=head1 NAME
TAP::Formatter::Color - Run Perl test scripts with color
=head1 VERSION
Version 3.28
=cut
$VERSION = '3.28';
=head1 DESCRIPTION
Note that this harness is I<experimental>. You may not like the colors I've
chosen and I haven't yet provided an easy way to override them.
This test harness is the same as L<TAP::Harness>, but test results are output
in color. Passing tests are printed in green. Failing tests are in red.
Skipped tests are blue on a white background and TODO tests are printed in
white.
If L<Term::ANSIColor> cannot be found (or L<Win32::Console> if running
under Windows) tests will be run without color.
=head1 SYNOPSIS
use TAP::Formatter::Color;
my $harness = TAP::Formatter::Color->new( \%args );
$harness->runtests(@tests);
=head1 METHODS
=head2 Class Methods
=head3 C<new>
The constructor returns a new C<TAP::Formatter::Color> object. If
L<Term::ANSIColor> is not installed, returns undef.

# new() implementation supplied by TAP::Object

=head3 C<can_color>
Test::Formatter::Color->can_color()
Returns a boolean indicating whether or not this module can actually
generate colored output. This will be false if it could not load the
modules needed for the current platform.
=cut
sub can_color {
return !$NO_COLOR;
}
=head3 C<set_color>
Set the output color.
