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, 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 cannot be found (or L 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 The constructor returns a new C object. If L is not installed, returns undef. =cut # new() implementation supplied by TAP::Object sub _initialize { my $self = shift; if ($NO_COLOR) { # shorten that message a bit ( my $error = $NO_COLOR ) =~ s/ in \@INC .*//s; warn "Note: Cannot run tests in color: $error\n"; return; # abort object construction } return $self; } ############################################################################## =head3 C Test::Formatter::Color->can_color() Returns a boolean indicating whether or not this module can actually generate colored output. This will be false if it could not load the modules needed for the current platform. =cut sub can_color { return !$NO_COLOR; } =head3 C Set the output color. =cut 1;
