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
    public class Class1
        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;
                // Fill the dataset

                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
            dt.Columns.Count == 4,
            "Column count != 4");

            // There must be columns City, SaleValue, SaleDate and Name
            dt.Columns.IndexOf("City") > -1,
            "Column City does not exist");

            dt.Columns.IndexOf("SaleValue") > -1,
            "Column SaleValue does not exist");
            dt.Columns.IndexOf("SaleDate") > -1,
            "Column SaleDate does not exist");
            dt.Columns.IndexOf("Name") > -1,
            "Column Name does not exist");

            // There must be more than one row returned
            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
