What do you know about Recovery scenario? What are the components of Recovery scenario? How do you use recovery scenario? When and where to use Recovery scenario?

As its name indicates, Recovery scenario gives us an option to recover from unexpected errors in QTP. It will recover from any type of errors whether it is a fatal error like object not found, path not found, system error etc… or a small error like pop up error, out of paper from printer etc…

The main components or steps that exist in a recovery scenario are:
Trigger:
A trigger is an even that initiates the recovery scenario to start working. These events can be fired by any action like ‘A sudden pop up’, ‘application error’, or change in the property of any object etc…

Action:
Action is a single or series of steps to be followed after the recovery scenario is triggered by an event. What to be done after recovery scenario is triggered? Any key board event, mouse event, calling any function to execute etc…

After these actions are executed, we can also set what to be done after this? Got o next executable step and go ahead from there? Etc…

In normal cases, recovery scenario is used when you are not able to find out the root of the error or place of the error. Because some errors may raise outside the QTP like ‘out of paper’ etc..
But if you know the line exactly where an error may raise in QTP, then you can use ‘Error resume next’ function instead of recovery scenario.
