How does UFT perform the Click method when using the Web Add In?

Question

I am testing a highly javascript based application on Internet Explorer 8.0 with UFT 11.50. I would like to know how UFT implements the "Click" method under the hood when using the Web Add In. Does UFT send a windows mouse event? Does it fire an event (onclick, onmousedown, onmouseup)? I have been seeing some mixed results with my application.

Answer 1

It can do either, by default UFT replays using DOM events but you can change the replay type to device in which case it queries the HTML element's location and simulates a mouse click on that location.

The replay mode is controlled by Tools->Opitions->Web->Advanced->RunSettings or in the script by:

Setting.WebPackage("ReplayType") = 2 ''# Changes to device mode
Setting.WebPackage("ReplayType") = 1 ''# Changes to event mode

Note that in event mode UFT doesn't just send a click, it sends other events that typically are used by applications (such as focus, mousedown and mouseup) unless the registry value ReplayOnlyClick in the WebPackage settings is set to 1.
