You have to create a a subclass of GwtTestCase which requires you to specify a GWT module.
Here an example for java.util.Random emulation within GWT SDK: https://github.com/gwtproject/gwt/blob/master/user/test/com/google/gwt/emultest/java/util/RandomTest.java Once you run the GwtTestCase using JUnit it will compile the GWT module and execute the test using HTMLUnit. I think by default HTMLUnit will run in FireFox mode. You can find a testing guide at http://www.gwtproject.org/doc/latest/DevGuideTesting.html . It is probably not super up-to-date but it gives you the general idea and shows you how to set parameters to run tests in either HTMLUnit or manually in a real browser. -- J. -- You received this message because you are subscribed to the Google Groups "GWT Users" group.
