DBD::Gofer::Transport::null(3)
NAME
DBD::Gofer::Transport::null - DBD::Gofer client transport for testing
SYNOPSIS
my $original_dsn = "..."
DBI->connect("dbi:Gofer:transport=null;dsn=$original_dsn",...)
or, enable by setting the DBI_AUTOPROXY environment variable:
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.
