=head1 NAME

Test::Alien::Run - Run object

=head1 VERSION

version 2.48

=head1 SYNOPSIS

 use Test2::V0;
 use Test::Alien;
 
 run_ok([ $^X, -e => 'print "some output"; exit 22'])
   ->exit_is(22)
   ->out_like(qr{some});

=head1 DESCRIPTION

This class stores information about a process run as performed by
L<Test::Alien#run_ok>.  That function is the I<ONLY> way to create
an instance of this class.

=head1 ATTRIBUTES

=head2 out

 my $str = $run->out;

The standard output from the run.

=head2 err

 my $str = $run->err;

The standard error from the run.

=head2 exit

 my $int = $run->exit;

The exit value of the run.

=head2 signal

 my $int = $run->signal;

The signal that killed the run, or zero if the process was terminated normally.

=head1 METHODS

These methods return the run object itself, so they can be chained,
as in the synopsis above.

=head2 success

 $run->success;
 $run->success($message);

Passes if the process terminated normally with an exit value of 0.

=head2 exit_is

 $run->exit_is($exit);
 $run->exit_is($exit, $message);

Passes if the process terminated with the given exit value.

=head2 exit_isnt

 $run->exit_isnt($exit);
 $run->exit_isnt($exit, $message);

Passes if the process terminated with an exit value of anything
but the given value.

=head2 out_like

 $run->out_like($regex);
 $run->out_like($regex, $message);

Passes if the output of the run matches the given pattern.

=head2 out_unlike

 $run->out_unlike($regex);
 $run->out_unlike($regex, $message);

Passes if the output of the run does not match the given pattern.

=head2 err_like

 $run->err_like($regex);
 $run->err_like($regex, $message);

Passes if the standard error of the run matches the given pattern.

=head2 err_unlike

 $run->err_unlike($regex);
 $run->err_unlike($regex, $message);

Passes if the standard error of the run does not match the given pattern.

=head2 note

 $run->note;

Send the output and standard error as test note.

=head2 diag

 $run->diag;

Send the output and standard error as test diagnostic.
