A test automation framework is a set of assumptions, 
concepts, and pratices that provided support for automated 
software testing.

In our company we follows hybrid model framework.

Framework....it is the model or structure we follow for a 
project. It is the approach that we follow to automate the 
project. There are so many types of framework in QTP.

1. Datadriven frame work

2. Keyword driven frame work

3. Module driven framework

4. Hybrid driven frame work

The framework you choose, depends on the model of your 
project. Usually most of projects fall under hybrid driven 
frame work.

Datadriven framework: Here we divide the entire project in 
to modules and start automation by writing datadriven 
scripting for each one of them. We will have test data 
either in excel sheet or flat files or from database...we 
will pass that test data in to the script and perform data 
driven testing.

Keyword driven framework: 

Firstly we should add the objects to repository( Shared 
repository is preferable)

Then we can generate/write scripts for each functionality 
and save them as the library files ( .vbs files)

Then we have to associate all these library files(which are 
generated to test different funtionalities) to Quick Test.

For example consider Flight application

we can generate library files for 
login()
open order()
fax order()
delete order()
update order()
logout()   etc..,


select case k = datatable.value("keys",1)

case A : login()
case B : open order()
case C : fax order()
case D : delete order()
case E : update order()
case F : logout() 

end case

Module driven frame work: we will divide entire project in 
to modules and write functions or procedures for each and 
every module and automate the project.

Hybrid driven framework: it is combination of Datadriven 
and module driven framework.

Hope this clarifys your query...

Frame work : Frame work is a set of guidelines given by
experts to accomplish the task in a systematic manner.

There are 4 types of frame works:
1. Linear / Decomposition / Modular frame work
2. Keyword driven frame work.
3. Datadriven frame work.
4. Hybrid frame work.

hi kumar,

  Your explanation is good.
 In the same way i need some help from u technically.
