In my test, I defined as data a List<IUser>
with some record in.
I'd like setup a moq the methode Update
, this method receive the user id
and the string
to update.
Then I get the the IUser
and update the property LastName
I tried this :
namespace Tests.UnitTests
{
[TestClass]
public class UsersTest
{
public IUsers MockUsersRepo;
readonly Mock<IUsers> _mockUserRepo = new Mock<IUsers>();
private List<IUser> _users = new List<IUser>();
[TestInitialize()]
public void MyTestInitialize()
{
_users = new List<IUser>
{
new User { Id = 1, Firsname = "A", Lastname = "AA", IsValid = true },
new User { Id = 1, Firsname = "B", Lastname = "BB", IsValid = true }
};
Mock<IAction> mockUserRepository = new Mock<IAction>();
_mockUserRepo.Setup(mr => mr.Update(It.IsAny<int>(), It.IsAny<string>()))
.Returns(???);
MockUsersRepo = _mockUserRepo.Object;
}
[TestMethod]
public void Update()
{
//Use the mock here
}
}
}
But I get this error : cannot resolve Returns symbole
Do you have an id ?
class User : IUser
{
public int Id { get; set; }
public string Firsname { get; set; }
public string Lastname { get; set; }
public bool IsValid { get; set; }
}
interface IUser
{
int Id { get; set; }
string Firsname { get; set; }
string Lastname { get; set; }
bool IsValid { get; set; }
}
interface IAction
{
List<IUser> GetList(bool isActive);
void Update(int id, string lastname)
}
class Action : IAction
{
public IUser GetById(int id)
{
//....
}
public void Update(int id, string lastname)
{
var userToUpdate = GetById(id);
userToUpdate.LastName = lastname;
//....
}
}
If you just want to verify this method is called, you should use Verifiable() method.
If you also want to do something with those parameters, use Callback() first.
Update
Here's how you should mock it if you return a bool value as result.
