The POSIX Test Suite is a free (as in speech) test suite with the goal of performing conformance, functional, and stress testing of the IEEE 1003.1-2001 System Interfaces specification in a manner that is agnostic to any given implementation.

This package only provides the test suite results in a log file. If you want to run the testsuite, use the source package of the same name (e.g. apt-get source posixtestsuite).
