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