Faking inventory while waiting for integrations to finalize

In many Commerce projects there will be dependent activities running in parallel. You might be waiting for a warehouse inventory service to be developed while the shopping experience is developed. To prevent a delay in progress on the site without manually adding inventory in Commerce Manager, you can fake the implementation of IWarehouseInventoryService. 

Implement a fake stock in the Catalog

Fake implementation

    public class FakeWarehouseInventory : IWarehouseInventoryService

        private IWarehouseInventory GetFakeInventory(CatalogKey catalogKey)
            return GetFakeInventory(catalogKey, new Warehouse() {Code = "Default"});

        private IWarehouseInventory GetFakeInventory(CatalogKey catalogKey, IWarehouse warehouse)
           return new WarehouseInventory()
                AllowBackorder = true,
                AllowPreorder = true,
                BackorderAvailabilityDate = DateTime.Now.AddDays(-1),
                BackorderQuantity = 0,
                CatalogKey = catalogKey,
                InStockQuantity = 100,
                InventoryStatus = InventoryTrackingStatus.Enabled,
                PreorderAvailabilityDate = DateTime.Now.AddDays(5),
                PreorderQuantity = 0,
                ReorderMinQuantity = 0,
                ReservedQuantity = 0,
                WarehouseCode = warehouse.Code

        public IWarehouseInventory Get(CatalogKey catalogKey, IWarehouse warehouse)
            return GetFakeInventory(catalogKey, warehouse);
        public IEnumerable<IWarehouseInventory> List(IEnumerable<CatalogKey> catalogKeys)
            return catalogKeys.Select(GetFakeInventory) ;

        public IEnumerable<IWarehouseInventory> ListTotals(IEnumerable<CatalogKey> catalogKeys)
            return catalogKeys.Select(GetFakeInventory);


Use an initializable module to override the default WarehouseInventoryService

    public class InitializationModule : IConfigurableModule
        public void Initialize(EPiServer.Framework.Initialization.InitializationEngine context)
            CatalogRouteHelper.MapDefaultHierarchialRouter(RouteTable.Routes, false);            

        public void ConfigureContainer(ServiceConfigurationContext context)
             context.Container.Configure(ce => ce.For<IWarehouseInventoryService>().Use<FakeWarehouseInventory>());

        public void Preload(string[] parameters)

        public void Uninitialize(EPiServer.Framework.Initialization.InitializationEngine context)

Download FakeWarehouseInventory.cs

Of course, this approach will not work when you are testing features like tracking stock during purchases.

Creating a purchase order

In order to create a purchase order and make the workflows perform correctly with the fake data, you need to create your own fake implementation of IInventoryService.

Download a FakeInventoryService.cs.

Really good solution. You also can add some switch in appSettings and read it at configuration time to be able to switch between real service and fake one.
