Test Automation Framework:

Basically the framework have been created to make the 
automation process easier. Ex: In the application 
development you might have some structures to place the 
files and the development team will follow that..

QTP does not use the framework itself. We decide the 
framework which we are gonna use and make use of QTP for 
that framework.
Some of frameworks are:
Data Driven 
Key word Driven
Hybrid(Combination of above 2 )
Mostly Hybrid frame work is used...

To Start the Test Process:
Decide the framework which would choose the AUT
Let have a example of Data Driven framework.
Here in this frame work you will have a Driver file and you 
can also find the data for different actions.
Consider there are 9 test cases and we use 9 action for 
each test case and we also have a status flag for each 
action.
we need to run the test once after changing the status.

Framework is a procedure in which we can write & execute the
automation script.in other words Framework is a guide,rule
or procedure to run the automated script with less manual
intervention or without manual intervention.
types of framework:
1.Modularity framework
2.test driver framework
3.Data driven framework
4.keyword driven framework
5.hybrid framework
