```{index} single: TAP::Formatter::File::Session ``` # TAP::Formatter::File::Session Harness output delegate for file output ## VERSION Version 3.52 ## DESCRIPTION This provides file orientated output formatting for [TAP::Harness](../../Harness.md). It is particularly important when running with parallel tests, as it ensures that test results are not interleaved, even when run verbosely. ## METHODS ### result Stores results for later output, all together. ### close\_test When the test file finishes, outputs the summary, together.
