Worked on the LabKey/platform repository to enhance the reliability and coverage of integration tests for cross-folder imports. Focused on backend development and integration testing using TypeScript, the work involved updating an existing test to accurately validate error handling when importing data with invalid entries. No production code was changed, ensuring that the risk to the live system remained minimal while improving the quality assurance process. The updated test now asserts the expected error message for cross-folder update scenarios, supporting safer future refactors. Documentation of these changes was included in the commit to facilitate future code reviews and maintainability.
