Question

I am a newbie to unit testing. How do I check the for console output? I have

namespace XXShapes
{
    public abstract class XXShape
    {
        public virt         


        

Answer 1

The literal answer would be that you would use Console.SetOut before calling the class under test to direct stdout into a memoryStream or similar, whose contents you can later inspect.

The better answer would be to use a mocking framework, like Rhino Mocks to create a concrete instance of your abstract class, with an expectation set that the DrawXXShape method would be called.
