Bug #44596 for Test-WWW-Mechanize:

put_ok is broken : accoding to documentation, put_ok should accept similar options as WWW::Mechanize's put, but as a hash reference. So the following should succeed : $mech->put_ok( $url, { content => 'foo' }, $description); But the content is not sent in the request. Indeed in Test::WWW::Mechanize, line 366 : $self->put( $url, \%opts ); should be : $self->put( $url, %opts ); ( According to WW::Mechanize, the syntaxe is : $mech->put( $uri, content => $content );
