An alternative to
stat -> {$stat.st} ;  // for every stat[ement]
is
use rewrite in your grammar file
options {output=template;
	 rewrite=true;
	}
and use TokenReWriteStream instead of CommonTokenStream in the testrig
TokenRewriteStream tokens = new TokenRewriteStream(lexer);

See the /templates/rewriter/1pass example in the antlr book
