Dynamic Synchronization in QTP

Dynamic synchronization allows waiting till the object property is changed or till time out.

Sample example:

Window("WinFlight").ActiveX("ThreedPanelControl").WaitProperty "text", "Insert Done...", 10000

The waitproperty can be inserted using Insert Synchronization point or we can manually add the waitproperty method by typing  typing it.

Apart from this we can also add synchronization point using following code also

Sample code: 1

Function ManualSyncPoint (Object,propertyname,propertyval,timeout)

Do

If Object.GetRoProperty(propertyname)=propertyval Then

            'if propertyname and propertyval match, come out of the loop and execute next step

           

                        Exit Do

           

            Else

                        Wait(1)

            End If

Loop while(i<=timeout)

End Function

In the preceding method we have used the static wait; we can implement it without using wait statement as well.

Sample code:2

Function ManualSyncPoint2(Object ,propertyname, propertyval, timeout )

sttimer = Timer

'Timer allows to get the number of seconds elapsed since midnight

(12:00 AM)

Do

If Object.GetROProperty(propertyname) = propertyval then

Exit Do

else

end if

endtimer = Timer

'The difference between the two timer objects provides the number of seconds we need to determine for timeout

Loop While ( int (endtimer-sttimer) <= -timeout)

End Function

Function that allows to wait till object exists

Sample code:3

Function WaitTillExists(Object, timeout )

loadtimer = Timer

Do

isObjectExists = Object.Exist

If isObjectExists = true Then

Exit Do

else

End If

completetimer = Timer

Loop While(completetimer-loadtimer <= timeout)

End Function
