Moq單元測試按產品類別過濾產品

Question

我是單元測試新手，所以我確信這是一個非常基本的問題，但是當我搜索它時找不到解決方案。

我正在測試以查看是否可以按其類別過濾產品。我可以訪問我的Product類中的所有屬性，但不能訪問我的Category類中的所有屬性。例如，它找不到Category1.Name。誰能告訴我我做錯了什麼？

這是我的產品類;

public partial class Product 
    { 
     public int ProductID { get; set; } 
     public string Name { get; set; } 
     public string Description { get; set; } 
     public decimal Price { get; set; } 
     public int CategoryID { get; set; } 

     public virtual Category Category1 { get; set; } 
    } 

這是我的測試;

[TestMethod] 
     public void Can_Filter_Products() 
     { 
      //Arrange 

      Mock<IProductRepository> mock = new Mock<IProductRepository>(); 
      mock.Setup(m => m.Products).Returns(new Product[] 
      { 
       new Product {ProductID=1,Name="P1", **Category1.Name** = "test1" }, 
       new Product {ProductID=2,Name="P2", **Category1.Name** = "test2"}, 
       new Product {ProductID=3,Name="P3", **Category1.Name** = "test1"}, 
       new Product {ProductID=4,Name="P4", **Category1.Name** = "test2"}, 
       new Product {ProductID=5,Name="P5", **Category1.Name** = "test3"}, 
      }.AsQueryable()); 

      //Arrange create a controller and make the page size 3 items 
      ProductController controller = new ProductController(mock.Object); 
      controller.PageSize = 3; 

      //Action 
      Product[] result = ((ProductsListViewModel)controller.List("test2", 1).Model).Products.ToArray(); 

      //Assert - check that the results are the right objects and in the right order. 
      Assert.AreEqual(result.Length, 2); 
      Assert.IsTrue(result[0].Name == "P2" && result[0].Category1.Name == "test2"); 
      Assert.IsTrue(result[1].Name == "P4" && result[1].Category1.Name == "test2"); 
     }

在你的模擬設置，試試這個來代替：

 mock.Setup(m => m.Products).Returns(new[] 
     { 
      new Product {ProductID=1,Name="P1", Category1 = new Category { Name = "test1"} }, 
      new Product {ProductID=2,Name="P2", Category1 = new Category { Name = "test1"} } 
     }.AsQueryable());
