NUnit Testing

Question

Hello All,

I am supposed to write NUnit Test Cases for the below method. Can anyone tell me how do I assign a value for the below scenario?

 [Test]

        public void method_Test()

        {

Animal animal = null;    //how to assign the value?    

bool isHerbivore = false;

CategorizeAnimal ca  = new CategorizeAnimal(animal,isHerbivore); // TODO: Initialize to an appropriate value

        int expected = 0; // TODO: Initialize to an appropriate value

        int actual;

        actual = ca.getProcedureDuration();

         NUnit.Framework.Assert.AreEqual(expected, actual);

         NUnit.Framework.Assert.Inconclusive("Verify the correctness of this test method.");

        }

public class Animal

{

[DataMember]

public int numOfLegs;

[DataMember]

public EnumValue color;

}

The question is:

How do I assign a value for the object animal?

Please Help :)
