.SH NAME
Test2::Tools::Defer \- Write tests that get executed at a later time
.SH DESCRIPTION
.IX Header "DESCRIPTION"
Sometimes you need to test things BEFORE loading the necessary functions. This
module lets you do that. You can write tests, and then have them run later,
after \f(CW\*(C`Test2\*(C'\fR is loaded. You tell it what test function to run, and what
arguments to give it.  The function name and arguments will be stored to be
executed later. When ready, run \f(CWdo_def()\fR to kick them off once the functions
are defined.
.SH SYNOPSIS

.Vb 2

\&    use Test2::Tools::Defer;

.SH EXPORTS
.IX Header "EXPORTS"
.ie n .IP "def function => @args;" 4
.el .IP "def function => \f(CW@args\fR;" 4
.IX Item "def function => @args;"
This will store the function name, and the arguments to be run later. Note that
each package has a separate store of tests to run.
.IP \fBdo_def()\fR 4
.IX Item "do_def()"
This will run all the stored tests. It will also reset the list to be empty so
you can add more tests to run even later.
