QTP Tricky Questions Answers fallows!

Answer 1: In QTP point of view we automation applications where there is proper addin. There are few cases where we can use win32 API and shell programming to achieve.

Example: use win32 query to get the handle or processed of the app and use some API to act on it...this will be a work around not a solution.

Answer 2: use DHTML properties ....use object.attributes...u will get all DHTML properties of that particular element in a collection.

Answer 3: There are many out of which is time consuming it eats lot of time and sometimes, it yields wrong results also in case of dynamic environment.

Answer 4: I think Space and time may be the constraints, because I never used it. It is pretty waste of time to use it.

Answer 5:  To execute JavaScript we have to fallow these steps

1. Open HKEY_LOCAL_MACHINE\SOFTWARE\Mercury Interactive\QuickTest Professional\Configuration_UI\ScriptMgr
2. Create a new String value with name AltProgID and value "Mercury.JSScriptMgr" and change the value of "Create" to 1
3. Create a new child key inside the key                             HKEY_LOCAL_MACHINE\SOFTWARE\Mercury Interactive\QuickTest Professional\Configuration_UI\ScriptConstants                                                               {0ECD5785-BE7D-11d4-8EAF-11135659EC56}
4. Repeat the same steps for the below key                           HKEY_LOCAL_MACHINE\SOFTWARE\Mercury Interactive\QuickTest Professional\Configuration
5. Open                                                                                                                                C:\Program Files\Mercury Interactive\QuickTest Professional\bin\QTEditor.ini
6. Add the below parameter to [General options]                                                             AllowJavaScript = 1                                                                                                 DisableVBScript = 1
7. Done 

Answer 7: U can record but not as a web application but a standard windows application

Example: Window("Mozilla Firefox").WinObject("MozillaWindowClass").Type "sivakumar"

Answer 8: Repository parameters enable you to specify that certain property values should be parameterized, but leave the actual parameterization to be defined in each test that is associated with the object repository that contains the parameterized test object property values.

Repository parameters are useful when you want to create and run tests on an object that changes dynamically.

Repositories collection is a collection object that enables you to programmatically manage the run-time collection of shared object repository files associated with the current action, for more details check QTP Help file.

Answer 9: checkout for .VOT files in dat folder of the installation

Answer 10: NO

How to connect to Quality Center form Quick Test Professional

Quality Center:We can use Quality Center to create a project (central repository) of manual and automated tests and components, build test cycles, run tests and components, and report and track defects. You can also create reports and graphs to help you review the progress of test planning, runs, and defect tracking before a software release. When you work in QuickTest, you can create and save tests and components directly to your Quality Center project. You can run QuickTest tests or components from Quality Center and then use Quality Center to review and manage the results. You can also use Quality Center with Business Process Testing support to create business process tests, comprised of the components you create in either QuickTest or Quality Center with Business Process Testing support.

Advantages of Quality Center:

Quality Center is a single application for complete Test ManagementStarts with Requirements, goes through Test Planning and Test Execution, and on through Defects.Each of these items can be linked or associated with each other.

All about QTP Descriptive Programming

What is Descriptive Programming?

In QTP if we want to do some actions/operation on an object that is not there in the object repository then we can use or go for Descriptive programming.

With out using QTP OR we can store properties of Test objects in the QTP Script by defining the Object properties.

Advantages of Descriptive Programming:

1. We will be able to work on writing QTP scripts even before the application is NOT available. It will help to increase the utilization of the Automation scripts as it will be immediately available once the application get released.

2.We can define the properties of an object without considering the parent objects in the hierarchy. i-e Object identification will not depend on its parent object.

there are 2 ways to describe your Test Objects.

One is description in form of the string arguments.

For Ex:  text box having html code as < input type=”text” name=”txtUserSiva” > can be accessed as below.

Browser(“Browser”).Page(“Page”).WebEdit(“Name:=txtUserSiva”,”html tag:=INPUT”).set “AutomationTestingwithQTP”.

The 2nd way is using Decription.create as below.

Set objDesc = Description.Create

objDesc(“html tag”).value= “INPUT”

objDesc(“name”).value= “txtUser”

Browser(“Browser”).Page(“Page”).WebEdit(objDesc).set “AutomationTestingwithQTP”.

Disadvantage of Descriptive Programing:

First disadvantage of Descriptive programming is Maintenance will be difficult.
Since Object repository will be stored in centralized place, property definition for any Object can be easily changed at any time if the application developer changes the property of the actual object/control.

But, in descriptive programming (DP) it is difficult to change the object property as each QTP developer will be defining object property in many places using DP.

For example, assume that you and team member are developing automation test scripts for testing gmail application.
Gmail login script will be used in many test scenarios.

Assume that you are automating some scenarios and your team member is automating some other scenarios.
In case of Object Repository, you and your team member will be forced to use same object description for login page controls/Objects (e.g username, password, login button).

So in future if Google changes any property (e.g change the button name from “login” to “get into gmail”), all the scenarios can be easily updated just by updating this change in Object repository.

But in case of DP, there is a possibility of defining the login button in multiple places. One definition by you and another by your team. (Anyway proper Team Coordination will avoid this issue, but practically it is very difficult to achieve this coordination.).

So, comparatively updating DP style coding is bit difficult if the application properties got changed.
