'N/A' : ( row.x / row.y ) %] [% END -%] [% END %]

3. 2008-06-18 davidrw Concepts & Methodology • Key Concepts • Coverage of TT templates • Unit tests on TT templates • Issues • Coverage of .ttc, not tmpl itself • Uncoverable TT-generated code • TODO • Gather Feedback! • Review & test TT hooks, overloads, subclassing • Ensure robustness over hacks Interface use Devel::Cover::TT qw{ -silent 1 -ignore . }; # Devel::Cover::TT::* Provider, Document Approach BEFORE Cache file contents: Template::Document->new( .... ); To read from cache: $foo = require $cachefile AFTER Cache file contents: package path::to:tmpl::example_tmpl.pm; sub getDocument { Template::Document->new( .... ); } 1; To read from cache: eval { use path::to:tmpl::example_tmpl; $foo = path::to:tmpl::example_tmpl->getDocument(); }

4. 2008-06-18 davidrw Analysis & Improved Coverage! { title => 'Test2', subtitle => 'second test', verbose => 1, rows => [ { x => 1, y => 2, }, { x => 3, y => 0, }, { x => 2, y => 4, }, ], }; && rows.size > 0
