.NET API Testing - Part II - Nunit Tests

In continuation with previous post we are now going to write Nunit Tests for earlier post.
1. Downloaded Nunit from link
2. Created a Test Project in VS 2008
3. Add Reference to DLL nunit.framework.dll in the project
4. Copy below modifed code in UnitTest1.cs

public class TestDesign

{

    public int SumofTwoNumbers(int InputA, int InputB)

    {

        return (InputA + InputB);

    }

}

namespace APITest

{

    using NUnit.Framework;

    [TestFixture]

    public class TestExample

    {

        [Test]

        //Test Method

        public void TestAddAPI()

        {

            TestDesign TD = new TestDesign();

            Assert.AreEqual(30,TD.SumofTwoNumbers(10, 20));

            Assert.AreEqual(33, TD.SumofTwoNumbers(10, 23));

        }

        //Data Driven Testing

        [TestCase(10, 10, Result=20)]

        [TestCase(15, 15, Result=30)]

        [TestCase(20, 20, Result=40)]

        public int TestAddAPI(int a, int b)

        {

            TestDesign TD = new TestDesign();

            return TD.SumofTwoNumbers(a, b);

        }

    }

}

5. Build the Project
6. Using Nunit Open the Debug folder, You will see Test Project DLL. Below is the snapshot of results
