ASP MVC Test Assert "Expected<>" Unexpected

I'm trying to unit test my ASP MVC application, but my test fails with the message Message: Assert.AreEqua failed. Expected:<>. Actual: <Error>.

Now, I assume this is because I've set up the test wrong, but I can't find the place where I might have missed something. Any hints would be greatly appreciated. I'm using Moq.

My test class:

[TestClass]
public class ErrorControllerTest
{
    [TestMethod]
    public void TestErrorView()
    {
        var repositoryMock = new Mock<IErrorRepository>();
        var errors = new List<ErrorModel>();
        errors.Add(new ErrorModel()
        {
            Id = "id",
            Message = "message"
        });

        repositoryMock.Setup(r => r.GetErrors()).Returns(errors);
        var controller = new ErrorController(repositoryMock.Object);

        var result = (ViewResult) controller.Error(1);

        Assert.AreEqual(result.ViewName, "Error");
        repositoryMock.VerifyAll();
    }
}

For good measure, this is the controller under test:

public class ErrorController : Controller
{
    private readonly IErrorRepository errorRepository;

    public ErrorController(IErrorRepository errorRepository)
    {
        this.errorRepository = errorRepository;
    }

    public ActionResult Error(int? page)
    {
        var errors = errorRepository.GetErrors();

        //// stuff for paging
        int pageSize = 10;
        int pageNumber = (page ?? 1); // if there is no page, return page 1

        return View(errors.ToPagedList(pageNumber, pageSize));
    }
}

And the repository:

 public interface IErrorRepository
{
    List<ErrorModel> GetErrors();
}

public class ErrorRepository : IErrorRepository
{
    public ErrorModel Errors { get; set; }
    public List<ErrorModel> ErrorList { get; set; }

    public List<ErrorModel> GetErrors()
    {
        string cs = "Data Source=" + "some path";

        using (SQLiteConnection con = new SQLiteConnection(cs))
        {
            var listOfErrors = new List<ErrorModel>();
            string stm = "SELECT * FROM Error";
            con.Open();

            using (SQLiteCommand cmd = new SQLiteCommand(stm, con))
            {
                using (SQLiteDataReader rdr = cmd.ExecuteReader())
                {
                    while (rdr.Read())
                    {
                        listOfErrors.Add(new ErrorModel
                        {
                            Id = rdr["ID"].ToString(),
                            Message = rdr["Message"].ToString()
                        });
                    }

                    rdr.Close();
                    ErrorList = listOfErrors;
                }
            }

            con.Close();
        }

        return ErrorList;
    }
}
