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


  my $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.
