Comparing the Java code and the Go runtime, the visit method should call tree.accept(visitor)

    public T visit(ParseTree tree) {
        return tree.accept(this);
    }

The generated go code also have Accept methods in *_parser.go
still didn't found where are testes for go except for this https://github.com/antlr/antlr4/blob/master/.travis/run-tests-go.sh

another way is to get ride of ANTLR and write a raw parser in Go, but this lost the portability to other language. example: https://blog.gopheracademy.com/advent-2014/parsers-lexers/

there are on going work for visitor pattern's in go https://github.com/antlr/antlr4/pull/1841 , though it looks it would still take some time before it got merged
