问题描述

我成功地基于简单的成员数据库，在MVC 5(实体框架6应用程序)中使用MOC与MOQ对我的BustAct控制器进行模拟的集成测试.但是现在我已经将数据库迁移到Identity 2.0，并用ApplicationSer替换了UserProfile.

IdentityDbContext :(从简单的成员资格DBContext修改)

public class MyDb : IdentityDbContext<ApplicationUser> // DbContext  
  {
    public MyDb () : base("MyApplication") { }

    // public virtual DbSet<UserProfile> UserProfiles { get; set; }
    public virtual DbSet<BusAcnt> BusAcnts { get; set; } // marking as virtual allows mocking override
    public virtual DbSet<...>
    ...

    protected override void OnModelCreating(DbModelBuilder modelBuilder)
    {
      base.OnModelCreating(modelBuilder);
      modelBuilder.Conventions.Remove<PluralizingTableNameConvention>();
    }
  }

Mockdbsetup:

public class MockDbSetup
  {
    public static Mock<MyDb> MockMyDb()
    {
      var dataBa = new List<BusAcnt>  {
        new BusAcnt {Id = 0, CmpnyName = "Company 1", NmOfc = 1, Status = "Active"},
        new BusAcnt {Id = 1, CmpnyName = "Company 2", NmOfc = 1, Status = "Active"},
        new BusAcnt {Id = 2, CmpnyName = "Company 3", NmOfc = 1, Status = "Active"},
        new BusAcnt {Id = 3, CmpnyName = "Company 4", NmOfc = 1, Status = "Active"},
        new BusAcnt {Id = 4, CmpnyName = "Company 5", NmOfc = 1, Status = "Active"},
        new BusAcnt {Id = 5, CmpnyName = "Company 6", NmOfc = 1, Status = "Active"}
      }.AsQueryable();
      var mockSetBa = new Mock<DbSet<BusAcnt>>();
      mockSetBa.As<IQueryable<BusAcnt>>().Setup(m => m.Provider).Returns(dataBa.Provider);
      mockSetBa.As<IQueryable<BusAcnt>>().Setup(m => m.Expression).Returns(dataBa.Expression);
      mockSetBa.As<IQueryable<BusAcnt>>().Setup(m => m.ElementType).Returns(dataBa.ElementType);
      mockSetBa.As<IQueryable<BusAcnt>>().Setup(m => m.GetEnumerator()).Returns(dataBa.GetEnumerator());
      var MyDb = new Mock<MyDb>();
      mockMyDb.Setup(c => c.BusAcnts).Returns(mockSetBa.Object);
      return mockMyDb;
    }
  }

集成测试:

[Fact]
public void GetAllBusAcnt()
{
  var mockMyDb = MockDBSetup.MockMyDb();
  var controller = new BusAcntController(mockMyDb.Object);
  var controllerContextMock = new Mock<ControllerContext>();
  controllerContextMock.Setup(
      x => x.HttpContext.User.IsInRole(It.Is<string>(s => s.Equals("admin")))
      ).Returns(true);
  controller.ControllerContext = controllerContextMock.Object;

  var viewResult = controller.Index() as ViewResult;
  var model = viewResult.Model as PagedBusIdxModel;

  Assert.NotNull(model);
  Assert.Equal(6, model.BusAcnts.ToList().Count());
  Assert.Equal("Company 2", model.BusAcnts.ToList()[1].CmpnyName);
}

现在进行测试时，我会得到这些错误:

System.Data.Entity.ModelConfiguration.ModelValidationExceptionOne or more validation errors were detected during model generation:

Castle.Proxies.IdentityUserRole: : EntityType 'IdentityUserRole' has no key defined. Define the key for this EntityType.

   at Castle.Proxies.MyDbProxy..ctor(IInterceptor[])

我相信我需要修改Mockdbsetup，但无法找到有关如何做到这一点的任何信息.

我尝试添加

var dataUsr = new List<ApplicationUser>
  {
    new ApplicationUser { UserName = "Test", PasswordHash = "a123cdefg"} }.AsQueryable();
  var mockSetUsr = new Mock<DbSet<ApplicationUser>>();
  mockSetUsr.As<IQueryable<BusAcnt>>().Setup(m => m.Provider).Returns(dataUsr.Provider);
  mockSetUsr.As<IQueryable<BusAcnt>>().Setup(m => m.Expression).Returns(dataUsr.Expression);
  mockSetUsr.As<IQueryable<BusAcnt>>().Setup(m => m.ElementType).Returns(dataUsr.ElementType);
  mockSetUsr.As<IQueryable<BusAcnt>>().Setup(m => m.GetEnumerator()).Returns(dataUsr.GetEnumerator());

，但我在GetEnumerator

上得到了”无法解决”错误

，都不是

mockMyDb.Setup(c => c.AspNetUsers).Returns(mockSetUsr.Object);

或

mockMyDb.Setup(c => c.ApplicationUser).Returns(mockSetUsr.Object);

工作是因为它无法解析AspNetUsers或ApplicationUser.

有人对如何执行此操作有任何想法，链接到嘲笑身份2.0数据库的文档会特别有用吗?

推荐答案

感谢Jamie和Andreas’的答案，请测试框架说，实体没有为内置实体定义的密钥.

在MockMyDb()中MockDbSetup中的方法添加{ CallBase = true };到var MyDb = new Mock<MyDb>();中，导致

var MyDb = new Mock<MyDb>() { CallBase = true };

其他推荐答案

虽然可能有一种方法可以使EF绕过它的内部行为是为了嘲笑的目的，但迄今为止，最简单的方法是使用IDBSET代替DBSET，并从MyDB实例中提取一个接口./p>

public interface IMyDb   
{
    IDbSet<BusAcnt> BusAcnts { get; set; } // marking as virtual allows mocking override
    IDbSet<...>

    int SaveChanges();
}

您当前正在做的是一个部分模型，我一直发现这是有问题的.我只是避开它.
