# Test2::IPC::Driver::Files(3perl)

Temp dir + Files concurrency model.

## NAME

Test2::IPC::Driver::Files - Temp dir + Files concurrency model.

## DESCRIPTION

This is the default, and fallback concurrency model for Test2. This sends events between processes and threads using serialized files in a temporary directory. This is not particularly fast, but it works everywhere.

## SYNOPSIS

```
    use Test2::IPC::Driver::Files;
    # IPC is now enabled
```

## ENVIRONMENT VARIABLES

- T2\_KEEP\_TEMPDIR=0

  When true, the tempdir used by the IPC driver will not be deleted when the test is done.

- T2\_TEMPDIR\_TEMPLATE='test2-XXXXXX'

  This can be used to set the template for the IPC temp dir. The template should follow template specifications from File::Temp.

## SEE ALSO

See Test2::IPC::Driver for methods.
