=head1 NAME

Test::BDD::Cucumber::Executor - Run through Feature and Harness objects

=head1 VERSION

version 0.75

=head1 DESCRIPTION

The Executor runs through Features, matching up the Step Lines with Step
Definitions, and reporting on progress through the passed-in harness.

=head1 ATTRIBUTES

=head2 matching

The value of this attribute should be one of C<first> (default), C<relaxed> and C<strict>.

By default (C<first>), the first matching step is executed immediately,
terminating the search for (further) matching steps. When C<matching> is set
to anything other than C<first>, all steps are checked for matches. When set
to C<relaxed>, a warning will be generated on multiple matches. When set to
C<strict>, an exception will be thrown.

=cut

has matching => ( is => 'rw', isa => Str, default => 'first');

=head1 METHODS

=head2 extensions

=head2 add_extensions

The attributes C<extensions> is an arrayref of
L<Test::BDD::Cucumber::Extension> extensions. Extensions have their
hook-functions called by the Executor at specific points in the BDD feature
execution.

B<C<<add_extensions>> adds items in FIFO using unshift()>, and are called in
reverse order at the end hook; this means that if you:

  add_extensions( 1 );
  add_extensions( 2, 3 );

The C<pre_*> will be called in order 2, 3, 1, and C<post_*> will be called in
1, 3, 2.

=cut

has extensions => (
    is      => 'ro',
    isa     => ArrayRef,
    default => sub { [] },
    handles_via => 'Array',
    handles => { add_extensions => 'unshift' },
);

=head2 steps

=head2 add_steps

The attributes C<steps> is a hashref of arrayrefs, storing steps by their Verb.
C<add_steps()> takes step definitions of the item list form:

 (
  [ Given => qr//, sub {} ],
 ),

Or, when metadata is specified with the step, of the form:

 (
  [ Given => qr//, { meta => $data }, sub {} ]
 ),

(where the hashref stores step metadata) and populates C<steps> with them.

=cut

has 'steps' => ( is => 'rw', isa => HashRef, default => sub { {} } );

sub add_steps {
    my ( $self, @steps ) = @_;

    # Map the steps to be lower case...
    for (@steps) {
        my ( $verb, $match, $meta, $code );

        if (@$_ == 3) {
            ( $verb, $match, $code ) = @$_;
            $meta = {};
        }
        else {
            ( $verb, $match, $meta, $code ) = @$_;
        }
        $verb = lc $verb;

        unless ( ref($match) ) {
            $match =~ s/:\s*$//;
            $match = quotemeta($match);
            $match = qr/^$match:?/i;
        }

        if ( $verb eq 'transform' or $verb eq 'after' ) {

            # Most recently defined Transform takes precedence
            # and After blocks need to be run in reverse order
            unshift( @{ $self->{'steps'}->{$verb} }, [ $match, $meta, $code ] );
        } else {
            push( @{ $self->{'steps'}->{$verb} }, [ $match, $meta, $code ] );
        }

    }
}

=head2 execute

Execute accepts a feature object, a harness object, and an optional
L<Test::BDD::Cucumber::TagSpec> object and for each scenario in the
feature which meets the tag requirements (or all of them, if you
haven't specified one), runs C<execute_scenario>.

=cut

sub execute {
    my ( $self, $feature, $harness, $tag_spec ) = @_;
    my $feature_stash = {};

    $harness->feature($feature);
    my @background =

    # Get all scenarios
    my @scenarios = @{ $feature->scenarios() };

    $_->pre_feature( $feature, $feature_stash ) for @{ $self->extensions };
    for my $outline (@scenarios) {

                scenario      => $outline,

        );
    }
    $_->post_feature( $feature, $feature_stash, 'no' )
      for reverse @{ $self->extensions };

    $harness->feature_done($feature);
}

=head2 execute_outline

Accepts a hashref of options and executes each scenario definition in the
scenario outline, or, lacking an outline, executes the single defined
scenario.

Options:

C< feature > - A L<Test::BDD::Cucumber::Model::Feature> object

C< feature_stash > - A hashref that should live the lifetime of
 feature execution

C< harness > - A L<Test::BDD::Cucumber::Harness> subclass object

C< outline > - A L<Test::BDD::Cucumber::Model::Scenario> object

C< background > - An optional L<Test::BDD::Cucumber::Model::Scenario> object
representing the Background

C<background_obj> - An optional L<Test::BDD::Cucumber::Model::Scenario> object
representing the Background

C<scenario_stash> - A hashref that lives the lifetime of the scenario execution

For each step, a L<Test::BDD::Cucumber::StepContext> object is created, and
passed to C<dispatch()>. Nothing is returned - everything is played back through
the Harness interface.
