libwww-mechanize-formfiller-perl binary package in Ubuntu Xenial amd64

 WWW::Mechanize::FormFiller is intended as a simple way to fill out HTML forms
 from a set of predetermined values. You set up the form filler with value
 elements, retrieve the HTML form, and let the form filler loose on that form.
 .
 There are value classes provided for many tasks - fixed values, values
 to be queried interactively from the user, values taken randomly from
 a list of values and values specified through a callback to some Perl code.
