Sr. No.
Point
QTP
Selenium
Remarks
1
Actual end user simulation, Is the test conducted using this tool equivalent to an end user action?
YES
NO
Selenium performs actions in the background on the browser. It modifies the DOM structure of the HTML page in order to perform actions on the page. To be more precise it executes javascript on UI objects within the webpage to perform actions like click, type, select etc. This is the reason why you can execute tests with the browser minimized. QTP claims to perform end user simulation, in other words executing QTP scripts is equivalent to a person performing those steps manually on the application.
2
Support for most UI Components
YES
YES
Certain events, methods and Object properties are not supported by selenium. But broadly most UI components are supported. QTP requires extra addins (plugins, not free) to work with dotNet components.
3
UI-Object management & storage
YES
NO
QTP comes built-in with object repository. Object repository management is quite easy in QTP. Selenium has no such built in feature but objects can be managed using UI-Element user extension. Other custom solutions like properties files can also be used in selenium. But for all such solutions the map file in selenium has to be hand-coded i.e unlike QTP the objects won't be recorded/added automatically .
4
Support for Dialog Boxes
YES
NO
QTP supports all kinds of IE dialog boxes. There is partial support for dialog boxes in Selenium. Some actions like retrieving the tittle of he dialog box can't be performed in selenium
5
Support for file upload scenario
YES
NO
This is the scenario where you upload a file located in your local
www.ITeLearn.com Call: +1-314-827-5272 Email: learn@itelearn.com machine onto the application using 'browse file' dialog or something similar. Selenium does not support this scenario due to JavaScript restriction. QTP has no problem whatsoever simulating this scenario.
6
Support for web browsers
YES
YES
QTP supports IE & Firefox. Selenium supports IE, Firefox, Safari and Opera and a few more browsers. But either tools are far far away from full cross-browser support. Don't expect scripts created using browser to run flawlessly in another browser.
7
Object Recognition Parameters, Recognition on the basis of WYSWYG (what you see is what you get)
YES
NO
Selenium recognizes objects on the basis of the DOM structure of the HTML Page. The UI objects in selenium have vague descriptions and don't comply with WYSWYG policy. QTP recognises and names objects based on properties which are more visible and obvious and are hence the objects have user friendly names.
8
Object Oriented Language support & Scalability (as in Integration with External tools utilities and libraries).
NO
YES
Selenium Supports JAVA, dot net and many other industry standard programming languages. QTP supports vb script only.
9
Integration with test management tool
With HP Quality Center and TestDirector
No
QTP integrates seamlessly with QC and TD. Test management and mapping the manual testing process with automation becomes a lot easier with this integration. I have not yet heard of any test management tool that can integrate seamlessly with Selenium. keep an eye out for Bromide though.

QTP wins this one hands down. This is one of the main reason why

Powerbuilder, TCL/TK), Terminal Emulation, Command prompt
selenium can't even be considered in many cases. Imagine real-time applications like trading terminals, risk management applications built in TCL/TK and powerbuilder. QTP supports most of these interfaces. Selenium on the other hand can work only on applications that open up inside a browser. But aren't most applications moving to the browser based platform? :)
