic timeouts**: Don't make tests too strict or too loose +- **Test under load**: Verify system behavior with concurrent requests +- **Monitor resource usage**: Check memory leaks and CPU usage + +### 6. Error Testing + +```python +def test_error_handling(): + """Test that errors are handled gracefully.""" + + # Test invalid input + with pytest.raises(ValueError): + function_with_validation("") + + # Test network errors + with patch('httpx.post', side_effect=httpx.ConnectError("Connection failed")): + result = robust_function() + assert result["error"] is not None +``` + +--- + +This testing guide provides a comprehensive framework for ensuring the quality and reliability of the Agentic RAG system. Regular testing at all levels helps maintain code quality and prevents regressions as the system evolves. diff --git a/vw-agentic-rag/docs/topics/AI_SDK_UI.md b/vw-agentic-rag/docs/topics/AI_SDK_UI.md

Node Function: `user_manual_agent_node`** +- Implements the "detect-first-then-stream" strategy for optimal multi-round behavior +- Supports autonomous tool calling with user manual tools +- Handles streaming responses with HTML comment filtering +- Manages tool rounds and conversation trimming +- Uses user manual specific system prompt from configuration + +### 2. **User Manual Tools Integration** +- Uses `service/graph/user_manual_tools.py` for tool schemas and tools mapping +- Specifically designed for user manual retrieval operations +- Integrated with `retrieve_system_usermanual` tool + +### 3. **Routing Logic: `user_manual_should_continue`** +- Routes to `user_manual_tools` when tool calls are detected +- Routes to `post_process` when no tool calls (final synthesis completed) +- Routes to `user_manual_agent` for next round after tool execution + +### 4. **Tool Execution: `run_user_manual_tools_with_streaming`** +- Executes user manual tools with streaming support +- Supports parallel execution (though typically only one tool for user manual) +- Enhanced error handling with proper error categories +- Streaming events for tool start, result, and error states + +### 5. **System Prompt Integration** +- Uses `user_manual_prompt` from `llm_prompt.yaml` configuration +- Formats prompt with conversation history, context content, and current query +- Maintains grounding requirements and response structure from original prompt + +## Technical Implementation Details + +### Agent Node Features +- **Tool Round Management**: Tracks and limits tool calling rounds +- **Conversation Trimming**: Manages context length automatically +- **Streaming Support**: Real-time token streaming with HTML comment filtering +- **Error Handling**:

return await user_manual_agent_node(state, config) +``` + +## Testing Results + +### Functionality Tests +โœ… **Basic Agent Operation**: Tool detection and calling works correctly +โœ… **Tool Execution**: User manual retrieval executes successfully +โœ… **Routing Logic**: Proper routing between agent, tools, and post-process +โœ… **Multi-Round Workflow**: Complete workflow with tool rounds and final synthesis +โœ… **Streaming Support**: Real-time response streaming with proper formatting + +### Integration Tests +โœ… **Configuration Loading**: User manual prompt loaded correctly +โœ… **Tool Integration**: User manual tools properly integrated +โœ… **Error Handling**: Graceful error handling and recovery +โœ… **State Management**: Proper state updates and tracking + +## Usage Example + +```python +# Create state for user manual query +state = { + "messages": [HumanMessage(content="How do I reset my password?")], + "session_id": "session_1", + "intent": "User_Manual_RAG", +

The system processes documents through a well-defined pipeline that transforms raw documents into searchable, vectorized content. + +### Architectural Patterns + +**Service Factory Pattern**: The system uses a centralized ServiceFactory to manage dependencies and service creation. This pattern ensures consistent configuration across all services and enables easy testing through dependency injection. + +**Repository Pattern**: Data access is abstracted through repository interfaces, allowing for different storage backends and simplified testing with mock implementations. + +**Command Pattern**: Document processing tasks are encapsulated as commands that can be queued, retried, and executed asynchronously. + +**Pipeline Pattern**: The document processing workflow follows a clear pipeline with distinct stages: extraction, hierarchy fixing, chunking, vectorization, and indexing. + +### High-Level Architecture + +The high-level architecture represents a distributed, service-oriented system designed for scalable document processing and intelligent content extraction. The architecture emphasizes separation of concerns, fault tolerance, and cloud-native principles to handle enterprise-scale document processing workloads. + +#### Architectural Overview + +**Multi-Layered Design**: The system is organized into distinct functional layers that separate data ingestion, processing logic, AI services, and storage concerns. This layered approach enables independent scaling, testing, and maintenance of different system components. + +**Service-Oriented Architecture**: Each major functional area is implemented as a distinct service or component group, enabling independent deployment, scaling, and maintenance. Services communicate through well-defined interfaces and can be replaced or upgraded independently. + +**Cloud-Native Integration**: The architecture leverages Azure cloud services for AI processing, storage, and search capabilities while maintaining abstraction layers that enable portability and testing flexibility. + +**Event-Driven Processing**: The system follows an event-driven model where document processing is triggered by events (new documents, configuration changes, etc.) and progresses through a series of processing stages with clear state transitions. + +#### System Components and Responsibilities + +**Data Sources Layer**: Manages document ingestion from various sources including Azure Blob Storage and local file systems. This layer handles authentication, access control, and metadata extraction from source systems. It provides a unified interface for document discovery regardless of the underlying storage mechanism. + +**Processing Engine Layer**: Orchestrates the entire document processing workflow through a hierarchical task management system. The Main Application serves as the central coordinator, while the Task Processor manages work distribution and the Document Task Processor handles individual document processing operations with full state tracking and error recovery. + +**AI Services Layer**: Provides intelligent document processing capabilities through integration with Azure AI services and optional Vision LLM systems. These services handle complex operations like OCR, layout analysis, content extraction, and embedding generation. The modular design allows for easy integration of additional AI services or replacement of existing ones. + +**Processing Pipeline Layer**: Implements the core document transformation logic through a series of processing stages. Each stage has specific responsibilities: content extraction converts raw documents to structured text, hierarchy fixing normalizes document structure, chunking creates manageable content segments, and vector generation produces searchable embeddings. + +**Storage & Search Layer**: Manages persistent data storage and search capabilities through a combination of relational database storage for metadata and state management, Azure AI Search for vector-based content search, and blob storage for processed content and temporary files. + +#### Data Flow and Integration Patterns + +**Asynchronous Processing Flow**: Documents flow through the system asynchronously, enabling high throughput and efficient resource utilization. Each processing stage can operate independently, with clear handoff points and state persistence between stages. + +**Fault-Tolerant Design**: The architecture includes comprehensive error handling and recovery mechanisms at every level. Failed operations are tracked, logged, and can be retried with exponential backoff. The system maintains processing state to enable recovery from failures without losing work. + +**Scalability Patterns**: The architecture supports both vertical and horizontal scaling through stateless processing components, connection pooling, and queue-based work distribution. Different components can be scaled independently based on their specific resource requirements and bottlenecks. + +**Configuration-Driven Behavior**: The system behavior is largely controlled through configuration rather than code changes, enabling flexible deployment across different environments and use cases without requiring code modifications or redeployment. + +```mermaid +graph TB + subgraph "Data Sources" + DS[Document Sources

This approach maximizes throughput and allows for efficient resource utilization across multiple processing nodes. + +**Stateful Processing**: Each document's processing state is tracked in the database, enabling recovery from failures and preventing duplicate processing. The system maintains detailed status information and processing history. + +**Batch Operations**: Where possible, operations are batched to improve efficiency. This is particularly important for operations like embedding generation and search index uploads. + +**Retry Logic**: Failed operations are automatically retried with exponential backoff.

This design emphasizes fault tolerance, scalability, and efficient resource utilization throughout the processing lifecycle. + +#### Design Principles for Data Flow + +**Pipeline-Based Processing**: The data flow follows a clear pipeline pattern where each stage has specific responsibilities and well-defined inputs and outputs. This design enables parallel processing, easier debugging, and modular testing of individual stages. + +**Decision Points and Routing**: The architecture includes intelligent decision points that route documents through appropriate processing paths based on their characteristics. This ensures optimal processing strategies for different document types while maintaining a unified interface. + +**State Management**: Processing state is carefully managed throughout the pipeline, with persistent state stored in the database and transient state maintained in memory. This approach enables recovery from failures at any point in the pipeline. + +**Resource Optimization**: The flow is designed to minimize resource usage through efficient batching, connection reuse, and memory management. Processing stages are optimized to balance throughput with resource consumption. + +#### Processing Flow Stages + +**Initialization Phase**: The system performs comprehensive initialization including configuration validation, database connectivity checks, and service authentication. This phase ensures that all dependencies are available before processing begins. + +**Discovery and Task Creation**: Document sources are scanned to identify new or modified documents that require processing. Tasks are created based on configured criteria such as file modification dates and processing history. + +**Format Detection and Routing**: Documents are analyzed to determine their format and complexity, enabling the system to select the most appropriate extraction method. This intelligent routing ensures optimal processing quality and efficiency. + +**Content Extraction**: Multiple extraction paths are available depending on document characteristics.

Each area implements sophisticated algorithms to ensure high-quality output. + +### Design Principles for Document Processing + +**Format-Agnostic Processing**: The system handles multiple document formats through a unified interface. Different extractors are used based on document type, but all produce a standardized Document object. + +**Intelligent Content Analysis**: Before processing, the system analyzes document structure to determine the optimal processing strategy. This includes detecting header hierarchies, identifying figures and tables, and understanding document layout. + +**Quality Assurance**: Each processing stage includes validation and quality checks. For example, the hierarchy fixer validates that document structure is logical and coherent before proceeding to chunking. + +**Metadata Preservation**: Throughout the processing pipeline, important metadata is preserved and enriched. This includes document properties, processing timestamps, and structural information. + +### Document Extraction Logic + +The document extraction logic is the foundation of the processing pipeline. It handles the complex task of converting various document formats into structured, searchable content while preserving important layout and formatting information. + +**Multi-Modal Processing**: The system supports both traditional OCR-based extraction and advanced vision-language model processing. The choice of extraction method depends on document complexity and available resources. + +**Feature Detection**: Azure Document Intelligence features are selectively enabled based on document characteristics and configuration. This includes high-resolution OCR for detailed documents, formula extraction for technical content, and figure extraction for visual elements. + +**Content Structure Preservation**: The extraction process maintains document structure through markdown formatting, preserving headers, lists, tables, and other formatting elements that provide context for the content. + +**Error Handling and Fallbacks**: If advanced extraction features fail, the system falls back to basic extraction methods to ensure that content is not lost due to processing errors. + +```mermaid +flowchart TD + DOC[Document Input] --> DETECT[Detect Format] + + DETECT --> PDF{PDF?} + DETECT --> IMG{Image?} + DETECT --> OFFICE{Office Doc?} + DETECT --> TEXT{Text File?} + + PDF -->|Yes| DI_PDF[Azure DI Layout Model] + IMG -->|Yes| RESIZE[Resize if Needed] + OFFICE -->|Yes| CONVERT[Convert to Supported Format] + TEXT -->|Yes| DIRECT[Direct Content Read] + + RESIZE --> DI_IMG[Azure DI OCR + Layout] + CONVERT --> DI_OFFICE[Azure DI Document Analysis] + + DI_PDF --> FEATURES[Apply DI Features] + DI_IMG --> FEATURES + DI_OFFICE --> FEATURES + + FEATURES --> HIGH_RES{High Resolution OCR?} + FEATURES --> FORMULAS{Extract Formulas?} + FEATURES --> FIGURES{Extract Figures?} + + HIGH_RES -->|Yes| ENABLE_HIRES[Enable High-Res OCR] + FORMULAS -->|Yes| ENABLE_FORMULAS[Enable Formula Extraction] + FIGURES -->|Yes| ENABLE_FIGURES[Enable Figure Extraction] + + ENABLE_HIRES --> PROCESS_DI[Process with Azure DI] + ENABLE_FORMULAS --> PROCESS_DI + ENABLE_FIGURES --> PROCESS_DI + HIGH_RES -->|No| PROCESS_DI + FORMULAS -->|No| PROCESS_DI + FIGURES -->|No| PROCESS_DI + + DIRECT --> EXTRACT_META[Extract Metadata] + PROCESS_DI --> EXTRACT_CONTENT[Extract Content + Structure] + + EXTRACT_CONTENT --> EXTRACT_META + EXTRACT_META --> RESULT[Document Object] + + style DOC fill:#e3f2fd + style RESULT fill:#c8e6c9 + style PROCESS_DI fill:#fff3e0 +``` + +### Chunking Strategy + +The chunking strategy is critical for creating meaningful, searchable segments from large documents. The system implements intelligent chunking that respects document structure while maintaining optimal chunk sizes for search and retrieval. + +**Hierarchy-Aware Chunking**: The system analyzes document structure and uses markdown headers to create logical chunks. This ensures that related content stays together and that chunks maintain contextual coherence. + +**Adaptive Chunking**: Chunk boundaries are determined by both content structure and token limits. The system balances the need for complete thoughts with search engine constraints. + +**Overlap Strategy**: Configurable token overlap between chunks ensures that important information at chunk boundaries is not lost during retrieval operations. + +**Token Management**: Precise token counting using tiktoken ensures that chunks stay within specified limits while maximizing content density. + +```mermaid +flowchart TD + CONTENT[Extracted Content] --> HIERARCHY_FIX{Apply Hierarchy Fix?} + + HIERARCHY_FIX -->|Yes| FIX[Fix Header Hierarchy] + HIERARCHY_FIX -->|No| CHUNK_STRATEGY[Determine Chunking Strategy] + + FIX --> ANALYZE[Analyze Document Structure] + ANALYZE --> CHUNK_STRATEGY + + CHUNK_STRATEGY --> MARKDOWN{Markdown Headers?} + CHUNK_STRATEGY --> RECURSIVE{Use Recursive Split?} + + MARKDOWN -->|Yes| HEADER_SPLIT[Markdown Header Splitter] + MARKDOWN -->|No| RECURSIVE + RECURSIVE -->|Yes| CHAR_SPLIT[Recursive Character Splitter] + + HEADER_SPLIT --> CONFIG[Apply Chunk Configuration] + CHAR_SPLIT --> CONFIG + + CONFIG --> SIZE[Chunk Size: 2048 tokens] + CONFIG --> OVERLAP[Token Overlap: 128] + + SIZE --> SPLIT[Split Document] + OVERLAP --> SPLIT + + SPLIT --> VALIDATE[Validate Chunk Sizes] + VALIDATE --> METADATA[Add Chunk Metadata] + + METADATA --> RESULT[Chunked Documents] + + style CONTENT fill:#e3f2fd + style RESULT fill:#c8e6c9 + style FIX fill:#fff3e0 + style SPLIT fill:#f3e5f5 +``` + +### Indexing and Search Integration + +The indexing and search integration component handles the final stage of the processing pipeline, converting processed documents into searchable vector representations and uploading them to Azure AI Search. + +**Vector Generation**: The system generates high-quality embeddings using Azure OpenAI services. Multiple vector fields can be configured to support different search scenarios (content-based, metadata-based, etc.). + +**Batch Processing**: Documents are processed in configurable batches to optimize upload performance and manage API rate limits effectively. + +**Schema Management**: The system automatically creates and manages search index schemas based on configuration files, ensuring that all required fields and vector configurations are properly set up. + +**Error Recovery**: Failed uploads are tracked and retried, with detailed logging to help diagnose and resolve issues. The system can recover from partial batch failures without losing processed content. + +```mermaid +flowchart TD + CHUNKS[Document Chunks] --> EMBED[Generate Embeddings] + + EMBED --> OPENAI[Azure OpenAI API] + OPENAI --> VECTORS[Vector Embeddings] + + VECTORS --> PREPARE[Prepare Index Documents] + PREPARE --> METADATA[Add Metadata Fields] + + METADATA --> CUSTOM[Add Custom Fields] + CUSTOM --> BATCH[Create Upload Batches] + + BATCH --> SIZE[Batch Size: 50 docs] + SIZE --> UPLOAD[Upload to Azure AI Search] + + UPLOAD --> SUCCESS{Upload Successful?} + SUCCESS -->|Yes| UPDATE_STATUS[Update Success Status] + SUCCESS -->|No| RETRY[Retry Upload] + + RETRY --> MAX_RETRIES{Max Retries Reached?} + MAX_RETRIES -->|No| UPLOAD + MAX_RETRIES -->|Yes| ERROR[Mark as Failed] + + UPDATE_STATUS --> NEXT_BATCH{More Batches?} + NEXT_BATCH -->|Yes| BATCH + NEXT_BATCH -->|No| COMPLETE[Index Complete] + + ERROR --> LOG[Log Error Details] + LOG --> COMPLETE + + style CHUNKS fill:#e3f2fd + style COMPLETE fill:#c8e6c9 + style EMBED fill:#fff3e0 + style UPLOAD fill:#f3e5f5 + style ERROR fill:#ffcdd2 +``` + +## Database Schema + +The database schema is designed to support scalable document processing operations while maintaining data integrity and enabling efficient querying.
