1.Introduction

This Linux stress test tool is tested on Ubuntu, and support following test items:
*Hard disk/USB device read/write test
*Sytem suspend and resume test
*System hibernate and resume test
*System restart test

2.preparation

install fio

to use apt-get install command from ubuntu repositories in China, you must choose a repositories source that is not blocked

software & updating -> choose to download from china mirror site -> update repositories  

then you can install fio test tool

apt-get install fio

enable hibernate using swapfile

ubuntu create a default swapfile in root path when system is installed
It's recommanded to resize the swapfile to the size of RAM, for example, if your RAM size is 4GB

swapoff /swapfile  
dd if=/dev/zero of=/swapfile bs=1024M count=4  
chmod 600 /swapfile  
mkswap /swapfile  
swapon /swapfile  

to hibernate and resume from swapfile, you must config grub file of device UUID and offset and size of swapfile.
use df -h to find your filesystem name, use blkid to find corresponding UUID value, use filefrag –v /swapfile to find physical offset of swapfile finally,modify /etc/default/grub as following GRUB_CMDLINE_LINUX_DEFAULT="quiet splash resume=UUID=your_UUID resume_offset=your_physical_offset" then update grub, and restart PC update-grub

disable updates and set auto-login

for S5(restart) test, unexpected updates may cause S5 fail to wakeup, and auto-login is necessary too
disable updates:
gedit /etc/apt/apt.conf.d/20auto-upgrades, set all values to 0

set auto-login:
gedit /usr/share/lightdm/lightdm.conf.d/50-ubuntu.conf

user-session=ubuntu  
autologin-user=yourUserName  

gedit /etc/gdm3/custom.conf

AutomaticLoginEnable = true  
AutomaticLogin = yourUserName  

3.run scripts

all script is recommanded to run at /home/yourUserName

run fio

./fio_start.sh

stop fio

./fio_stop.sh

run S3/S4

./s3s4.sh option loops_you_need, for example:

./s3s4.sh s3 999

./s3s4.sh s4 999

stop S3/S4

just turn off terminal

run S5

./s5_start.sh

stop S5

./s5_stop.sh

logs

all logs are stored at log folder in script path in OPTION_DATA.log format
