初次接触LTP (Linux Test Project) 被LTP的各种man文件、LTP官网文档还有网上找的七七八八的文章搞得一头雾水,怎么都测试不成功,不知道是我英文太烂没理解对还是它写的不清楚。经过反复摸索终于成功了,现详述如下,还望各位看客不要嫌我写得罗嗦,希望对初次安装使用LTP测试套的人有所帮助。
一、下载LTP测试套
可以从http://sourceforge.net/projects/ltp/files/LTP Source/下载最新的LTP压缩包,如ltp-full-20110228.bz2
下载后建议存放到/home目录下,不要放在/root目录下,因为一些测试需要非root用户来完成。
解压、编译、安装:
1、tar jvxf ltp-full-20110228.bz2
2、cd ltp-full-20110228.bz2
3、./configure (此步可能不成功,则先执行make autotools,然后再./configure)
4、make
5、make install
注意:ltp 的默认安装路径是/opt/ltp,所以接下来的执行测试步骤都需要在/opt/ltp目录下完成(这个一定要特别注意,我当时就误到这了,在/home目录下折腾半天总是测试报错
FATAL: LTP not installed correctly
INFO: Follow directions in INSTALL!
原来不是安装错误,是进错文件夹了)
二、执行测试
当前有三个脚本可用于执行LTP测试套件,分别是runltp、networktests.sh以及diskio.sh。最常用的就是runltp脚本,它可用于执行LTP中绝大部分的测试(default set of tests,但是不包括networktests及diskio测试。
执行./runltp的一些选项参数如下(借用官网):
-a EMAIL_TO EMAIL all your Reports to this E-mail Address
-c NUM_PROCS Run LTP under additional background CPU load
[NUM_PROCS = no. of processes creating the CPU Load by spinning over sqrt()
(Defaults to 1 when value)]
-C FAILCMDFILE Command file with all failed test cases.
-d TMPDIR Directory where temporary files will be created.
-D NUM_PROCS,NUM_FILES,NUM_BYTES,CLEAN_FLAG
Run LTP under additional background Load on Secondary Storage (Seperate by comma)
[NUM_PROCS = no. of processes creating Storage Load by spinning over write()]
[NUM_FILES = Write() to these many files (Defaults to 1 when value 0 or undefined)]
[NUM_BYTES = write these many bytes (defaults to 1GB, when value 0 or undefined)]
[CLEAN_FLAG = unlink file to which random data written, when value 1]
-e Prints the date of the current LTP release
-f CMDFILES Execute user defined list of testcases (separate with ',')
-g HTMLFILE Create an additional HTML output format
-h Help. Prints all available options.
-i NUM_PROCS Run LTP under additional background Load on IO Bus
[NUM_PROCS = no. of processes creating IO Bus Load by spinning over sync()]
-l LOGFILE Log results of test in a logfile.
-m NUM_PROCS,CHUNKS,BYTES,HANGUP_FLAG
Run LTP under additional background Load on Main memory (Seperate by comma)
[NUM_PROCS = no. of processes creating main Memory Load by spinning over malloc()]
[CHUNKS = malloc these many chunks (default is 1 when value 0 or undefined)]
[BYTES = malloc CHUNKS of BYTES bytes (default is 256MB when value 0 or undefined) ]
[HANGUP_FLAG = hang in a sleep loop after memory allocated, when value 1]
-N Run all the networking tests.
-n Run LTP with network traffic in background.
-o OUTPUTFILE Redirect test output to a file.
-p Human readable format logfiles.
-q Print less verbose output to screen.
-r LTPROOT Fully qualified path where testsuite is installed.
-s PATTERN Only run test cases which match PATTERN.
-t DURATION Execute the testsuite for given duration. Examples:
-t 60s = 60 seconds
-t 45m = 45 minutes
-t 24h = 24 hours
-t 2d = 2 days
-T REPETITION Execute the testsuite for REPETITION no. of times
-v Print more verbose output to screen.
-w CMDFILEADDR Uses wget to get the user's list of testcases.
-x INSTANCES Run multiple instances of this testsuite.
执行LTP测试的方式主要有两种,一种是执行全部default set of tests, 另一种是执行user defined set of tests。
1、执行default set of tests
cd /opt/ltp (你所安装的ltp的存放目录,默认是/opt/ltp)
./runltp -p -l result.log
2、执行user defined set of tests
如果你只是想执行LTP中的一部分test cases,你可以按照如下步骤操作:
cd /opt/ltp/runtest
vim your_command_file (创建命令文件,当然也可以使用runtest目录中现有的命令文件)
命令文件由两部分组成,一是test case标签“tag",另一个是你希望执行的具体的"test case"脚本名以及一些参数。比如:
#Tag Test case
#---------------------------------------
mtest01 mtest01 -p 10
cgroup_fj run_cgroup_test_fj.sh
controllers test_controllers.sh
cpuctl_stress run_cpuctl_stress_test.sh 9
编辑结束后保存你的命令文件,执行
cd .. (退出runtest目录,回到/opt/ltp目录)
./runltp -p -l result.02.log -f your_command_file
大功告成,此时测试如果还会报错,那就可能是你的命令文件中参数设置不正确,可根据error提示去检查命令文件及相应的脚本文件,一些脚本文件可能需要特定的参数才能正确执行。
