我试图为控制器编写单元测试以测试方法返回所有用户。但我很困惑如何用automapper编写单元测试
控制器:
private readonly IUserService _userService;
public UserController(IUserService userService)
{
this._userService = userService;
}
public ActionResult List()
{
var users = _userService.GetAllUsers().ToList();
var viewModel = Mapper.Map<List<UserViewModel>>(users);
return View(viewModel);
}
控制器测试:
private Mock<IUserService> _userServiceMock;
UserController objUserController;
List<UserViewModel> listUser;
[SetUp]
public void Initialize()
{
_userServiceMock = new Mock<IUserService>();
objUserController = new UserController(_userServiceMock.Object);
listUser = new List<UserViewModel>()
{
new UserViewModel() {Id = 1, Active = true, Password = "123456", UserName = "hercules"},
new UserViewModel() {Id = 2, Active = false, Password = "1234567", UserName = "alibaba"},
new UserViewModel() {Id = 3, Active = true, Password = "12345678", UserName = "robinhood"},
};
}
[Test]
public void Index_Returns_AllUser()
{
// How do I here ???
}

像在MVC项目中一样配置automapper:
[SetUp]
public void Initialize()
{
....
AutoMapperConfiguration.Configure();
}
AutoMapperConfiguration是一个公共静态类,如:
public class AutoMapperConfiguration
{
/// <summary>
/// Maps between VIEWMODEL and MODEL
/// </summary>
public static void Configure()
{
//maps here
Mapper.CreateMap..
}
}

您可以使用接口为automapper创建包装类。例如:
public interface IMapperWrapper
{
object Map(object source, Type sourceType, Type destinationType);
}
然后你在测试中需要做的只是嘲笑你的地图。
automapperWrapperMock.Setup(x => x.Map, type, type);

你正在尝试编写一个几乎没有价值的测试。不要写这个测试。使用真正的IUserService并使用真正的AutoMapper并对ViewResult进行断言。
我永远不会对这段代码进行单元测试。
但如果您完全不愿意编写此单元测试,请不要模拟AutoMapper。模拟IUserService。
UserController objUserController;
List<User> listUser;
[SetUp]
public void Initialize()
{
var userServiceMock = new Mock<IUserService>();
listUser = new List<User>()
{
new User() {Id = 1, Active = true, Password = "123456", UserName = "hercules"},
new User() {Id = 2, Active = false, Password = "1234567", UserName = "alibaba"},
new User() {Id = 3, Active = true, Password = "12345678", UserName = "robinhood"},
};
userServiceMock.Setup(framework => framework.GetAllUsers())
.Returns(listUser);
objUserController = new UserController(_userServiceMock.Object);
}
[Test]
public void Index_Returns_AllUser()
{
var result = objUserController.List();
var viewResult = result as ViewResult;
viewResult.ShouldNotBe(null);
var model = viewResult.Model as List<UserListModel>;
model.ShouldNotBe(null);
model.Count.ShouldBe(3); // Don't do more than this
}

只需设置控制器调用Automapper配置,该控制器的所有测试都将正常运行。
