1LTP User Guidelines 2=================== 3 4For compiling, installing and running the tests see `README.md`. 5For running LTP network tests see `testcases/network/README.md`. 6 71. Library environment variables 8-------------------------------- 9 10|============================================================================== 11| 'KCONFIG_PATH' | The path to the kernel config file, (if not set, it tries 12 the usual paths '/boot/config-RELEASE' or '/proc/config.gz'). 13| 'KCONFIG_SKIP_CHECK' | Skip kernel config check if variable set (not set by default). 14| 'LTPROOT' | Prefix for installed LTP, the default is '/opt/ltp'. 15| 'LTP_COLORIZE_OUTPUT' | Force colorized output behaviour. 'y' or '1': always colorize 16 'n' or '0': never colorize. 17| 'LTP_DEV' | Path to the block device to be used 18 (C: '.needs_device = 1', shell: 'TST_NEEDS_DEVICE=1'). 19| 'LTP_SINGLE_FS_TYPE' | Testing only - specifies filesystem instead all 20 supported (for tests with '.all_filesystems'). 21| 'LTP_DEV_FS_TYPE' | Filesystem used for testing (default: 'ext2'). 22| 'LTP_TIMEOUT_MUL' | Multiply timeout, must be number >= 1 (> 1 is useful for 23 slow machines to avoid unexpected timeout). 24 Variable is also used in shell tests, but ceiled to int. 25| 'LTP_VIRT_OVERRIDE' | Overrides virtual machine detection in the test 26 library. Setting it to empty string tell the library 27 that system is not a virtual machine. Other possible 28 values are 'kvm', 'xen', 'zvm' and 'microsoft' that 29 describe different types supervisors. 30| 'PATH' | It's required to addjust path: 31 `PATH="$PATH:$LTPROOT/testcases/bin"` 32| 'TMPDIR' | Base directory for template directory (C: '.needs_tmpdir = 1' 33 and others, which imply it, shell: 'TST_NEEDS_TMPDIR=1'). 34| 'TST_NO_CLEANUP' | Disable running test cleanup (defined in 'TST_CLEANUP'). 35|============================================================================== 36 372. Colorized output 38------------------- 39 40By default LTP colorizes it's output unless using pipe or redirect to file. 41It's possible to force behaviour with 'LTP_COLORIZE_OUTPUT' environment variable. 42
