Worked on enhancing the commercetools/test-data repository by developing new Inventory Entry test data presets that support multiple SKUs and warehouse combinations. Focused on migrating the underlying data model to enable broader and more realistic test scenarios, the work included refactoring existing presets to align with the updated structure for improved maintainability. Leveraged TypeScript and Jest to expand test data generation capabilities, which streamlined test setup and increased data consistency across different environments. The changes addressed the requirements of the FEC-88 migration, providing a more flexible foundation for future test data needs while maintaining a clear and organized codebase.
