UPSTREAM: abs01: Switch from <values.h> to <limits.h>

The <values.h> is an obsolete glibc interface that wraps <limits.h> and
<float.h>. The abs01 test only uses it for MININT, which can be
switched over to <limits.h> and INT_MIN, for increased portability.

Linux Test Project

Linux Test Project is a joint project started by SGI, OSDL and Bull developed and maintained by IBM, Cisco, Fujitsu, SUSE, Red Hat, Oracle and others. The project goal is to deliver tests to the open source community that validate the reliability, robustness, and stability of Linux.

The LTP testsuite contains a collection of tools for testing the Linux kernel and related features. Our goal is to improve the Linux kernel and system libraries by bringing test automation to the testing effort. Interested open source contributors are encouraged to join.

Project pages are located at: http://linux-test-project.github.io/

The latest image is always available at: https://github.com/linux-test-project/ltp/releases

The discussion about the project happens at ltp mailing list: http://lists.linux.it/listinfo/ltp

The git repository is located at GitHub at: https://github.com/linux-test-project/ltp

Warning!

Be careful with these tests!

Don't run them on production systems. Growfiles, doio, and iogen in particular stress the I/O capabilities of systems and while they should not cause problems on properly functioning systems, they are intended to find (or cause) problems.

Quick guide to running the tests

If you have git, autoconf, automake, m4, the linux headers and the common developer packages installed, the chances are the following will work.

$ git clone https://github.com/linux-test-project/ltp.git
$ cd ltp
$ make autotools
$ ./configure
$ make
$ make install

This will install LTP to /opt/ltp.

  • If you have a problem see doc/mini-howto-building-ltp-from-git.txt.
  • If you still have a problem see INSTALL and ./configure --help.
  • Failing that, ask for help on the mailing list or Github.

Some tests will be disabled if the configure script can not find their build dependencies.

  • If a test returns TCONF due to a missing component, check the ./configure output.
  • If a tests fails due to a missing user or group, see the Quick Start section of INSTALL.

To run all the test suites

$ cd /opt/ltp
$ ./runltp

Note that many test cases have to be executed as root.

To run a particular test suite

$ ./runltp -f syscalls

To run all tests with madvise in the name

$ ./runltp -f syscalls -s madvise

Also see

$ ./runltp --help

Test suites (e.g. syscalls) are defined in the runtest directory. Each file contains a list of test cases in a simple format, see doc/ltp-run-files.txt.

Each test case has its own executable or script, these can be executed directly

$ testcases/bin/abort01

Some have arguments

$ testcases/bin/fork13 -i 37

The vast majority of test cases accept the -h (help) switch

$ testcases/bin/ioctl01 -h

Many require certain environment variables to be set

$ LTPROOT=/opt/ltp PATH="$PATH:$LTPROOT/testcases/bin" testcases/bin/wc01.sh

Most commonly, the path variable needs to be set and also LTPROOT, but there are a number of other variables, runltp usually sets these for you.

Note that all shell scripts need the PATH to be set. However this is not limited to shell scripts, many C based tests need environment variables as well.

Developers corner

Before you start you should read following documents:

  • doc/test-writing-guidelines.txt
  • doc/build-system-guide.txt

There is also a step-by-step tutorial:

  • doc/c-test-tutorial-simple.txt

If something is not covered there don't hesitate to ask on the LTP mailing list. Also note that these documents are available online at:
