```{index} single: Test2::IPC::Driver::Files ``` # Test2::IPC::Driver::Files Temp dir + Files concurrency model. ## DESCRIPTION This is the default, and fallback concurrency model for [Test2](../../../Test2.md). This sends events between processes and threads using serialized files in a temporary directory. This is not particularly fast, but it works everywhere. ## SYNOPSIS ```perl 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](../../../File/Temp.md). ## SEE ALSO See [Test2::IPC::Driver](../Driver.md) for methods. ## SOURCE The source code repository for Test2 can be found at [https://github.com/Test-More/test-more/](https://github.com/Test-More/test-more/). ## MAINTAINERS - Chad Granum ## AUTHORS - Chad Granum ## COPYRIGHT Copyright Chad Granum .
