During July 2025, work centered on enhancing the labd/commercetools-node-mock repository by implementing comprehensive Business Unit Address Management features. This involved developing new API actions to set a default shipping address, add shipping address IDs, and remove addresses within business units, all using TypeScript and Node.js. The approach focused on action-based API design, which improved code maintainability and clarity. By increasing the fidelity of billing and shipping address workflows in the mock environment, the updates enabled more reliable integration testing. No major bugs were addressed during this period, as the primary contribution was the delivery of robust, realistic feature enhancements.
