What is the use of function generator?
The Function Generator provides a quick, error-free way to program scripts. We can :
> Add Context Sensitive functions that perform operations on a GUI object or get information from the application being tested.
> Add Standard and Analog functions that perform non-Context Sensitive tasks such as synchronizing test execution or sending user-defined messages to a report.
> Add Customization functions that enable we to modify WinRunner to suit our testing environment.
