NAME

Test::Lazy::Template

SYNOPSIS

Build a template for running a similar set of tests repeatedly.

The purpose of this module is to provide a convenient way of testing a set of initial conditions in different ways.

The best way to show this is in an example:

        # Template up the intial condition template.
        my $template = new Test::Lazy::Template([ 
                [ "qw/1/" ],
                [ "qw/a/" ],
                [ "qw/apple/" ],
                [ "qw/2/" ],
                [ "qw/0/" ],
                [ "qw/-1/" ],
                [ "map { \$_ => \$_ * 2 } qw/0 1 2 3 4/" ],
        ]);

        # Run some different tests.
        # NOTE: Don't have to use '%?' if the statement will run without modification.
        $template->test("defined(%?)" => ok => undef);
        $template->test("length(%?) >= 1" => ok => undef);
        $template->test("length(%?)" => '>=' => 1);
        $template->test("length(%?)" => '<' => 10);
        $template->test([
                [ '%?' => is => 1 ],
                [ is => 'a' ],
                [ is => 'apple' ],
                [ is => 2 ],
                [ is => 0 ],
                [ is => is => -1 ],
                [ is => { 0 => 0, 1 => 2, 2 => 4, 3 => 6, 4 => 8 } ],
        ]);

METHODS

Test::Lazy::Template->new( <template> )

Test::Lazy::Template->new( <test>, <test>, ..., <test> )

Create a new "Test::Lazy::Template" object using the giving test specification.

If <template> is a SCALAR reference, then new will split <template> on each newline, ignoring empty lines and lines beginning with a pound (#).

                # You could do something like this:
                my $template = template(\<<_END_);
        qw/1/
        qw/a/
        qw/apple/
        qw/2/
        qw/0/
        qw/-1/

        # Let's test this one too.
        map { \$_ => \$_ * 2 } qw/0 1 2 3 4/
        _END_

Returns the new "Test::Lazy::Template" object

$template->test( <template> )

For each test in $template, modify and run each the test according to the corresponding entry in <template>.

$template->test( <test> )

Modify and then run each test in $template by using <test> to complete each test's specification.
