       Test::Block - DEPRECIATED: Specify fine granularity test plans


         use Test::More 'no_plan';
         use Test::Block qw($Plan);

             # This block should run exactly two tests
             local $Plan = 2;
             pass 'first test';
             # oops. forgot second test

         SKIP: {
             local $Plan = 3;
             pass('first test in second block');
             skip "skip remaining tests" => $Plan;

         ok( Test::Block->all_in_block, 'all test run in blocks' );
         is( Test::Block->block_count, 2, 'two blocks ran' );

         # This produces...

         ok 1 - first test
         not ok 2 - block expected 2 test(s) and ran 1
         #     Failed test ( at line 6)
         ok 3 - first test in second block
         ok 4 # skip skip remaining tests
         ok 5 # skip skip remaining tests
         ok 6 - all test run in blocks
         ok 7 - two blocks ran
         # Looks like you failed 1 tests of 7.


       NOTE: This module was written before subtests existed in TAP and Test::More. These days
       subtests will probably be a better option for you.

       This module allows you to specify the number of expected tests at a finer level of
       granularity than an entire test script. It is built with Test::Builder and plays happily
       with Test::More and friends.

       If you are not already familiar with Test::More now would be the time to go take a look.

   Creating test blocks
       Test::Block supplies a special variable $Plan that you can localize to specify the number
       of tests in a block like this:

           use Test::More 'no_plan';
           use Test::Block qw($Plan);

               local $Plan = 2;
               pass('first test');
               pass('second test');

   What if the block runs a different number of tests?
       If a block doesn't run the number of tests specified in $Plan then Test::Block will
       automatically produce a failing test. For example:

               local $Plan = 2;
               pass('first test');
               # oops - forgot second test

       will output

           ok 1 - first test
           not ok 2 - block 1 expected 2 test(s) and ran 1

   Tracking the number of remaining tests
       During the execution of a block $Plan will contain the number of remaining tests that are
       expected to run so:

               local $Plan = 2;
               diag "$Plan tests to run";
               pass('first test');
               diag "$Plan tests to run";
               pass('second test');
               diag "$Plan tests to run";

       will produce

           # 2 tests to run
           ok 1 - first test
           # 1 tests to run
           ok 2 - second test
           # 0 tests to run

       This can make skip blocks easier to write and maintain, for example:

           SKIP: {
               local $Plan = 5;
               pass('first test');
               pass('second test');
               skip "debug tests" => $Plan unless DEBUG > 0;
               pass('third test');
               pass('fourth test');
               skip "high level debug tests" => $Plan unless DEBUG > 2;
               pass('fifth test');

   Named blocks
       To make debugging easier you can give your blocks an optional name like this:

               local $Plan = { example => 2 };
               pass('first test');
               # oops - forgot second test

       which would output

           ok 1 - first test
           not ok 2 - block example expected 2 test(s) and ran 1

   Test::Block objects
       The $Plan is implemented using a tied variable that stores and retrieves Test::Block
       objects. If you want to avoid the tied interface you can use Test::Block objects directly.

             # create a block expecting 4 tests
             my $block = Test::Block->plan(4);

             # create a named block with two tests
             my $block = Test::Block->plan('test name' => 2);

           You create Test::Block objects with the "plan" method. When the object is destroyed it
           outputs a failing test if the expected number of tests have not run.

           You can find out the number of remaining tests in the block by calling the "remaining"
           method on the object.

           Test::Block objects overload "" and "0+" to return the result of the remaining method.

           Returns Test::Builder object used by Test::Block. For example:

             Test::Block->builder->skip('skip a test');

           See Test::Builder for more information.

           A class method that returns the number of blocks that have been created. You can use
           this to check that the expected number of blocks have run by doing something like:

             is( Test::Block->block_count, 5, 'five blocks run' );

           at the end of your test script.

           Returns true if all tests so far run have been inside the scope of a Test::Block

             ok( Test::Block->all_in_block, 'all tests run in blocks' );

       Thanks to chromatic and Michael G Schwern for the excellent Test::Builder, without which
       this module wouldn't be possible.
