# DBD::Gofer::Transport::null(3pm)

DBD::Gofer client transport for testing

## 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.
