That timeout means that GWT has launched a browser pointed at itself, to run the test, but the browser didn't actually connect to us within 60 seconds. The constant isn't directly configurable, no, but it's not about the size of your test, just getting that first useful access from the browser (so it's supposed to encompass browser start time + network latency; 60s should be way over adequate!).
I have seen the timeout message happen due to a compile error in the GWT code, but you'd see those errors in the log also. I don't know much about the maven codehaus plugin, but here's roughly what GWT tests do: 1. GWT sets itself up as a web server on some random port. JUnitShell derives off the older GWTShell, so this should mean using our internal tomcat as the server. (I'm not sure your "tomcat with the cargo plugin" is relevant!) 2. That server is set to serve a synthetic GWT module, which is created via a generator that can reflect on your test code. 3. Depending on the -runStyle flag, GWT chooses a browser to launch. By default, we'd use HtmlUnit (mostly because we know where it is!), but there are other options available, including Manual (which has no timeout, and expects you to point a browser at GWT's server) and External (you give GWT an executable that accepts a URL as an argument). 4. If the browser we launch doesn't successfully access the web server we have, on that random port, you will get the timeout you cite. If it does access in time, the page should pull your code and start walking through the tests, reporting status and moving to the next test (or batch, depending on your batch strategy). I hope that helps. HtmlUnit does have some known issues, so especially if you see this happening "sometimes" you might want to experiment with either -runStyle Manual or -runStyle External to see if those are better-behaved for you.
