NAME

Test::Flatten - subtest output to a flatten

SYNOPSIS

in t/foo.t

  use Test::More;
  use Test::Flatten;
  
  subtest 'foo' => sub {
      pass 'OK';
  };
  
  subtest 'bar' => sub {
      pass 'ok';
      subtest 'baz' => sub {
          pass 'ok';
      };
  };
  
  done_testing;

run it

  $ prove -lvc t/foo.t
  t/foo.t .. 
  # ------------------------------------------------------------------------------
  # foo
  # ------------------------------------------------------------------------------
  ok 1 - ok
  # ------------------------------------------------------------------------------
  # bar
  # ------------------------------------------------------------------------------
  ok 2 - ok
  # ------------------------------------------------------------------------------
  # baz
  # ------------------------------------------------------------------------------
  ok 3 - ok
  1..3
  ok

oh, flatten!

DESCRIPTION

Test::Flatten is override Test::More::subtest.

The subtest I think there are some problems.

1. Caption is appears at end of subtest block.
  use Test::More;
  
  subtest 'foo' => sub {
      pass 'ok';
  };
  
  done_testing;
  
  # ok 1 - foo is end of subtest block.
  t/foo.t .. 
      ok 1 - ok
      1..1
  ok 1 - foo
  1..1
  ok

I want FIRST.

2. Summarizes the test would count.
  use Test::More;
  
  subtest 'foo' => sub {
      pass 'bar';
      pass 'baz';
  };
  
  done_testing;
  
  # total tests is 1
  t/foo.t .. 
      ok 1 - bar
      ok 2 - baz
      1..2
  ok 1 - foo
  1..1

I want 2.

3. Forked test output will be broken. (Even with Test::SharedFork!)
  use Test::More;
  
  subtest 'foo' => sub {
      pass 'parent one';
      pass 'parent two';
      my $pid = fork;
      unless ($pid) {
          pass 'child one';
          pass 'child two';
          fail 'child three';
          exit;
      }
      wait;
      pass 'parent three';
  };
  
  done_testing;
  
  # success...?
  t/foo.t .. 
      ok 1 - parent one
      ok 2 - parent two
      ok 3 - child one
      ok 4 - child two
      not ok 5 - child three
      
      #   Failed test 'child three'
      #   at t/foo.t line 13.
      ok 3 - parent three
      1..3
  ok 1 - foo
  1..1
  ok

oh, really? I want FAIL and sync count.

Yes, We can!!

FUNCTIONS

subtest($name, \&code)

This like Test::More::subtest.

SUBTEST_FILTER

If you need, you can using SUBTEST_FILTER environment. This is just a *hack* to skip only blocks matched the block name by environment variable. SUBTEST_FILTER variable can use regexp

  $ env SUBTEST_FILTER=foo prove -lvc t/bar.t
  # SKIP: bar by SUBTEST_FILTER
  # ------------------------------------------------------------------------------
  # foo
  # ------------------------------------------------------------------------------
  ok 1 - passed
  # SKIP: baz by SUBTEST_FILTER
  1..1
