Summary of Changes
Hello @MervinPraison, I'm Gemini Code Assist1! I'm currently reviewing this pull request and will post my feedback shortly. In the meantime, here's a summary to help you and other reviewers quickly get up to speed!
This pull request resolves an issue in the RAG integration tests by adjusting them to correctly account for the lazy loading pattern of knowledge processing. The changes ensure that tests validate the intended behavior of the RAG agent, preserving performance optimizations while accurately verifying functionality.
Highlights
- Test Fixes: Corrected two RAG integration tests (
test_agent_with_knowledge_configandtest_ollama_rag_integration) that were failing due to incorrect assumptions about immediate knowledge availability. The tests now properly validate the lazy loading pattern. - Lazy Loading Validation: Modified the tests to explicitly check for the lazy loading state (e.g.,
_knowledge_sources is not Noneand_knowledge_processed == False) before manually triggering knowledge processing via_ensure_knowledge_processed(), and then asserting that knowledge is available.

Code Review
This pull request fixes two integration tests for RAG functionality to correctly handle the new lazy loading pattern for knowledge processing. The changes are correct and achieve the goal. My review includes suggestions to make the tests more robust by testing the public API behavior instead of internal implementation details, which will improve long-term maintainability.

Thanks for fixing this test to account for lazy loading. The logic is correct.
However, by directly accessing private attributes (_knowledge_sources, _knowledge_processed) and calling a private method (_ensure_knowledge_processed), this test is tightly coupled to the internal implementation of the Agent class. This can make it brittle to future refactoring. The PR description mentions moving away from testing implementation details, and this is a great opportunity to align with that goal.
A more robust approach is to test the public behavior: that knowledge processing is triggered by a public method like chat(). This ensures the test validates the agent's contract, not its internal mechanics. You could achieve this by mocking the expensive part of the chat method.
| # With lazy loading, knowledge is None until first use | |
| assert agent._knowledge_sources is not None | |
| assert agent._knowledge_processed == False | |
| # Trigger knowledge processing | |
| agent._ensure_knowledge_processed() | |
| assert agent.knowledge is not None | |
| # With lazy loading, knowledge is None until first use. Test this initial state. | |
| assert agent.knowledge is None | |
| assert agent._knowledge_processed is False | |
| # Trigger knowledge processing via a public method, mocking the expensive part. | |
| with patch.object(agent, '_chat_completion', return_value=None): | |
| agent.chat("test prompt") | |
| # Verify that knowledge is now processed and available. | |
| assert agent.knowledge is not None | |
| assert agent._knowledge_processed is True |
| # With lazy loading, knowledge is None until first use | ||
| assert agent._knowledge_sources is not None | ||
| assert agent._knowledge_processed == False | ||
| # Trigger knowledge processing | ||
| agent._ensure_knowledge_processed() | ||
| assert agent.knowledge is not None |

Applying the same principle here as in my previous comment. Testing via the public API (chat()) instead of internal methods will make this test more resilient to future refactoring of the Agent class.
This tests the observable behavior (knowledge processing on first use) rather than the internal state, which is a more robust testing strategy.
| # With lazy loading, knowledge is None until first use | |
| assert agent._knowledge_sources is not None | |
| assert agent._knowledge_processed == False | |
| # Trigger knowledge processing | |
| agent._ensure_knowledge_processed() | |
| assert agent.knowledge is not None | |
| # With lazy loading, knowledge is None until first use. Test this initial state. | |
| assert agent.knowledge is None | |
| assert agent._knowledge_processed is False | |
| # Trigger knowledge processing via a public method, mocking the expensive part. | |
| with patch.object(agent, '_chat_completion', return_value=None): | |
| agent.chat("test prompt") | |
| # Verify that knowledge is now processed and available. | |
| assert agent.knowledge is not None | |
| assert agent._knowledge_processed is True |

Technical Details
The issue was that the tests were checking implementation details rather than actual behavior. The agent correctly uses lazy loading where
knowledgeisNoneuntil first access, which is an intentional performance optimization. The tests were incorrectly expecting immediate availability.This fix maintains the lazy loading performance benefits while ensuring the tests validate the correct behavior.
