Subject: [Caml-list] Test coverage of generated lexers/parsers

Hello,

Does somebody have experience measuring test coverage of generated
lexers/parsers?

I'm using ocamllex/ocamlyacc [1] (but I can switch to Menhir [2]) to
generate a lexer/parser. In my tests, I simply check that some input
strings give the ASTs I expect.

I usually use Bisect [3] to make sure that my tests cover the code I
intended to cover, but in that configuration, Bisect is lost between the
.mll/.mly files and the generated .ml files and produces useless reports.

How would you measure test coverage in that case?

Thanks,
