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.
