There are very few cases when onError would be called, the most common
one being a timeout if you call setTimeoutMillis with a non-0 value.

The easy way to reliably have it is to Thread.sleep() on the server
side with a long value while having a short timeout on the client
side. Maybe GWT's own unit tests could inspire you?

(note that it won't run reliably in -runStyle:HtmlUnit due to a but in
HtmlUnit)

Thomas, I managed to do it already, with the same way, given a sleep in the servlet.
Now another issue , I am trying to crack is I have to use this mode for running test in production mode

-runStyle Manual:1
when I run it , get the url , past in browser getting disconnected , 

The problem is there is a servlet generate a picture and return 
ind devmode url is this - http://127.0.0.1:8888/test/NVM_hover_bg.png

but in test mode it is searching a servlet By this url
http://192.168.1.3:1627/com.test.client.test.JUnit/pic.png

and getting disconnected since its not able to get this servlet.
Could u please help me in this issue, 
Thanks
JP

In GWTTestCase, servlets have to be declared in a .gwt.xml using the
<servlet/> element, and called using a path relative to
GWT.getModuleBaseURL() (or GWT.getHostPageBaseURL() if you want,
they'll be the same during tests)
You can either declare the <servlet/> in your module's gwt.xml or
create a new gwt.xml just for the tests, that <inherits/> your app
module and declare the <servlet/> (make sure your
GWTTestCase.getModuleName() returns the test-specific module).
Again, have a look at how it's done in GWT's own tests (see links in
my previous message, and sibling files and packages)
