Subrata Modak writes “The Linux Test Project test suite has been released for the month of May 2007. The latest version of the testsuite contains 2900+ tests for the Linux OS and can be found at http://prdownloads.sourceforge.net/ltp/ltp-full-20070531.tgz?download. Our web site also contains other information such as:

– A Linux test tools matrix

– Technical papers

– How To’s on Linux testing

– Code coverage analysis tool.

Release Highlights:

* Addition of ‘inotify’ syscall testcase(s) by

* KDUMP and UTSNAMESPACE testcases(s) maturing with more community contribution

* Removal of Invalid Testcase(s) “alarm04” & “sig_rev”

* Fixing of “su01_s1”, “gethostid01” and “swapon02” testcases

* Fixing wrong usage of “pthread_exit” and other thread APIs

* Correction of “Checksums” for “ipc_stress” testcases

* Gcov-Kernel Patches for linux-2.6.18, 2.6.19, 2.6.20 & 2.6.21

* Closing down long existing LTP Bugs

Note(s) from the Maintainer:

* Following are the important Highlights of Different Linux Kernel Releases. The Latest release of LTP testsuite package does not cover functionality/regression testcases of any of those new functionalities introduced. Hence, we request active contribution of new testcases from community members to cover all those functionalities:
