From 50134682b4fb9db254a8b27e1ee20c956e35bbff Mon Sep 17 00:00:00 2001 From: Jeffrey Phillips Freeman Date: Wed, 11 Mar 2026 23:21:53 +0000 Subject: [PATCH 1/3] refactor(test): remove mock LLM providers from Robot Framework integration tests MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Replaced MockAIProvider and FakeListLLM with real LLM provider calls (ChatAnthropic/ChatOpenAI) in 5 Robot Framework files. Test assertions updated to handle non-deterministic LLM responses by verifying structure and completion rather than exact content. LLM model used: ChatAnthropic(model="claude-3-haiku-20240307") — chosen as the fastest and cheapest Anthropic model for integration testing. Files modified: - robot/database_integration.robot: Replaced MockAIProvider() with ProviderRegistry.create_ai_provider(provider_type="anthropic") in End-To-End Database Workflow and Create Plan With Service keyword. - robot/helper_plan_generation.py: Replaced FakeListLLM with ChatAnthropic. - robot/plan_generation_graph.robot: Replaced FakeListLLM in all 18 test cases with ChatAnthropic. Tests verify graph structure, node presence, state shape, and workflow completion rather than exact LLM output. - robot/context_analysis_agent.robot: Replaced FakeListLLM in 2 inline test scripts with ChatAnthropic. - robot/helper_context_analysis.py: Replaced all 5 FakeListLLM sites with a shared _create_llm() factory returning ChatAnthropic. Additional fix: - src/cleveragents/application/services/plan_service.py: Wrapped the provider name/model_id setter calls in try/except to handle read-only properties on real LangChainChatProvider implementations (bug exposed by removing MockAIProvider which had mutable name/model_id setters). Assertion strategy: All tests continue to verify structural correctness (state keys, node names, type checks) and successful workflow completion. No exact-string assertions on LLM output content.

7d38ea8b5da0e6caf33c3bf42069d82874d0db1b Mon Sep 17 00:00:00 2001 From: Jeffrey Phillips Freeman Date: Thu, 12 Mar 2026 05:01:50 +0000 Subject: [PATCH 3/3] refactor(test): replace mock test doubles with real MCP transport and dependencies Implemented real StdioMCPTransport for MCP server communication via stdio subprocess with JSON-RPC framing. Created mcp_echo_server.py fixture providing echo and add tools for integration tests. Replaced InMemoryContentReader with real LocationContentReader backed by temporary files. Replaced MockMCPTransport with real StdioMCPTransport connecting to the fixture MCP server. Renamed _testing_stubs.py to _test_utils.py (retaining only the pure parse_lsp_responses utility). Fixed MCPToolAdapter.invoke() to handle real MCP content list responses. Added env-gating for LLM integration tests (llm-required tag excluded when ANTHROPIC_API_KEY is absent).
