[Webtest] Unselect preselected value in setSelectField

[Mart Toom]

Hi,

I have in the application a multi Select field that has preselected value and I need to verify script on page that doesn't allow to save this form when no values is selected.
Unselecting preselected value can be easily done with browser by using ctrl button.

Is it somehow possible also with WebTest?

----------------------
<input name="_permissions" value="marker" type="hidden">
<select name="permissions" id="permissions" style="height: 250px;" multiple="multiple">

<option value="1" selected="selected">accept_reject</option>

<option value="0">add</option>
<option value="2">complete</option>
<option value="4">invoice</option>
<option value="3">view</option>
</select>

BR,

Mart T
