MS-Test in C# .net

Question

Hi Sir,
Hope you are doing well!
I need some help in MS-Unit testing in C# .net program, I watched all of your youtube videos but....
So,
Below is my question, Please help!
Write Automated MS-Unit Test in C#.NET for the following C#.NET program. The program converts a decimal value into binary? (10 Marks)

using System;
namespace BinaryClass
{
class Program
{
static void Main(string[] args)
{
Program p = new Program();
Console.WriteLine("Binary Value of 4 = "+p.IntToBinaryString(4));
}
public string IntToBinaryString(int number)
{
const int mask = 1;
var binary = string.Empty;
while (number > 0)
{
binary = (number & mask) + binary;
number = number >> 1;
}
return binary;
}
}
}

Answer 1

I would put the function you want to test in another class

using System;

namespace BinaryClass
{
     class Program
     {
          static void Main(string[] args)
          {
               Console.WriteLine("Hello World!");
              BinaryConverter p = new BinaryConverter();
              Console.WriteLine("Binary Value of 4 = " + p.IntToBinaryString(4));
         }


   }

   public class BinaryConverter
   {
        public string IntToBinaryString(int number)
       {
              const int mask = 1;
              var binary = string.Empty;
              while (number > 0)
              {
                  binary = (number & mask) + binary;
                  number = number >> 1;
              }
             return binary;
         }
     }
}

Then you can add a unit test project to the solution and add a reference to the binaryclass project

You can test what the function you expect the function to return against what is actually returned. You run the tests in the unit test window

public class UnitTest1
{
    [TestMethod]
    public void TestBinary4()
    {
        BinaryClass.BinaryConverter p = new BinaryClass.BinaryConverter();
        string expected = "100";
        string actual = p.IntToBinaryString(4);

        Assert.AreEqual(expected,actual);
    }
}

This looks like a homework assignment or test question. Asking for others to answer the question for you is cheating.
