test: Improve test coverage in various classes
- Add edge case tests for MimeTypeDetector and CoherenceFilterExpressionConverter - Add test for numeric comparison with category field - Tests CoherenceFilterExpressionConverter handling of greater-than-or-equal - Add comprehensive test coverage for QdrantObjectFactory and QdrantVectorStore.Builder - Add test for QdrantVectorStoreBuilderTests - Add comprehensive test coverage for QdrantObjectFactory and QdrantVectorStore.Builder. - Add comprehensive test coverage for QuestionAnswerAdvisor and VectorStoreChatMemoryAdvisor - Add comprehensive media content tests for MessageTypeContentTests - Addcomprehensive test coverage for various media content scenarios in chat message handling, focusing on edge cases and mixed content types. - Add comprehensive test coverage for DefaultChatClient and DefaultChatClientBuilder - Add comprehensive edge case tests for Ollama embedding and chat models - Add comprehensive test coverage for edge cases and boundary conditions in Ollama model implementations: Co-authored-by: Oleksandr Klymenko <[email protected]> Signed-off-by: Oleksandr Klymenko <[email protected]>
