Stress to test - Simulate cpu, memory, io load

How to stress test Linux? Just use stress command which is available from apt-get and probably other package managers as well. Here is how you can consume 500MB RAM for a period of 30 seconds.
$ stress --vm 1 --vm-bytes 500M -t 30s --vm-hang 30
stress: info: [7651] dispatching hogs: 0 cpu, 0 io, 1 vm, 0 hdd
Test up front, Quality assurance is the very first step to guarantee constant process improvement.
