.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 'TOOLS' 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 $bool ? 1 : 0;
\&    }
\&
\&    sub plan {
\&        my ($max) = @_;
\&        my $ctx = context();
\&        $ctx\->plan($max);
\&        $ctx\->release;
\&    }
\&
\&    1;
