Explain the QTP Tool interface?

The tool interface of the quick test professional is the focus of this article. The tool interface of the quick test professional consists of certain elements:

1. Title bar: This bar displays or holds the name of the test that is currently open.
2. Menu bar: This bar holds all the quick test commands that one may need often.
3. File tool bar: This bar holds all the quick test commands or tools that one may need in the management of the tests.
4. Test tool bar: This bar holds all the quick test commands or tools that may are required in the creation as well as management of the tests.
5. Debug tool bar: This bar holds all the quick test commands that may be required while debugging of the tests. Usually this bar is not displayed along with the other bars when the quick test professional is launched. If the quick test professional is not displaying the debug bar by default then you need to go to the view and select debug tool bar from the tool bars sub list.
6. Status bar: This bar displays the current status of the test that is currently under execution.
7. Action tool bar: This bar holds a list of actions using which one can view the individual details of the whole test flow or an individual test or action. Just like the debug tool bar this tool bar is also not displayed by the quick test professional by default. For displaying it along with the other bars you need to go to the view menu and select action tool bar from the sub list of the tool bars. But if you have inserted an external action or a reusable action in to your test scripts, then the quick test professional displays the action tool bar automatically.
8. Test pane: This pane consists of two tabs which enable the viewing of the test in two view modes namely: the expert view and the key word view or the tree view.
9. Test details pane: This pane holds the active screen of the quick test professional.
10. Data table: This table consists of two tabs namely: the action tab and the global tab. Both of these tabs together provide you assistance during the parameterization of your tests.
11. Debug viewer pane: This pane consists of three tabs namely, the expressions, the commands and the variables. All of these 3 tabs provide you assistance while you debug your tests. However, there is one issue with debug viewer pane which is that you can open it only when you pause the test run at a break point.

As we know that the quick test professional provides two standard views as well way to modify the test scripts namely:

1. Key word view and
2. The expert view

- It is because of these views that the quick test professional is said to possess an IDE or integrated development environment. 

- The quick test professional comes with several standard IDE features like break points etc.

- The scripting language that is used by the quick test professional i.e., the VBScript provides support for the classes but not for the other aspects of object oriented programming like inheritance, polymorphism etc. 

- It lacks some other features such as:

1. Cannot use some visual basic key words.
2. Does not have an integrated debugger.
3. No event handler
4. No forms editor

- The debugger has got a limited functionality when compared with the debuggers of java, VBA, VB.NET and so on.
