When running Litium during integration testing of stand-alone add-ons, I need to implement the following abstract classes, even though I'm not using ERP Connect API:
- AdditionalInfoProductService
- InventoryService
- OrderService
- PriceListService
- RmaService
- ShippingService
It seems kind of silly that I need to create 6 empty classes just to get Litium to start up. Historically, these kind of services has always been provided with a default fallback service in the product itself.
