Question

Can anyone suggest whether I should use Surface Automation technique for creating automation or not?

Answer 1

Hello, in my opinion you should avoid using Surface Automation for creating automation as it has following disadvantages:

• It uses screen coordinates to click on objects. So accuracy will be very low.
• If the target application is not active, there is a possibility of global send keys passing the values to the wrong application.

Though Surface Automation has a lot of advantages too because of which it is used:

• When you can’t use controls programmatically (i.e. by element identifiers)
• When the system under automation is changing (i.e. element identifiers are changing). 
• Also, it is faster than ’normal’ scripting.

So, it completely depends on your requirement and feasibility.
