=head1 NAME
Test::FITesque::Test - A FITesque test
=head1 SYNOPSIS
my $test = Test::FITesque::Test->new();
# add test rows
$test->add( ... );
$test->add( ... );
# return number of TAP tests
$test->test_count();
$test->run_tests();
=head1 DESCRIPTION
=head1 METHODS
=head2 new
my $test = Test::FITesque::Test->new();
This is a simple constructor. It takes a hashref of options:
=over
=item data
This is an arrayref of arrayrefs for the FITesque run.
=back
Please note that the first test row that is added must be the FITesque fixture
class name, followed by the arguments to be passed to its constructor.
=cut
sub new {
my ($class, $args) = @_;
$args ||= {};
my $self = bless $args, $class;
return $self;
}
=head2 add
$test->add(qw(Foo::Fixture some constructor args));
$test->add('click button', 'search');
This method allows you to add FITesque test rows individually. As with the data
option in the constructor, the first row added must be the Fixture class name
and its constructor arguments.
=cut
sub add {
my ($self, @args) = @_;
$self->{data} ||= [];
push @{ $self->{data} }, [@args];
}
=head2 test_count
my $count = $test->test_count();
This method returns the number of TAP tests expected to be run during the
test run.
=cut
sub test_count {
my ($self) = @_;
my $data = $self->{data} || [];
if(@$data){
my ($fixture_class) = $self->_load_fixture_class();
my $count = 0;
for my $test_row ( @$data[ 1..( scalar(@$data) -1) ]){
my $method_string = $test_row->[0];
my $test_count = $fixture_class->method_test_count($method_string) || 0;
$count += $test_count;
}
return $count;
}
return 0;
}
=head2 run_tests
$test->run_tests();
This method will run the FITesque test based upon the data supplied.
=cut
sub run_tests {
my ($self) = @_;
my $data = $self->{data} || [];
if(@$data){
