Trouble running the GWT JUnit test cases via Eclipse

[Shrivallabh]

Hi all,

I referred to the following article to run unit test cases.

http://thediscoblog.com/2007/04/28/3-steps-to-running-gwt-junit-tests-in-eclipse/

I am getting the following error.

The build path seems ok as per the tutorials/

[charlie...@gmail.com]

Are you sure you have the source in the classpath, as step 3 in that
tutorial explains? I use Eclipse to runs tests and that is really the
only tricky part (you also have to have any additional libs you are
using in the classpath, but that is normal).

Also does your test run outside of Eclipse?

Try maybe a simple test first, create one with JUnitCreator, compile
it, run it, make sure you understand all the parts there, and then try
to run that same simple test in your IDE. By looking at the scripts
ApplicationCreator and JUnitCreator output you can see all the
necessary paths and elements.

[mP]

I personally find its a good idea to include client/server sub
packages under your test package.

+ /test
Test.gwt.ml
/client/TestGwtTestCase.java

etc

[ethael]

I have the same problem... can anyone tell what is wrong? probably
gwt.xml file.... hm?

Hi

Just wanted to confirm that adding the src to the classpth in the
junit run configuration solved the problem.
