.SH NAME
Test2::Tools \- Documentation for Tools.
.SH DESCRIPTION
.IX Header "DESCRIPTION"
Tools are packages that export test functions, typically all related to a
specific aspect of testing. If you have a couple different categories of
exports then you may want to break them into separate modules.
.PP
Tools should export testing functions. Loading tools \fBshould not\fR have side\-
effects, or alter the behavior of other tools. If you want to alter behaviors
or create side\-effects then you probably want to write a Test2::Plugin.
.SH FAQ
.IX Header "FAQ"
.IP "Why is it called Test2::Tools, and not Test2::Tool?" 4
.IX Item "Why is it called Test2::Tools, and not Test2::Tool?"
This question arises since Tools is the only namespace in the plural. This is
because each Plugin should be a distinct unit of functionality, but a Tools
dist can (and usually should) export several tools. A bundle is also typically
described as a single unit. Nobody would like Test2::Bundles::Foo.
.IP "Should my tools subclass Test2::Tools?" 4
.IX Item "Should my tools subclass Test2::Tools?"
No. Currently this class is empty. Eventually we may want to add behavior, in
which case we do not want anyone to already be subclassing it.
.SH "HOW DO I WRITE A \*(AqTOOLS\*(Aq MODULE?"
.IX Header "HOW DO I WRITE A 'TOOLS' MODULE?"
It is very easy to write tools:
.PP
.Vb 3
\&    package Test2::Tools::Mine
\&    use strict;
\&    use warnings;
\&
\&    # All tools should use the context() function.
\&    use Test2::API qw/context/;
\&
\&    our @EXPORTS = qw/ok plan/;
\&    use base \*(AqExporter\*(Aq;
\&
\&    sub ok($;$) {
\&        my ($bool, $name) = @_;
\&
\&        # All tool functions should start by grabbing a context
\&        my $ctx = context();
\&
\&        # The context is the primary interface for generating events
\&        $ctx\->ok($bool, $name);
\&
\&        # When you are done you release the context
\&        $ctx\->release;
\&
\&        return $bool ? 1 : 0;
\&    }
\&
