Xuan Qi enhanced the Milvus collection schema by developing comprehensive test coverage for the add-field feature in the milvus-io/milvus repository. Using Python and the Milvus API, Xuan refactored the existing test suite to improve maintainability and introduced new unit tests focused on field addition scenarios. The work included updating response validations to assert field-level correctness across a range of cases, thereby increasing the robustness of the test suite. This effort addressed the need for safer schema evolution by reducing user risk during field additions and contributed to more reliable continuous integration outcomes for the Milvus project’s ongoing development.
