Hi Leon,
thank you for your answer (and your work with gUnit), I have found a temporary workaround to be able to load the group and test the tree grammar for the moment.
The code loading the template group file is directly inserted in the tree grammar instead of inside the external class containing the main() method.
Looks like this:
@header {
package com.foo.bar;
import java.io.*;
import org.antlr.stringtemplate.StringTemplateGroup;
}
...
myStartRuleInMyTreeGrammar
@init {
try {
FileReader groupFileR = new FileReader("treeKoRuGenClasses.stg");
StringTemplateGroup templates = new StringTemplateGroup(groupFileR);
groupFileR.close();
this.setTemplateLib(templates);
} catch (FileNotFoundException fnfe) {
fnfe.printStackTrace();
} catch (IOException ioe) {
ioe.printStackTrace();
}
Stanislas Herman.

Objet : Re: [antlr-interest] gunit tree testsuite can't find the group template file
Hi Stanislas,
gUnit currently can only test on plain parser/tree grammar, and
doesn't support loading group file(*.stg) or setting customized tree
adaptor yet.
The functionality such as walker.etTemplateLib() and
parser.setTreeAdaptor() will be added into the next release. Sorry
for the inconvenience.
Leon
