Why is the class not accessible in unit test?

Question

I have created a unit test for a method in a class called game.cs. For some reason, when I reference the class, I am unable to create a new instance. How do I make this class accessible so I can test my code?

File Hierarchy and solution:

using System;
using Microsoft.VisualStudio.TestTools.UnitTesting;
using BowlingKataTDD;

namespace BowlingKataTDDTest
{
    [TestClass]
    public class BowlingKataTDDUnitTests 
    {
        [TestMethod]
        public void DoesGameExist()
        {
            //arrange
            BowlingKataTDD.
        }
    }
}

BowlingKataTDD Project:

using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using System.Threading.Tasks;

namespace BowlingKataTDD
{
    class Game
    {
        static void Main(string[] args)
        {
        }
    }
}

Answer 1

The reason you do not see the classes is that they are non-public (internal by default).

There are two solutions to this:

• If you would like to make your classes visible to outside users, make them public
• If you would rather not publish your classes, use InternalsVisibleTo attribute.

To use the second solution, open AssemblyInfo.cs and add the following line:

[assembly: InternalsVisibleTo("BowlingKataTDDTest")]

BowlingKataTDDTest is the name of your assembly, as defined in the project file.
