## NAME
    [DBD::Gofer::Transport::null](https://www.chedong.com/phpMan.php/perldoc/DBD%3A%3AGofer%3A%3ATransport%3A%3Anull/markdown) - [DBD::Gofer](https://www.chedong.com/phpMan.php/perldoc/DBD%3A%3AGofer/markdown) 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](https://www.chedong.com/phpMan.php/perldoc/DBD%3A%3AGofer/markdown) 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](https://www.chedong.com/phpMan.php/perldoc/DBD%3A%3AGofer/markdown) imposes.

    It also provides a simple, portable way for the DBI test suite to be used to test [DBD::Gofer](https://www.chedong.com/phpMan.php/perldoc/DBD%3A%3AGofer/markdown) 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](https://www.chedong.com/phpMan.php/perldoc/DBD%3A%3AGofer/markdown) 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.
