       Test2::Manual::Testing::Todo - Tutorial for marking tests as TODO.

DESCRIPTION

       This tutorial covers the process of marking tests as TODO. It also describes how TODO works under the
       hood.

THE TOOL

           use Test2::Tools::Basic qw/todo/;

   TODO BLOCK
       This form is low-magic. All tests inside the block are marked as todo, tests outside the block are not
       todo. You do not need to do any variable management.  The flaw with this form is that it adds a couple
       levels to the stack, which can break some high-magic tests.

       Overall this is the preferred form unless you have a special case that requires the variable form.

           todo "Reason for the todo" => sub {
               ok(0, "fail but todo");
               ...
           };

   TODO VARIABLE
       This form maintains the todo scope for the life of the variable. This is useful for tests that are
       sensitive to scope changes. This closely emulates the Test::More style which localized the $TODO package
       variable. Once the variable is destroyed (set it to undef, scope end, etc) the TODO state ends.

           my $todo = todo "Reason for the todo";
           ok(0, "fail but todo");
           ...
           $todo = undef;

MANUAL TODO EVENTS

           use Test2::API qw/context/;

           sub todo_ok {
               my ($bool, $name, $todo) = @_;

               my $ctx = context();
               $ctx->send_event('Ok', pass => $bool, effective_pass => 1, todo => $todo);
               $ctx->release;

               return $bool;
           }

       The Test2::Event::Ok event has a "todo" field which should have the todo reason. The event also has the
       "pass" and "effective_pass" fields. The "pass" field is the actual pass/fail value. The "effective_pass"
       is used to determine if the event is an actual failure (should always be set tot true with todo).

HOW THE TODO TOOLS WORK UNDER THE HOOD

       The Test2::Todo library gets the current Test2::Hub instance and adds a filter. The filter that is added
       will set the todo and effective pass fields on any Test2::Event::Ok events that pass through the hub. The
       filter also converts Test2::Event::Diag events into Test2::Event::Note events.
