=head1 NAME
Test::Builder - Backend for building test libraries
=head1 SYNOPSIS
package My::Test::Module;
use Test::Builder;
require Exporter;
@ISA = qw(Exporter);
@EXPORT = qw(ok);
my $Test = Test::Builder->new;
$Test->output('my_logfile');
sub import {
my($self) = shift;
my $pack = caller;
$Test->exported_to($pack);

$self->export_to_level(1, $self, 'ok');
}
sub ok {
my($test, $name) = @_;
$Test->ok($test, $name);
}
=head1 DESCRIPTION
Test::Simple and Test::More have proven to be popular testing modules,
but they're not always flexible enough. Test::Builder provides the a
building block upon which to write your own test libraries I<which can
work together>.
=head2 Construction
=over 4
=item B<new>
my $Test = Test::Builder->new;
Returns a Test::Builder object representing the current state of the
test.
Since you only run one test per program, there is B<one and only one>
Test::Builder object. No matter how many times you call new(), you're
getting the same object. (This is called a singleton).

=head2 Setting up tests
These methods are for setting up tests and declaring how many there
are. You usually only want to call one of these methods.
=over 4
=item B<exported_to>
my $pack = $Test->exported_to;
$Test->exported_to($pack);
Tells Test::Builder what package you exported your functions to.
This is important for getting TODO tests right.

=item B<plan>
$Test->plan('no_plan');
$Test->plan( skip_all => $reason );
$Test->plan( tests => $num_tests );
A convenient way to set up your tests. Call this and Test::Builder
will print the appropriate headers and take the appropriate actions.
If you call plan(), don't call any of the other methods below.

Convenience method for building testing functions that take regular

Takes a quoted regular expression produced by qr//, or a string
representing a regular expression.
Returns a Perl value which may be used instead of the corresponding
regular expression, or undef if it's argument is not recognised.
For example, a version of like(), sans the useful diagnostic messages,
could be written as:

Most useful when you can't depend on the test output order, such as

Controlling where the test output goes.
It's ok for your test to change where STDOUT and STDERR point to,
Test::Builder's default output settings will not be affected.
=over 4
=item B<diag>
$Test->diag(@msgs);
Prints out the given $message. Normally, it uses the failure_output()
handle, but if this is for a TODO test, the todo_output() handle is
used.
Output will be indented and marked with a # so as not to interfere
with test output. A newline will be put on the end if there isn't one
already.
We encourage using this rather than calling print directly.
Returns false. Why? Because diag() is often used in conjunction with
a failing test (C<ok() || diag()>) it "passes through" the failure.
return ok(...) || diag(...);

details). Returns the reason (ie. the value of $TODO) if running as
todo tests, false otherwise.
todo() is pretty part about finding the right package to look for
$TODO in. It uses the exported_to() package to find it. If that's
not set, it's pretty good at guessing the right package to look at.
Sometimes there is some confusion about where todo() should be looking
for the $TODO variable. If you want to be sure, tell it explicitly

_my_exit($exit_num);
Perl seems to have some trouble with exiting inside an END block. 5.005_03
and 5.6.1 both seem to do odd things. Instead, this function edits $?
directly. It should ONLY be called from inside an END block. It
doesn't actually exit, that's your job.

# 5.004!

Looks like you failed $num_failed tests of $Expected_Tests.

Looks like your test died just after $Curr_Test.

=head1 THREADS
In perl 5.8.0 and later, Test::Builder is thread-safe. The test
number is shared amongst all threads. This means if one thread sets
the test number using current_test() they will all be effected.
=head1 EXAMPLES
CPAN can provide the best examples. Test::Simple, Test::More,
Test::Exception and Test::Differences all use Test::Builder.
