Stored Procedure Testing using Nunit

In this post we will look at stored procedure testing using Nunit. We will be

• Reusing stored procedure created for SSRS report link
• Create Table Earnings and procedure SaleCity
• Earlier we looked into TST codeplex tool

This example is In continuation with previous Nunit post. Stored Proc test approach I learnt from book Expert SQL Server 2008 Development.

Step 1 - Created VS 2008 Class Library

Step 2 - Added Reference to  DLL nunit.framework.dll in the project

Step 3 - Copy below code in the Class1.cs file

using System;

using System.Collections.Generic;

using System.Linq;

using System.Text;

using System.Data;

using System.Data.SqlClient;

using NUnit.Framework;

namespace ClassLibrary1

{

    [TestFixture]

    public class Class1

    {

        [Test]

        public void TestSaleCity()

        {

            // Set up a command object

            SqlCommand comm = new SqlCommand();

            // Set up the connection

            comm.Connection = new SqlConnection(

            @"server=.\SQLExpress; trusted_connection=true; database=AppDB");

            // Specify Procedure Name

            comm.CommandText = "dbo.SaleCity";

            comm.CommandType = CommandType.StoredProcedure;

            comm.Parameters.AddWithValue("@City", "Chennai");

            // Create a DataSet for storing the results

            DataSet ds = new DataSet();

            // Define a DataAdapter to fill a DataSet

            SqlDataAdapter adapter = new SqlDataAdapter();

            adapter.SelectCommand = comm;

            try

            {

                // Fill the dataset

                adapter.Fill(ds);

            }

            catch

            {

                Assert.Fail("Exception occurred!");

            }

            // Validate Actual Results

            Assert.IsTrue(ds.Tables.Count == 1,

            "Result set count != 1");

            DataTable dt = ds.Tables[0];

            // There must be exactly four columns returned

            Assert.IsTrue(

            dt.Columns.Count == 4,

            "Column count != 4");

            // There must be columns City, SaleValue, SaleDate and Name

            Assert.IsTrue(

            dt.Columns.IndexOf("City") > -1,

            "Column City does not exist");

            Assert.IsTrue(

            dt.Columns.IndexOf("SaleValue") > -1,

            "Column SaleValue does not exist");

           

            Assert.IsTrue(

            dt.Columns.IndexOf("SaleDate") > -1,

            "Column SaleDate does not exist");

           

            Assert.IsTrue(

            dt.Columns.IndexOf("Name") > -1,

            "Column Name does not exist");

            // There must be more than one row returned

            Assert.IsTrue(

            dt.Rows.Count >= 1,

            "Result rows returned");

        }

    }

}

Step 4 - Build the Project

Step 5 - Using Nunit Open the Debug folder, You will see ClassLibrary1 DLL. Below is the snapshot of results

.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
