Nunit test

Hello,
I need to write a nunit test for this bit of code:

using System;
using System.Linq;

namespace EE_Q29143059
{
    class Program
    {
        static void Main(string[] args)
        {
            var data = "1,0,0,1";
            var result = $"?{String.Join("&", data.Split(new[] { "," }, StringSplitOptions.RemoveEmptyEntries).Select(x => $"message={x}"))}";
            Console.WriteLine(result);
            Console.ReadLine();
        }
    }
}

Thanks
