GWT : Getting a 404 error when unit testing RequestBuilder - gwt

Question

I use the GWT RequestBuilder, and for testing purposes, I'd like to load a json file in the server.
It works perfectly with the DevMode, but throw a 404 error with GWTTestCase.
With RPC, there is a fix adding <servlet path=".." class="..."/>, but what can I do with static content ?
I could easily use #TextResource, but it's not the goal of my UnitTest (which is in fact a functionnal test)

Answer 1

Static resources can be bundled with a module by putting them in the module's public path.

Answer 2

I used (once again) Thomas's answer to resolve the problem. My module is io.robusta.fora.comments.Comment.gwt.xml and I've put my user.json file in the io.robsuta.fora.comments.resources package.
I had so to add in Comment.gwt.xml file : <public path="resources"/>
Then the GWTTestCase is straightforward :
public class GwtRestClientTest extends GWTTestCase{
#Override
public String getModuleName() {
return "io.robusta.fora.comments.Comments";
}
public void testGET(){
String base = GWT.getModuleBaseURL();
System.out.println(base); //-> http://192.168.0.10:53551/io.robusta.fora.comments.Comments.JUnit/
GwtRestClient client = new GwtRestClient(base); //base url
AsyncCallback<String> cb = new AsyncCallback<String>() {
#Override
public void onSuccess(String result) {
System.out.println(result);//->{id:1,email:"jo#robusta.io"}
finishTest();
}
#Override
public void onFailure(Throwable caught) {
caught.printStackTrace();
}
};
client.GET("user.json", null, cb);//fetch my json file with no params
delayTestFinish(3000);
}
}
