UFT / QTP中的错误处理

Question

I've a framework where the methods are called inside an action from Function Libraries. I'm trying to do error handling to avoid errors thrown by code written inside the function Libraries.

Below is my action code:

on error resume next
call TestMe()
if err.number Then: msgbox err.description
on error goto 0

And here is the function inside function library:

Function TestMe()
   x = 1/0
End Function

When I execute my test, on error resume next doesn't seems to be working as I get an error pop-up for division by zero inside the function TestMe().

How can I get these error handled without moving the code?

Answer 1

Surprisingly with all the time using QTP/UFT never came up against such case. Was quite intriguing as well. I Found out (or so it seems at first glance) that the scope of on error resume next is limited to its level (Library/Action) and couldn't be carried over to either.

You might wanna try something like:

Action Code:

Call Test3()

Function Library:

Function Test1()
      x = 1/0
End Function

Function Test2()
   Call Test1()
   MsgBox "Test2"
End Function

Function Test3()
   On Error Resume next
   Call Test2()
   MsgBox err.Description
End Function

The execution using this statement continues until it finds a handler. So you may set up a condition where ever you deem fit.

Another alternative is to use a flag (could be an environment variable) like

Environment("Flag") = True

Whose condition can be checked directly in action code

Hope this helps. I'll still try to dig up more about this
