# DBD::Gofer::Transport::null - phpMan

## 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.
