If you use the default settings of Microsoft Visual Studio 2008/2010 UnitTesting, the Console.WriteLine and Debug.WriteLine won’t be shown. By double clicking the test, you can see the test details, including the standard output and debug output, but I wanted to see the messages directly after a run. This can be done by right clicking de gridview in the Test Results window and adding the columns Output (StdOut) and Debug Trace.

UnitTest class

using System;
using System.Text;
using System.Collections.Generic;
using System.Linq;
using Microsoft.VisualStudio.TestTools.UnitTesting;

namespace Scripts
{
    [TestClass]
    public class MainUnitTest
    {
        [TestMethod]
        public void TestMethod1()
        {
            string result = string.Empty;

            result = "This is some debug output";
            System.Diagnostics.Debug.WriteLine(result);

            result = "This is some standard console output";
            System.Console.WriteLine(result);
        }
    }
}
