=head1 NAME
Parrot::Configure::Test - subroutines used in F<t/configure/*> tests
=head1 SYNOPSIS
use lib qw( lib );
use Parrot::Configure::Test qw( test_step_thru_runstep );
Set-up for C<test_step_thru_runstep()>:
$parrot_version = Parrot::BuildUtil::parrot_version();
$args = process_options( {
argv => [ ],
script => $0,
parrot_version => $parrot_version,
} );
$conf = Parrot::Configure->new;
test_step_thru_runstep($conf, q{init::defaults}, $args);
=head1 DESCRIPTION
The subroutines in this package are used to simplify tests found in
F<t/configure/>. Any subroutine in this package should be functional
(C<i.e.>, not object-oriented), be exported only on demand and have all its
arguments explicitly passed as arguments.
=head1 FUNCTIONS
=head2 C<test_step_thru_runstep()>
=over 4
=item * Purpose
Reduce code repeated in many test files in the F<t/configure/101+> series.
Execution of certain configuration steps depends upon successful
execution of some (though not necessarily all) of the preceding configuration
steps. Hence, unit tests of the packages generating certain steps may require
execution of preceding steps in the test file. Once you determine that you
need to execute one step as a prerequisite to another, you can provide that
step as an argument to C<test_step_thru_runstep()> and not worry about it
further.
=item * Arguments
List of three arguments:
=over 4
=item *
Parrot::Configure object
=item *
string holding the name of the step to be run
=item *
hash reference which is the output of
C<Parrot::Configure::Options::process_options()>.
=back
=item * Return Value
Returns the step number, but currently this is not used and needs
further exploration.
=item * Comment
Each invocation of C<test_step_thru_runstep()> runs 4 Test::More tests.
