+``` + +## Auto-Mock System + +The auto-mock system provides a powerful framework for testing workflows that contain nodes requiring third-party services (LLM, APIs, tools, etc.) without making actual external calls. This enables: + +- **Fast test execution** - No network latency or API rate limits +- **Deterministic results** - Consistent outputs for reliable testing +- **Cost savings** - No API usage charges during testing +- **Offline testing** - Tests can run without internet connectivity +- **Error simulation** - Test error handling without triggering real failures + +## Architecture + +The auto-mock system consists of three main components: + +### 1. MockNodeFactory (`test_mock_factory.py`) + +- Extends `DifyNodeFactory` to intercept node creation +- Automatically detects nodes requiring third-party services +- Returns mock node implementations instead of real ones +- Supports registration of custom mock implementations + +### 2. Mock Node Implementations (`test_mock_nodes.py`) + +- `MockLLMNode` - Mocks LLM API calls (OpenAI, Anthropic, etc.) +- `MockAgentNode` - Mocks agent execution +- `MockToolNode` - Mocks tool invocations +- `MockKnowledgeRetrievalNode` - Mocks knowledge base queries +- `MockHttpRequestNode` - Mocks HTTP requests +- `MockParameterExtractorNode` - Mocks parameter extraction +- `MockDocumentExtractorNode` - Mocks document processing +- `MockQuestionClassifierNode` - Mocks question classification + +### 3.
