Nunit test error

Question

Hi,

 

I have created very small program for Nunit.

while running test, getting some unexpected error. but build is successful.

 

I am not able to resolve this small problem. Could you please suggest where i am wrong.

using System;
using NUnit.Framework;
using OpenQA.Selenium;
using OpenQA.Selenium.Chrome;
using WebEx;

namespace Web_Utils
{
    [TestFixture]
    public class Program
    {
        static void Main(string[] args)
        {
        }
        [Test]
        public void Open()
        {
            Console.WriteLine("hello");
        }
    }
}
