Unable to get Default Constructor

I an getting the below issue when running the Unit Test project.

Unable to get Default Constructor For class ********

[TestClass]
public class PersonRegistration
{
    private ILoggingService _loggingService;
    private IUserManager _userManager;
    public PersonRegistration(IUserManager userManager, ILoggingService loggingService)
    {
        this._userManager = userManager;
        this._loggingService = loggingService;
    }
    [TestMethod]
    public void TestMethod1()
    {
        RegisterBindingModel model = new RegisterBindingModel();
        AccountController ac = new AccountController(_userManager, _loggingService);
        model.UserName = "test123@gmail.com";
        var result = ac.Register(model);
        Assert.AreEqual("User Registered Successfully", result);
    }

How to fix that. Some answers says that to use a parameter less constructor. But here I need params.

RegisterBindingModel()

public class RegisterBindingModel
{
    public RegisterBindingModel();
    [Display(Name = "User name")]
    [Required]
    public string UserName { get; set; }
}
