Test2::Formatter \- Namespace for formatters.

.IX Header "DESCRIPTION"
This is the namespace for formatters. This is an empty package.

.IX Header "CREATING FORMATTERS"
A formatter is any package or object with a \f(CW\*(C`write($event, $num)\*(C'\fR method.
.PP

\& package Test2::Formatter::Foo;
\& use strict;
\& use warnings;
\&
\& sub write {
\& my $self_or_class = shift;
\& my ($event, $assert_num) = @_;

.PP
The \f(CW\*(C`write\*(C'\fR method is a method, so it either gets a class or instance. The two
arguments are the \f(CW$event\fR object it should record, and the \f(CW$assert_num\fR
which is the number of the current assertion (ok), or the last assertion if
this even is not itself an assertion. The assertion number may be any integer 0
or greater, and may be undefined in some cases.
.PP
The \f(CW\*(C`hide_buffered()\*(C'\fR method must return a boolean. This is used to tell
buffered subtests whether or not to send it events as they are being buffered.
See \*(L"run_subtest(...)\*(R" in Test2::API for more information.
.PP
The \f(CW\*(C`terminate\*(C'\fR and \f(CW\*(C`finalize\*(C'\fR methods are optional methods called that you
can implement if the format you're generating needs to handle these cases, for
example if you are generating \s-1XML\s0 and need close open tags.
.PP
The \f(CW\*(C`terminate\*(C'\fR method is called when an event's \f(CW\*(C`terminate\*(C'\fR method returns
true, for example when a Test2::Event::Plan has a \f(CW\*(Aqskip_all\*(Aq\fR plan, or
when a Test2::Event::Bail event is sent. The \f(CW\*(C`terminate\*(C'\fR method is passed
a single argument, the Test2::Event object which triggered the terminate.
.PP
The \f(CW\*(C`finalize\*(C'\fR method is always the last thing called on the formatter, \fIexcept when \f(CI\*(C`terminate\*(C'\fI is called for a Bail event\fR. It is passed the
following arguments:
.IP "\(bu" 4
The number of tests that were planned
.IP "\(bu" 4
The number of tests actually seen
.IP "\(bu" 4
The number of tests which failed
.IP "\(bu" 4
A boolean indicating whether or not the test suite passed
.IP "\(bu" 4
A boolean indicating whether or not this call is for a subtest
