=head1 NAME

TAP::Parser::Result::Test - Test result token.

=head1 VERSION

Version 3.26

=cut

$VERSION = '3.26';

=head1 DESCRIPTION

This is a subclass of L<TAP::Parser::Result>. A token of this class will be
returned if a test line is encountered.

1..1
ok 1 - woo hooo!

=head1 OVERRIDDEN METHODS

This class is the workhorse of the L<TAP::Parser> system. Most TAP lines will
be test lines and if C<< $result->is_test >>, then you have a bunch of methods
at your disposal.

=head2 Instance Methods

=cut

##############################################################################

=head3 C<ok>

my $ok = $result->ok;

Returns the literal text of the C<ok> or C<not ok> status.

=cut

sub ok { shift->{ok} }

##############################################################################

=head3 C<number>

my $test_number = $result->number;

Returns the number of the test, even if the original TAP output did not supply
that number.

=cut

sub number { shift->{test_num} }

sub _number {
my ( $self, $number ) = @_;
$self->{test_num} = $number;
}

##############################################################################

=head3 C<description>

my $description = $result->description;

Returns the description of the test, if any. This is the portion after the
test number but before the directive.

=cut

sub description { shift->{description} }

##############################################################################

=head3 C<directive>

my $directive = $result->directive;

Returns either C<TODO> or C<SKIP> if either directive was present for a test
line.

=cut

sub directive { shift->{directive} }

##############################################################################

=head3 C<explanation>

my $explanation = $result->explanation;

If a test had either a C<TODO> or C<SKIP> directive, this method will return
the accompanying explanation, if present.

not ok 17 - 'Pigs can fly' # TODO not enough acid

For the above line, the explanation is I<not enough acid>.

=cut

sub explanation { shift->{explanation} }

##############################################################################

=head3 C<is_ok>

if ( $result->is_ok ) { ... }

Returns a boolean value indicating whether or not the test passed. Remember
that for TODO tests, the test always passes.

If the test is unplanned, this method will always return false. See
C<is_unplanned>.

=cut

sub is_ok {
my $self = shift;

return if $self->is_unplanned;

# TODO directives reverse the sense of a test.
return $self->has_todo ? 1 : $self->ok !~ /not/;
}

##############################################################################

=head3 C<is_actual_ok>

if ( $result->is_actual_ok ) { ... }

Returns a boolean value indicating whether or not the test passed, regardless
of its TODO status.

=cut

sub is_actual_ok {
my $self = shift;
return $self->{ok} !~ /not/;
}

##############################################################################

=head3 C<actual_passed>

Deprecated. Please use C<is_actual_ok> instead.

=cut

sub actual_passed {
warn 'actual_passed() is deprecated. Please use "is_actual_ok()"';
goto &is_actual_ok;
}

##############################################################################

=head3 C<todo_passed>

if ( $test->todo_passed ) {
# test unexpectedly succeeded
}

If this is a TODO test and an 'ok' line, this method returns true.
Otherwise, it will always return false (regardless of passing status on
non-todo tests).

This is used to track which tests unexpectedly succeeded.

=cut

sub todo_passed {
my $self = shift;
return $self->has_todo && $self->is_actual_ok;
}

##############################################################################

=head3 C<todo_failed>

# deprecated in favor of 'todo_passed'. This method was horribly misnamed.

This was a badly misnamed method. It indicates which TODO tests unexpectedly
succeeded. Will now issue a warning and call C<todo_passed>.

=cut

sub todo_failed {
warn 'todo_failed() is deprecated. Please use "todo_passed()"';
goto &todo_passed;
}

##############################################################################

=head3 C<has_skip>

if ( $result->has_skip ) { ... }

Returns a boolean value indicating whether or not this test has a SKIP
directive.

=head3 C<has_todo>

if ( $result->has_todo ) { ... }

Returns a boolean value indicating whether or not this test has a TODO
directive.

=head3 C<as_string>

print $result->as_string;

This method prints the test as a string. It will probably be similar, but
not necessarily identical, to the original test line. Directives are
capitalized, some whitespace may be trimmed and a test number will be added if
it was not present in the original line. If you need the original text of the
test line, use the C<raw> method.

=cut

sub as_string {
my $self = shift;
my $string = $self->ok . " " . $self->number;
if ( my $description = $self->description ) {
$string .= " $description";
}
if ( my $directive = $self->directive ) {
my $explanation = $self->explanation;
$string .= " # $directive $explanation";
}
return $string;
}

##############################################################################

=head3 C<is_unplanned>

if ( $test->is_unplanned ) { ... }
$test->is_unplanned(1);

If a test number is greater than the number of planned tests, this method will
return true. Unplanned tests will I<always> return false for C<is_ok>,
regardless of whether or not the test C<has_todo>.

Note that if tests have a trailing plan, it is not possible to set this
property for unplanned tests as we do not know it's unplanned until the plan
is reached:

print <<'END';
ok 1
ok 2
1..1
END

=cut

sub is_unplanned {
my $self = shift;
return ( $self->{unplanned} || '' ) unless @_;
$self->{unplanned} = !!shift;
return $self;
}
