```{index} single: DBD::Gofer::Transport::null ``` # DBD::Gofer::Transport::null DBD::Gofer client transport for testing ## SYNOPSIS ```perl my $original_dsn = "..." DBI->connect("dbi:Gofer:transport=null;dsn=$original_dsn",...) ``` or, enable by setting the DBI\_AUTOPROXY environment variable: ```text export DBI_AUTOPROXY="dbi:Gofer:transport=null" ``` ## 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 `dbi:Gofer:transport=null` 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 `t/85gofer.t` script in the DBI distribution includes a comparative benchmark. ## AUTHOR Tim Bunce, [http://www.tim.bunce.name](http://www.tim.bunce.name) ## LICENCE AND COPYRIGHT Copyright (c) 2007, Tim Bunce, Ireland.
