difference between stress testing and loadtesting

Answer Posted / subbu malepati

Stress testing is subjecting a system to an unreasonable
load while denying it the resources (e.g., RAM, disc, mips,
interrupts, etc.) needed to process that load. The idea is
to stress a system to the breaking point in order to find
bugs that will make that break potentially harmful. The
system is not expected to process the overload without
adequate resources, but to behave (e.g., fail) in a decent
manner (e.g., not corrupting or losing data). Bugs and
failure modes discovered under stress testing may or may
not be repaired depending on the application, the failure
mode, consequences, etc. The load (incoming transaction
stream) in stress testing is often deliberately distorted so
as to force the system into resource depletion.

Load testing is subjecting a system to a statistically
representative (usually) load. The two main reasons for
using such loads is in support of software reliability
testing and in performance testing. The term "load testing"
by itself is too vague and imprecise to warrant use. For
example, do you mean representative load," "overload," "high
load," etc. In performance testing, load is
varied from a minimum (zero) to the maximum level the system
can sustain without running out of resources or having,
transactions >suffer (application-specific) excessive delay.

A third use of the term is as a test whose objective is to
determine the maximum sustainable load the system can
handle. In this usage, "load testing" is merely testing at
the highest transaction arrival rate in performance testing.
