=head1 NAME

App::Prove::State - State storage for the C<prove> command.

=head1 VERSION

Version 3.17_01

=cut

$VERSION = '3.17_01';

=head1 DESCRIPTION

The C<prove> command supports a C<--state> option that instructs it to
store persistent state across runs. This module implements that state
and the operations that may be performed on it.

=head1 SYNOPSIS

# Re-run failed tests
$ prove --state=fail,save -rbv

=cut

=head1 METHODS

=head2 Class Methods

=head3 C<new>

Accepts a hashref with the following key/value pairs:

=over 4

=item * C<store>

The filename of the data store holding the data that App::Prove::State reads.

=item * C<extension> (optional)

The test name extension. Defaults to C<.t>.

=item * C<result_class> (optional)

The name of the C<result_class>. Defaults to C<App::Prove::State::Result>.

=back

=cut

sub new {
    my $class = shift;
    my %args = %{ shift || {} };

    my $self = bless {
        select => [],
        seq => 1,
        store => delete $args{store},
        extension => ( delete $args{extension} || '.t' ),
        result_class =>
          ( delete $args{result_class} || 'App::Prove::State::Result' ),
    }, $class;

    $self->{_} = $self->result_class->new(
        { tests => {},
            generation => 1,
        }
    );
    my $store = $self->{store};
    $self->load($store)
      if defined $store && -f $store;

    return $self;
}

=head2 C<result_class>

Getter/setter for the name of the class used for tracking test results. This
class should either subclass from C<App::Prove::State::Result> or provide an
identical interface.

=cut

=head2 C<extension>

Get or set the extension files must have in order to be considered
tests. Defaults to '.t'.

=cut

sub extension {
    my $self = shift;
    $self->{extension} = shift if @_;
    return $self->{extension};
}

=head2 C<results>

Get the results of the last test run. Returns a C<result_class()> instance.

=cut

sub results {
    my $self = shift;
    $self->{_} || $self->result_class->new;
}

=head2 C<commit>

Save the test results. Should be called after all tests have run.

=cut

sub commit {
    my $self = shift;
    if ( $self->{should_save} ) {
        $self->save;
    }
}

=head2 Instance Methods

=head3 C<apply_switch>

$self->apply_switch('failed,save');

Apply a list of switch options to the state, updating the internal
object state as a result. Nothing is returned.

Diagnostics:
- "Illegal state option: %s"

=over

=item C<last>

Run in the same order as last time

=item C<failed>

Run only the failed tests from last time

=item C<passed>

Run only the passed tests from last time

=item C<all>

Run all tests in normal order

=item C<hot>

Run the tests that most recently failed first

=item C<todo>

Run the tests ordered by number of todos.

=item C<slow>

Run the tests in slowest to fastest order.

=item C<fast>

Run test tests in fastest to slowest order.

=item C<new>

Run the tests in newest to oldest order.

=item C<old>

Run the tests in oldest to newest order.

=item C<save>

Save the state on exit.
