Synchronization in UFT

When we automate the script most of the time we faced several issues with performance of application. sometimes application becomes slow in response sometimes fast. then how we show make sure that our script should run in irrespective of the application performance and response?

all automation tools provide specific functions which handles these performance issue. UFT also has Synchronization mechanism to make sure that script will not fail.

Lets discuss more about the Synchronization.

There are 5 different ways to handle the synchronization.

1. WaitProperty
2. Exist
3. Wait
4. Sync(only for web based apps)
5. Default Synchronization

WaitProperty:

WaitProperty is a method  which can be apply on any object in UFT. It takes the property name, Value and Timeout value as input to perform the sync. It is a dynamic wait, it means once the object is get visible/enable or state becomes true corresponding action gets performed. so it is highly recommended options.

Example : lets put wait for 10secs

Dim obj

Set obj = Browser("XX").Page("XX")

obj.Link("select").Click

obj.Link("XX").WaitProperty "text", "Simple Interest",10000

obj.Link("XX").Click

Exist: Exist menthod ensure that object is present on the screen or not. Exist is a method that takes the Timeout value as input to perform the sync.  it is a dynamic wait similar to Waitproperty and hence this option is also recommended.

Dim obj

Set obj = Browser("XX").Page("XX")

obj.Link("XX").Click

If obj.Link("XX").Exist(30) Then

obj.Link("XX").Click

Else

Print "object does not exists";

End If

Wait

Wait  Method puts hardstop on wait. if you use this method then thread of execution will stop for defined set value.this wait method is not recommended unless you don’t have another option.

Dim obj

Set obj = Browser("XX").Page("XX")

obj.Link("XX").Click

wait 30

obj.Link("XX").Click

Sync Method

sometimes pageload time varies. to wait for it Sync method can be used. Method can be used only for web applications where there is always a lag between page loads.

Dim obj

Set obj = Browser("XX").Page("XX")

obj.Link("XX").Click

wait 30

obj.Link("XX").Sync

Default Synchronization: When user hasn’t used any of the above sync methods, still QTP has in build Object synchronization timeout which can be adjusted by the user.
