From ddbea0bdcab5af2daad3ff491cf22ace3bf57286 Mon Sep 17 00:00:00 2001 From: Cursor Agent Date: Sat, 8 Aug 2026 12:26:28 +0000 Subject: [PATCH] feat(test): add LLM test support abstraction for graceful skipping Add a new test support package with utilities for handling LLM-dependent tests: - @RequiresLlm annotation: marks tests that need LLM configuration - Supports chat and embedding requirements independently - Tests are skipped (not failed) when LLM is not configured - Works at class or method level - LlmAvailabilityCondition: JUnit 5 ExecutionCondition - Checks DEEPSQL_CHAT_* and DEEPSQL_EMBEDDING_* environment variables - Uses the same resolution logic as production LlmConfigResolver - LlmTestSupport: Spring component for integration tests - Uses actual LlmConfigResolver to check both env vars and DB config - Provides requireChat(), requireEmbedding() methods for test assertions - Includes diagnostic describeConfiguration() method Updated BaseIntegrationTest: - Autowires LlmTestSupport for integration tests - Adds convenience methods: isChatLlmAvailable(), requireChatLlm(), etc. Updated ChatPromptIntegrationTest: - Added @RequiresLlm(chat = true) annotation - All 23 tests now skip gracefully when LLM is not configured - Improved Javadoc documentation This allows the test suite to run cleanly in environments without LLM credentials, while still validating LLM-dependent functionality when credentials are available.
