.IX Header "DESCRIPTION"
Connect via DBD::Gofer but execute the requests within the same process.
.PP
This is a quick and simple way to test applications for compatibility with the
(few) restrictions that DBD::Gofer imposes.
.PP
It also provides a simple, portable way for the \s-1DBI\s0 test suite to be used to
test DBD::Gofer on all platforms with no setup.
.PP
Also, by measuring the difference in performance between normal connections and
connections via \f(CW\*(C`dbi:Gofer:transport=null\*(C'\fR 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.
.PP
The \f(CW\*(C`t/85gofer.t\*(C'\fR script in the \s-1DBI\s0 distribution includes a comparative benchmark.
