Technical Data Sheet


The Open Group has expanded it's range of test suites for the latest IEEE POSIX® Realtime amendments. This is an opportunity for leading real-time suppliers to acquire state-of-the-art test tools to ensure the development of conformant POSIX® Realtime products.

The Open Group is well established as the premier open systems test supplier and certification authority. As a supplier independent and product neutral organization, The Open Group is the logical choice in developing standards-based test suites and certification schemes.



The Open Group has a portfolio of test suites that cover the complete POSIX 1003.1-1996 standard, including POSIX 1003.1b (realtime) and POSIX 1003.1c (threads), to include the latest POSIX Realtime amendments (1003.1d, 1003.1j and 1003.1q) and POSIX 1003.13-1998 Profiles 52 and 54 (more . . .). In addition tests are also available for POSIX 1003.1, 2003 Edition.

Use of test suites is essential for proper development and maintenance of standards-based products, ensuring conformance of supplier products to industry-standard APIs, application portability and interoperability. In-depth testing with Open Group test suites identifies defects at the earliest possible point in the development and test cycle minimizing costly defects found in the field.


The POSIX Realtime Test Suites

The POSIX Realtime Test Suites includes tests for

  • IEEE POSIX 1003.1b-1993/1003.1i-1995 Realtime extension and IEEE POSIX 1003.1,2003 Edition (VSRT)
  • IEEE Std POSIX 1003.1c-1995 Threads (pthreads) extension and IEEE POSIX 1003.1,2003 Edition(VSTH)
  • IEEE POSIX 1003.1d-1999 Additional Realtime Extension and IEEE POSIX 1003.1,2003 Edition (VSRTE)
  • IEEE POSIX 1003.1j-2000 Advanced Realtime Extension and IEEE POSIX 1003.1,2003 Edition(VSART)
  • IEEE POSIX 1003.1q-2000 Trace and IEEE POSIX 1003.1,2003 Editio and IEEE POSIX 1003.1,2003 Edition (VSTRC)
  • IEEE POSIX 1003.13-1998 Profile 52 (VSPSE52)
  • IEEE POSIX 1003.13-1998 Profile 54 (VSPSE54)

These test suites have been developed as test packages under the Test Environment Toolkit and the VSXgen test framework, allowing them to be run stand-alone, or combined with other relevant VSXgen test packages.
