=head1 NAME

DBD::Gofer::Transport::null - DBD::Gofer client transport for testing

=head1 SYNOPSIS

  my $original_dsn = &quot;...&quot;
  DBI-&gt;connect(&quot;dbi:Gofer:transport=null;dsn=$original_dsn&quot;,...)

or, enable by setting the DBI_AUTOPROXY environment variable:

  export DBI_AUTOPROXY=&quot;dbi:Gofer:transport=null&quot;

=head1 DESCRIPTION

Connect via DBD::Gofer but execute the requests within the same process.

This is a quick and simple way to test applications for compatibility with the
(few) restrictions that DBD::Gofer imposes.

It also provides a simple, portable way for the DBI test suite to be used to
test DBD::Gofer on all platforms with no setup.

Also, by measuring the difference in performance between normal connections and
connections via C&lt;dbi:Gofer:transport=null&gt; the basic cost of using DBD::Gofer
can be measured. Furthermore, the additional cost of more advanced transports can be
isolated by comparing their performance with the null transport.

The C&lt;t/85gofer.t&gt; script in the DBI distribution includes a comparative benchmark.
