Here is my unit test:

[Test]
[RollBack]
public void should_get_employee_inserted_message_when_the_employee_is_inserted()
{
MockRepository mocks = new MockRepository();
var mockedView = mocks.CreateMock<IAddEmployeeView>();


Expect.Call(mockedView.BarCode).Return("1111");
Expect.Call(mockedView.FirstName).Return("Mohammad");
Expect.Call(mockedView.LastName).Return("Azam");

mockedView.Message = "Employee inserted";

mocks.ReplayAll();

AddEmployeePresenter presenter = new AddEmployeePresenter(mockedView);
presenter.AddEmployee();
mocks.VerifyAll();

}

Here is the presenter (AddEmployee method):

public void AddEmployee()
{
//bool result = _repository.AddEmployee(
// new Employee()
// {
// BarCode = _view.BarCode,
// FirstName = _view.FirstName,
// LastName = _view.LastName,
// });

//if (result)
//{ _view.Message = "Employee inserted"; }
//else { _view.Message = "Employee not inserted"; }

Employee employee = new Employee()
{
BarCode = _view.BarCode,
FirstName = _view.FirstName,
LastName = _view.LastName
};



//employee.Save();

//if (employee.Id > 0)
//{
// _view.Message = "Employee inserted";
//}
//else { _view.Message = "Employee not inserted"; }
}


You will see that a lot of code has been commented out. I am more towards the repository approach since that is an interface and I can mock the behavior of the interface.
