VSX4 + XNFS Overview

The X/Open Network File System Test Suite


  • Verifies the Network File System specification, including tests for system interfaces over NFS, and the NFS protocol itself.
  • Over 2000 tests.


The Network File System Verification Suite Release 4, known as VSX4+XNFS, has the following test modes:

  • XPG3 & XPG4. Either mode can be used for branding XNFS, although XPG4 mode performs additional testing of features that are not required by XNFS Issue 1.
  • For the Internet Server Brand, XNFS must be run in XPG4 mode.

VSX4+XNFS uses the distributed version of the standard Test Environment Toolkit (TETware) as its test harness. TETware, can be downloaded from the TETworks website.


Disk Space Requirements

Disk space requirements on a typical CISC based system are as follows:

Source Source + tests (built for XNFS testing)

  • Client 25 Mb 60 Mb
  • Server 2 Mb 20 Mb

Numbers of tests, and time to run

  • over 2000 tests

A typical test run from start to finish takes typically 2 hours.

Test Coverage

The VSX test suite verifies the compliance of systems to the Network File System Specification , including tests for system interfaces over a remote file system, and NFS protocol tests. Note that the version of the protocol tested by this suite is the Version 2 NFS protocol.
