InventoryCommandFactoryTests

InventoryCommandFactoryTests contains unit tests related to InventoryCommandFactory. Because each test will have a similar pattern of constructing InventoryCommandFactory and its IUserInterface dependency and then running the GetCommand method, a shared method is created that will run when the test initializes:

[TestInitialize]public void Initialize(){    var expectedInterface = new Helpers.TestUserInterface(        new List<Tuple<string, string>>(),        new List<string>(),        new List<string>()    );     Factory = new InventoryCommandFactory(expectedInterface);}

The Initialize method constructs a stubbed IUserInterface and sets the Factory property. The individual unit tests then take a simple form of validating that the object returned ...
