Linux Desktop Testing Project 1.4.0 (Default branch)
Linux Desktop Testing Project is aimed at producing a high quality test automation framework and cutting-edge tools that can be used to test the GNU desktop and improve it. It uses the "Accessibility" libraries to poke through the application's user interface. The framework also has tools to record test-cases based on user-selection on the application.License: GNU Lesser General Public License (LGPL)Changes:
A new API and performance enhancements. The LDTP editor now supports a configuration file for settings.Image

PING_PONG(1)						   CTDB - clustered TDB database					      PING_PONG(1)

NAME

       ping_pong - measures the ping-pong byte range lock latency

SYNOPSIS

       ping_pong {-r | -w | -rw} [-m] [-c] {FILENAME} {NUM-LOCKS}

DESCRIPTION

       ping_pong measures the byte range lock latency. It is especially useful on a cluster of nodes sharing a common lock manager as it will give
       some indication of the lock manager's performance under stress.

       FILENAME is a file on shared storage to use for byte range locking tests.

       NUM-LOCKS is the number of byte range locks, so needs to be (strictly) greater than the number of nodes in the cluster.

OPTIONS

       -r
	   test read performance

       -w
	   test write performance

       -m
	   use mmap

       -c
	   validate the locks

EXAMPLES

       Testing lock coherence

		 ping_pong test.dat N

       Testing lock coherence with lock validation

		 ping_pong -c test.dat N

       Testing IO coherence

		 ping_pong -rw test.dat N
