QTP overview
What is QTP?
Quick test professional is a graphical user interface record-playback functional test automation tool. It supports functional testing of all enterprise applications developed using .NET,Java/J2EE,SAP, Siebel,Oracle, Peoplesoft,Visual basic etc.
It supports both windows and web applications.
QTP testing process consist of 6 main phases
- Create your test plan The test plan should include a detailed description of the test that consist exact steps to follow, data to be input, verification and validation of objects in the application.
- Recording a Session on your application When you are navigating through your application QTP displays each step you perform in the form of a collapsible form of icon-based tree. A step is an action that you perform in your application. It can be a clicking a link or image or entering data in a form.
- Enhancing your test you can enhance the test by putting checkpoints into your test which allow you to search for a specific value of a page,object or string which helps you to understand whether or not your application is functioning properly. You can add the check points during the recording of a test. you can also add conditional and logic statement to your test.
- Debugging your test You can debug the test to identify the operation of a test.
- Running your test Run the test to check the behavior of the application. While running QTP connects to your application and performs each step in your test.
- Analyze the Results Analyze the results to identify the defects in your application.
- Reporting Defects You can create defect reports in defecting reporting tool.
Features: QTP 8.0
- Operates stand-alone
- Identifies objects with unique object recognition.
- Enables thorough validation of applications through check points
- Reliable script execution from Build-to-Build.
In next post i will explain how to execute the test case using QTP.

1 commentFactory method Designpattern using C#
The factory method pattern is a creational design pattern used in software development to encapsulate the process of creating the objects.
Concerns:
- Which object needs to be created.
- Managing the life time of the object.
- Managing the build-up and tear down concerns of the object.
Definition:
“Define an interface for creating an object, but let subclasses decide which class to instantiate”
C# Implementation of Factory method
abstract class Factory
{
public abstract Product GetProduct(); //Factory Method Declaration
}
——————————————————————————————-
class concreteFactoryforProcuct1 : Factory
{
public override Product GetProduct() //Factory Method Implementation
{
return new Product1();
}
}
——————————————————————————————–
class concreteFactoryforProcuct2 : Factory
{
public override Product GetProduct() //Factory Method Implementation
{
return new Product2();
}
}
——————————————————————————————–
interface Product
{
void GetDetails();
}
class Product1 : Product
{
public void GetDetails()
{
Console.WriteLine("Product1 Details are Called");
}
}
class Product2 : Product
{
public void GetDetails()
{
Console.WriteLine("Product2 Details are called");
}
}
——————————————————————————————–
protected void Page_Load(object sender, EventArgs e)
{
Factory[] objFactories = new Factory[2];
objFactories[0] = new concreteFactoryforProcuct1();
objFactories[1] = new concreteFactoryforProcuct2();
foreach (Factory objFactory in objFactories)

If you want to run your existing ASP.NET 1.1 websites under .NET Framework v1.1 please read this post Configuring .NET Framework 1.1 on windows vista and follow the below steps.
1. Open IIS 7 by going through Control Panel/Administrative Tools and please select the ISAPI and CGI Restrictions option from IIS section.
2. Allow the ASP.NET 1.1 in the ISAPI/CGI restrictions.
3. Make sure that your application pool should run in a 32-bit mode + v1.1 + classic mode.
Below are the commands using appcmd.exe tool which would do this.
appcmd.exe can be found under C:\Windows\System32\inetsrv.
- appcmd apppool set /apppool.name:”ASP.NET 1.1” /enable32BitAppOnWin64:true
- appcmd apppool set /apppool.name:"ASP.NET 1.1" /managedRuntimeVersion="v1.1"
- appcmd apppool set /apppool.name:"ASP.NET 1.1" /managedPipelineMode:"Classic"
- appcmd apppool set /apppool.name:"ASP.NET 1.1" /autoStart:true (optional)
4. Alternatively you can also use this option to run your application pool under .NET FW v1.1

1 commentConfiguring .NET Framework 1.1 on windows vista
Configuring .NET FW v1.1 on Windows vista is bit tricky.
Here are the steps you need to follow
- Download .NET Fx from .NET FW v1.1 because by default vista come up with .NET FW v2.0 and v3.0.
If you install FW v1.1 alone at the end of installation you will get the following error
RegSvcs.exe – Common Language Runtime Debugging Services
——————————-
Application has generated an exception that could not be handled.
Process id=0×9a0 (2464), Thread id=0xf70 (3952).
Click OK to terminate the application.
Click CANCEL to debug the application.
—————————
OK Cancel
—————————
The above error is in .NET FW v1.1 which is known to occur on window vista.
This issue is resolved in Microsoft .NET FW 1.1 SP1, however you will need to use the following procedure
- Download .NET FW v1.1 SP1 .
- Save both installations to the same directory.
- Ensure that FW 1.1 Redistributable package name is dotnetfx.exe.If not change its name to dotnetfx.exe
- Ensure that FW 1.1 SP1 is named dotnetfxsp1.exe. If not change its name to dotnetfxsp1.exe
- Run the following 3 commands using the order shown
dotnetfx.exe /c:”msiexec.exe /a netfx.msi TARGETDIR=C:\<DirectoryName>”
dotnetfxsp1.exe /Xp:C:\<DirectoryName>\netfxsp.msp
msiexec.exe /a c:\<DirectoryName>\netfx.msi /p c:\<DirectoryName>\netfxsp.msp
- Install both Microsoft .Net Framework 1.1 and Service Pack 1 by running C:\<DirectoryName>\netfx.msi
