NAME
Test2::Formatter - Namespace for formatters.
DESCRIPTION
This is the namespace for formatters. This is an empty package.
CREATING FORMATTERS
A formatter is any package or object with a "write($event, $num)"
method.
package Test2::Formatter::Foo;
use strict;
use warnings;
sub write {
my $self_or_class = shift;
my ($event, $assert_num) = @_;
...
}
sub hide_buffered { 1 }
sub terminate { }
sub finalize { }
sub supports_tables { return $BOOL }
sub new_root {
my $class = shift;
...
$class->new(@_);
}
1;
The "write" method is a method, so it either gets a class or instance.
The two arguments are the $event object it should record, and the
$assert_num which is the number of the current assertion (ok), or the
last assertion if this event is not itself an assertion. The assertion
number may be any integer 0 or greater, and may be undefined in some
cases.
The "hide_buffered()" method must return a boolean. This is used to
tell buffered subtests whether or not to send it events as they are
being buffered. See "run_subtest(...)" in Test2::API for more
information.
The "terminate" and "finalize" methods are optional methods called that
you can implement if the format you're generating needs to handle these
cases, for example if you are generating XML and need close open tags.
The "terminate" method is called when an event's "terminate" method
returns true, for example when a Test2::Event::Plan has a 'skip_all'
plan, or when a Test2::Event::Bail event is sent. The "terminate"
method is passed a single argument, the Test2::Event object which
triggered the terminate.
The "finalize" method is always the last thing called on the formatter,
except when "terminate" is called for a Bail event. It is passed the
following arguments:
The "supports_tables" method should be true if the formatter supports
directly rendering table data from the "info" facets. This is a newer
feature and many older formatters may not support it. When not
supported the formatter falls back to rendering "detail" instead of the
"table" data.
The "new_root" method is used when constructing a root formatter. The
default is to just delegate to the regular "new()" method, most
formatters can ignore this.
o The number of tests that were planned
o The number of tests actually seen
o The number of tests which failed
o A boolean indicating whether or not the test suite passed
o A boolean indicating whether or not this call is for a subtest
The "new_root" method is called when "Test2::API::Stack" Initializes
the root hub for the first time. Most formatters will simply have this
call "$class->new", which is the default behavior. Some formatters
however may want to take extra action during construction of the root
formatter, this is where they can do that.
