# [NAME](#NAME)

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

# [DESCRIPTION](#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](#SYNOPSIS)

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

# [ENVIRONMENT VARIABLES](#ENVIRONMENT_VARIABLES)

[T2\_KEEP\_TEMPDIR=0](#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'](#T2_TEMPDIR_TEMPLATE=)

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_ALSO)
