What's the difference between load and stress testing?

[Bobby]

Hi,



Load Testing and Stress testing refers to performance,both are same



but differ as.....Load refers to the no of users to check the performance



irrespective of time...where as the stress is defined as the testing done



at the uninterval peak loads.....





What i answered is right but not in the right terminilogy.

Anyway check it out.

hello



herez ur answer





One of the most common, but
unfortunate misuse of terminology is treating "load testing" and
"stress testing" as synonymous. The consequence of this ignorant
semantic abuse is usually that the system is neither properly "load
tested" nor subjected to a meaningful stress test.



1. 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.



2. 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.

Hi ur answer is...


The execution of your application under predetermined level of resources under load is termed as Laod Testing.


The Execution of your application under predetermined level of resources under un-interval peak loads is termed as Stress Testing.

Hi
Load and Stress test both helps to test the ability of the application to perform while under load. During the Stress test we attempt to stress an aspect of the system to the point of failure – Our goal is being to determine the weak points in the system architecture. During the Load test we can identify the peak load conditions at which the program will fail to handle required processing loads within required time spans

Hi Everyone,


For definitions and information, one can also check wikipedia.com


It is not that I do not want to give information myself, but the person requiring info can always remember them if we can give the links so that they can get the info themselves.
