pjdfstest学习
pjdfstest是什么？
使用perl的标准模块TAP::Harness进行脚本测试统计。
TAP::Harness-使用统计数据运行测试脚本。
这是一个简单的测试线束,它允许测试运行,结果自动汇总并输出到STDOUT。
执行的时候，使用prove，实际上prove就是一个perl脚本。
#!/usr/bin/perl -w
eval 'exec /usr/bin/perl -w -S $0 ${1+"$@"}'
if 0; # not running under some shell
use strict;
use App::Prove;
my $app = App::Prove->new;
$app->process_args(@ARGV);
exit( $app->run ? 0 : 1 );
__END__

prove - Run tests through a TAP harness.
=head1 USAGE
prove [options] [files or directories]
=head1 OPTIONS
Boolean options:
-v, --verbose Print all test lines.
-l, --lib Add 'lib' to the path for your tests (-Ilib).
-b, --blib Add 'blib/lib' and 'blib/arch' to the path for
your tests......
man一下prove，如下：
