Hi everybody, I have put together some of the advantages and disadvantages of Quick Test Professional tool below. As usual, if you feel anything needs to be added kindly leave a comment. Thanks.

Please read the complete list of QTP advantages here.

2. Support for record and playback and ability to edit scripts after recording. Also different recording modes are provided in QTP viz. Normal, Analog & Low level.
3. Excellent Object Identification process / mechanism
4. Support for different addins like Java, Oracle, SAP, .NET, Web Forms, Siebel, PeopleSoft, Web services, Main frame (Terminal Emulator) etc.
5. Ability to let you enhance the existing tests even without the AUT (Application under test) through active screen.
6. Supports all popular Automation frameworks - Keyword driven testing approach, Data driven testing approach, Modular testing approach, Hybrid frameworks etc.
7. QTP comes with an inbuilt IDE, which is simple and easy to use.
8. QTP uses VBScript which is English-like and very easy to learn and gain expertise. We have plenty of resource available to learn VBScripts.

10. QTP can be integrated with Test management tools like QC (Quality Center), Test director and also functional test tools like Winrunner.
