Question

I am trying to unit test a simple factory, but it keeps telling me that I am trying to use a method like a type. What’s going on?

My unit test:

using System;
using System.Text;
using System.Collections.Generic;
using System.Linq;
using Microsoft.VisualStudio.TestTools.UnitTesting;
using Home;

namespace HomeTest
{
    [TestClass]
    public class TestFactory
    {
        [TestMethod]
        public void DoTestFactory()
        {
            InventoryType.InventorySelect select = new InventoryType.InventorySelect();
            select.inventoryTypes.Add("cds");

            Home.Services.Factory.CreateInventory get = new Home.Services.Factory.CreateInventory();
            get.InventoryImpl();

            if (select.Validate() == true)
                Console.WriteLine("Test Passed");
            else
                if (select.Validate() == false)
                    Console.WriteLine("Test Returned False");
                else
                    Console.WriteLine("Test Failed To Run");

            Console.ReadLine();

        }
    }
}

My factory:

using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;

namespace Home.Services
{
    public class Factory
    {
        public InventorySvc CreateInventory()
        {
            return new InventoryImpl();
        }

    }
}

You’re trying to create an instance of the method you’re calling and then calling the method that it was calling. Instead, create your factory and then call CreateInventory.

var factory = new Home.Services.Factory();
var inventory = factory.CreateInventory();

• I tend to avoid using select and get as variable names as they are keywords when used elsewhere.
