i prefer qtp.

I think this is sufficient for u to understand clearly.

What We Recommend

QuickTest Pro is our functional testing tool of choice!


Most customers are in either of two situations:
Existing WinRunner customers asking “Should we switch to QuickTest Pro?”
New customers asking “Which should we get, WinRunner or QuickTest Pro?”

We have been implementing Mercury’s products since 1992 and have senior level expertise in WinRunner. We have been implementing WinRunner since the very first version of it. So like many existing WinRunner customers we have a huge knowledge investment in WinRunner ourselves. However we have worked on the Mercury development team on the QuickTest Pro 6.0 and 6.5 releases, and have solid real-world experience in implementing QuickTest Pro since the 6.0 release. We have found it to be a great tool to use and recommend it to all customers! Overall, we recommend using QuickTest Pro unless for some reason you have to use WinRunner due to an unsupported environment not existing in QuickTest Pro.

Overall, QuickTest Pro is easier to use and implement for both technical and non-technical testers in comparison to WinRunner. QTP offers many features that are found in WinRunner, but are easier to use. QTP also offers many features not found in WinRunner that make test script creation, enhancement and maintenance easier.

Let’s quickly discuss some key issues:
The WinRunner interface forces the user to look directly at TSL code. TSL is the WinRunner programming language developed by Mercury. It is based on the “C” programming language and therefore looks very similar. For testers who do not have a technical background, they are not always comfortable with having to always look at code. However QuickTest Pro offers a “Tree View” which is an icon-based view of the script. This is very easy to get used to and non-technical people adapt to it quicker and feel more comfortable working with it. For the technical user, they can always switch over to the “Expert View” in QuickTest and look directly at code, and program away using VBScript.
WinRunner uses TSL which is a proprietary language of Mercury. These types of languages can be very restrictive and you are limited on available resources. QuickTest Pro use the Microsoft programming language VBScript which is very powerful, has lots of capabilities and there are lots of resources available.
We feel that there are many more “point and click” features in QuickTest Pro than WinRunner. This makes its use easier.
All the same features found in WinRunner are found in QuickTest Pro plus more.
Data Table integration is much easier and simpler with QuickTest Pro.
Data Driven Testing is easier with more options in QuickTest Pro.
Script enhancements are typically easier with QuickTest Pro because it has the Active Screen where the windows and objects in your application are captured for later use. Using a “point and click” capability you can easily interface with objects, their definitions and create checkpoints after having recorded a script – without having to navigate back to that location in your application like you have to with WinRunner. This greatly speeds up script development.
QuickTest Pro currently has built in integration with WinRunner in order to be able to call existing scripts, which is great for customers who already have a large test script investment with WinRunner. Likewise WinRunner 8.0 is to have the ability to also call QuickTest Pro scripts. This eases the transition from WinRunner to QuickTest Pro for existing customers.
Parameterization is much easier in QuickTest Pro and basically anything in QuickTest Pro can be parameterized (statements, checkpoints and the Object Repository).
Capturing various output values is easier and simpler with QuickTest Pro. Using this capability with parameterization enables you to easily develop scripts that can do more in regards to testing.
We have been implementing QuickTest Pro in real-world environments and have found it much easier to use, advance features are easier to implement and the script development is quicker. We really enjoy using QuickTest Pro and highly recommend it as the functional testing tool to use.

WinRunner
Summary:

This product is a mature tool that has been around since approximately 1995. It interfaces with most of the leading development toolkits using the WindowsAPI and toolkit DLLs to interface with the “Application Under Test”.

WinRunner offers a recording feature that will watch the individual tester and generate a test script to simulate the same actions just performed. The script is displayed as a program which can be enhanced with checkpoints, logic and special coding/programming.

WinRunner also has integration with Excel spreadsheets for data driven testing and the ability to write data out in Excel format or in simple text files.

Here is the description from the Mercury “Features and Benefits” section of the WinRunner web page:
Significantly increase power and flexibility of tests without any programming: The Function Generator presents a quick and error-free way to design tests and enhance scripts without any programming knowledge. Testers can simply point at a GUI object, and WinRunner will examine it, determine its class and suggest an appropriate function to be used.
Use multiple verification types to ensure sound functionality: WinRunner provides checkpoints for text, GUI, bitmaps, URL links and the database, allowing testers to compare expected and actual outcomes and identify potential problems with numerous GUI objects and their functionality.
Verify data integrity in your back-end database: Built-in Database Verification confirms values stored in the database and ensures transaction accuracy and the data integrity of records that have been updated, deleted and added.
View, store and verify at a glance every attribute of tested objects: WinRunner's GUI Spy automatically identifies, records and displays the properties of standard GUI objects, ActiveX controls, as well as Java objects and methods. This ensures that every object in the user interface is recognized by the script and can be tested.
Maintain tests and build reusable scripts: The GUI map provides a centralized object repository, allowing testers to verify and modify any tested object. These changes are then automatically propagated to all appropriate scripts, eliminating the need to build new scripts each time the application is modified.
Test multiple environments with a single application: WinRunner supports more than 30 environments, including Web, Java, Visual Basic, etc. In addition, it provides targeted solutions for such leading ERP/CRM applications as SAP, Siebel, PeopleSoft and a number of others.
Simplify creation of test scripts: WinRunner's DataDriver Wizard greatly simplifies the process of preparing test data and scripts. This allows for optimal use of QA resources and results in more thorough testing.
Automatically identify discrepancies in data: WinRunner examines and compares expected and actual results using multiple verifications for text, GUI, bitmaps, URLs, and databases. This ensures stable functionality and execution of business transactions when the application is released into production.
Validate applications across browsers: WinRunner enables the same test to be used to validate applications in Internet Explorer, Netscape, and AOL. This saves testing time and reduces the number of scripts that must be developed and maintained.
Automatically recover tested applications from a crash: Unexpected events, errors, and application crashes during a test run can disrupt the testing process and distort results. WinRunner's Recovery Manager enables unattended recovery and provides a wizard that guides the process of defining a recovery scenario.
Leverage investments in other testing products: WinRunner fully integrates with our other testing solutions, including LoadRunner for load testing and TestDirector for global test management. Moreover, organizations can reuse WinRunner test scripts with QuickTest Professional.
