[Webtest] dataDriven: fails all subsequent tests with Unknown Host Exception

[George Policello]

I am using the dataDriven construct to reach sites through a specialized
proxy, named Proxy in program extracts below.

 

When I give the dataDriven a spreadsheet with a list of URLs with valid
Titles for the target pages good things happen, it works! However, if I
force a bad Title (URL 2 below, eBay), the test fails (as expected) with
a "Wrong Title" message, as it should. BUT after that forced failure,
URLs 3 and 4 fail as in next paragraph but work if line 2 is returned to
a valid Title.

 

After the first failure, all subsequent tests fail, wrongly, with
"Unexpected exception caught: java.net.UnknownHostException."

 

The repeating pattern in the Stack Trace is

The Webtest xml file. Proprietary stuff removed but it works in other
test venues.
