Database Testing Checklist

Database Testing

  • Synchronization between the database and the values displayed in our client/web.
  • Query results, views, stored procedures, indexers Etc.
  • Data manipulation (Update, Delete, insert Etc.).
  • Database performance.
  • Data maintenance.
  • Table’s structure.
  • Data recovery.
  • Data integrity.
  • Others

Clean database testing

  • Verify clean database testing.
  • Input 1st data

Database system-level tests

  • Validate the DB behavior of any case of service failures (recovery, error handling Etc.).
  • Validate that all indexes are created when it can increase the system performance.
  • Validate that appropriate events are created ad sent to the EventVwr/trace log.
  • Validate that DB tables are created with informative and reasonable names.
  • Try to work when the storage is ‘0’ and the e database is in running state.
  • Perform your tests on different versions (SQL 2005, 2008, 2012 etc.).
  • Validate the software security model (User roles, permissions etc.).
  • Validate the connection strings against SQL/Win authentications.
  • Validate data migrations (Different Database, Cluster, etc.).
  • Validate the behavior of the system against SQL injections.
  • Validate date to DB when the server is loaded.
  • Try to work when the database server is down.
  • Try to work with difference instance.
  • Validate restore and backup plans.

Database Integration Testing

  • Check that all columns are set with the relevant data type (Bigint, int, string Etc.)
  • Check that all data is logically organized in the relevant DB tables.
  • Check that each data item is located under the relevant column.
  • Is there any irrelevant data in the software dedicated tables?
  • Check that each table contains the relevant data.
  • Try to insert invalid database values.
  • Verify the data encryption (if any).

Data field tests

  • Validate that “Allow Null” condition is not allowed in a place that result a software failure.
  • Validate that all tables are created with logical structure (Primary, foreign keys.)
  • Validate that “Allow Null” condition is set when you need to allow it.
  • Validate that mandatory fields are created, this issue is very important when you work with multiple tables that depends on each other.

Procedure tests

  • Validate that the data the affected by the procedure is changed as expected.
  • Validate that all procedures are triggered when they supposed to run.
  • Validate that all the conditions receive an appropriate date inputs.
  • Validate that all procedures are created with the relevant code.
  • Is there an appropriate error handling for a failed procedure?
  • Validate that all the loops receive an appropriate date inputs.
  • Validate the procedure’s parameters (types, names, etc.).
  • Test the SP while executing the code manually.
  • Validate important code with SQL profiler.
  • Validate that all procedures names
  • Run tests with missing parameters.

Database and software integration (Client, web Etc.)

  • Validate that the user data is saved when the user “Apply” or “Submit” the changes.
  • Try to insert “NULL” values on fields that doesn’t supposed to receive it.
  • Validate that the user receives the current result when pulling data.
  • Validate that transaction the data type boundaries (Minima Etc.)
  • Validate that empty spaces are not committed to the database.
  • Validate that the values displayed based on the database data.
  • Try to insert UNICODE on Unicode character strings.
  • Try to insert values that exceed the field boundaries.
  • Validate that transactions the negative data values.
  • Insert invalid date format on Date and time fields.
  • Validate that the data integrity is not affected when the “Apply” or “Submit transactions are failing during the process.
  • Validate that the “Roll Back” option is available when the DB transaction is failed in the middle.

Data checking

  • Create Data from frontend and check by Query
  • Delete Data from frontend and check by Query

When search value in all tables under a database

If someone wants to search by specific value in database, it’s difficult to search a value whole database. Below code easy way to find out

DECLARE @SearchStr nvarchar(100)
SET @SearchStr = ''
CREATE TABLE #Output (TableLocation nvarchar(370), Details_Information nvarchar(3630))
DECLARE @SearchTableName nvarchar(256), @ColumnName nvarchar(128), @SearchStr2 nvarchar(110)
SET  @SearchTableName = ''
SET @SearchStr2 = QUOTENAME('%' + @SearchStr + '%','''')
WHILE @SearchTableName IS NOT NULL
    SET @ColumnName = ''
    SET @SearchTableName = 
        WHERE         TABLE_TYPE = 'BASE TABLE'
            AND    QUOTENAME(TABLE_SCHEMA) + '.' + QUOTENAME(TABLE_NAME) > @SearchTableName
            AND    OBJECTPROPERTY(
                        QUOTENAME(TABLE_SCHEMA) + '.' + QUOTENAME(TABLE_NAME)
                         ), 'IsMSShipped'
                           ) = 0
    WHILE (@SearchTableName IS NOT NULL) AND (@ColumnName IS NOT NULL)
        SET @ColumnName =
            WHERE         TABLE_SCHEMA    = PARSENAME(@SearchTableName, 2)
                AND    TABLE_NAME    = PARSENAME(@SearchTableName, 1)
                AND    DATA_TYPE IN ('char', 'varchar', 'nchar', 'nvarchar', 'int', 'decimal')
                AND    QUOTENAME(COLUMN_NAME) > @ColumnName
        IF @ColumnName IS NOT NULL
            INSERT INTO #Output
                'SELECT ''' + @SearchTableName + '.' + @ColumnName + ''', LEFT(' + @ColumnName + ', 3630) FROM ' + @SearchTableName + ' (NOLOCK) ' +
                ' WHERE ' + @ColumnName + ' LIKE ' + @SearchStr2
SELECT TableLocation, Details_Information FROM #Output

how to get restore history in sql server

SELECT [rs].[destination_database_name],

Database to Single-user Mode in MS SQL Server 2008

Today I will discussed about, how to restrict access to single user.

Why need restrict access database?

* Single-user mode specifies that only one user at a time can access the database and is generally used for maintenance actions.

* When multiple users are connected to the database at the time that you set the database to single-user mode, their connections to the database will be closed without warning.

How to setup database to single user mode.

Step 1: Go to Start menu > All Programs > Microsoft SQL Server 2008 > SQL Server Management Studio and Connect to database server








Step 2: Right-click the database and click Properties.

Step 3:  In Database Properties dialog box, click Options page from left menu.

Step 4: Select SINGLE_USER  from the Restrict Access option

Step 5: If other users are connected to the database, an Open Connections message will appear. To change the property and close all other connections, click Yes.

How to setup selenium WebDriver with Nunit and Visual Studio (C#)

Selenium is an open source software tools which supporting tests automation. Now days, Software automation tools are becoming popular. Software automation tools are a time efficient. You will find different kinds of software automation tools, such as Load Runner, QTP, MS Test Manager, Jmeter etc. Selenium webdriver is a one of them. It is most popular automation tools.


Today, I am going to discussed about how to run selenium WebDriver with Nunit and Visual Studio (C#)


  • Download Nunit ( and install in your system
  • Download selenium web-driver (
  • Open a new project and Create a Class Library
  • Add reference webdriver dll (selenium-dotnet-2.35.0 > net40) and nunit dll (Where you installed).

Webdriver dll

Nunit Dll

Or you can add Nunit dll from assemblies > Extension

  • When all of this is done and you can start write a code

Point 1:

using System;

using System.Collections.Generic;

using System.Linq;

using System.Text;

using System.Threading.Tasks;

using NUnit.Framework;

using OpenQA.Selenium;

using OpenQA.Selenium.Firefox;

using OpenQA.Selenium.Internal;

using OpenQA.Selenium.Support.UI;


Point 2:

namespace Automation

public class framework
private IWebDriver driver;

public void LoadDriver()
Console.WriteLine("Check SetUp");
driver = new FirefoxDriver();
// To Maximise browser

public void Login()
Console.WriteLine("Check URL");

// Type UserName

// Type Password

// Clicked on Login Button

public void UnloadDriver()

Above marked area. Just described how you will get id from login page

  • Build your application or press (Ctrl + Shift + B)
  • You have to run Nunit window to run this code.
  • Now, open a project from file menu and choose the project dll file or you can drag and drop the dll.
  • Click on ‘Run’ button to define result pass / fail
