Hi,
I guess you talking about the capturing snapshot on object or desktop level. If i'm correct you can see that property in
Tools > Current Project Properties > Visualizer Then
Capture style - Specifies the area TestComplete will take a screenshot of. Possible values include –
| Top-level parent |
(Default) The top-level application window with which you are working. |
| Desktop |
The entire desktop. |
| Note: |
When you work with Android applications, Test Visualizer always captures the entire screen of the mobile device. |
