带有构造函数注入的单元测试ASP.NET MVC控制器

Question

How do i setup my test project so that i can unit test my controllers, I'm not able to call my controller actions from test method as it requires dependent interface object. I don't want to implement any mock repository. I want to use my existing database repository and business logic available same as integration testing.

My Project Structure is as below:

• MVC.Web
• MVC.BL (Interface and implementation)
• MVC.Repository (Interface and implementation)

Repository Example:

public class UserRepository : IUserRepository
{
    private readonly IBaseUOW<DBEntitiesEntities> _dbContext;
    private readonly IBaseRepository<User> _userRepository;

    public UserRepository(IBaseUOW<MoynoECTNewEntities> dbContext)
    {
        _dbContext = dbContext;
        _userRepository = dbContext.GetRepository<User>();
    }

    public UserResponse GetUserList()
    {
        var response = new UserResponse {Acknowledge = AcknowledgeType.Success};

        var typeList = _userRepository.Get().OrderBy(x => x.UserName).ToList();

        response.UserList = typeList.ToList();

        return response;
    }
}

Business Layer Example:

public class UserBL : IUserBL
{
    public UserResponse GetUserList()
    {
        var response = new UserResponse();

        var userList = _userRepository.GetUserList();
        if (userList != null && userList.UserList.Count > 0)
        {
            response.UserList = userList.UserList.ToList();
        }
        else
        {
            response.Message = "No Data Found";
            response.Acknowledge = AcknowledgeType.Failure;
        }

        return response;
    }
}

Controller Example:

public class AdminController : BaseController
{
    public readonly IUserBL _userBl;
    public readonly IUserRoleBL _userRoleBl;

    public AdminController(IUserRoleBL userRoleBl, IUserBL userBl)
    {
        _userRoleBl = userRoleBl;
        _userBl = userBl;
    }

    public ActionResult GetUserList()
    {
        var response = _userBl.GetUserList();
        return View("_GridViewUser", response.UserList);
    }
}

My unit test method example:

[TestClass]
public class AdminControllerTest
{

    [TestMethod]
    public void Check_UserMaster_ViewName()
    {
       //assemple
        var controller = // how to call controller ?
       // act
        var result= // controller.GetUserList() as ViewResult;
       // assert
        Assert.AreEqual("UserMaster", result.ViewName);
    }
}

Answer 1

I don't want to implement mock repository and directly want to use my existing database repository

Well I think that's the wrong approach since you're unit testing the class, meaning all dependencies should not impact the validity of the test, but that's your call.

Just pass in an instance of the "real" repository in your test.

var userRoleBL = new UserBL();
var userBL = new UserRoleBL();
var controller = new AdminController(userRoleBL, userBL);
// test the controller

Answer 2

As @D Stanley said, you should only test that the Controller returns the appropriate result, not that the other layers, database etc. are working.

However, to create the Controller in a Unit Test use:

var controller = new AdminController(any arguments/contexts here);
