Just played with the -runStyle Manual option.... I am afraid that is not a correct option for me as I will run the tests during the nightly build and with -runStyle option Manual will stop when running the test and I have to manually copy/past the displayed url, like explained in: http://code.google.com/webtoolkit/doc/latest/DevGuideTesting.html#Manual_Mode. Of course this isn't possible during a nightly build.
I will try the option "-prod", this might bypass the HtmlUnit code that might give problems as you explain above. I tried this option in Eclipse and the test do run fine with this option. I hope this will solve the problem, as I have no idea what else it could be :( In Eclipse, the GWT tests always run fine (through launch files, I don't use the plugin), and never give me the timeout problem. If you have any more ideas, giving my posts above, please let me know? -- http://groups.google.com/group/Google-Web-Toolkit-Contributors
