Difference between Load Testing and the Stress testing

| Hi All,
Could you please provide me with the difference between Load Testing
and the Stress Testing and also the difference between Sytem Testing
and Functional testing.
Thanks in advance.

How about you take a guess and we help correct you?
(But understand we might make up an answer different from what your
interogator expects!!)

Hi Balaji,
Load testing is slowly adding load and depicting a real time scenario
with proper ramp-up, ramp-down of the users and Think time
Stress testing is done to depict a very unrealistic situation by adding
all the load at a time without any think time so as to stress the system
to a maximum level where it would crash. This is usually done to make
sure all the roll-back mechanism works properly.

| Note that Priyaplm's definition of load testing is ONE POSSIBLE
definition of load testing; and that the definition of stress testing
is ONE POSSIBLE definition of stress testing. If I'm doing a stress
test, I'm interested in seeing if the application stays up or falls
down; the roll-back mechanism may or may not be interesting to me
(there may or may not BE a roll-back mechanism).
In general load testing, for me, is about trying to run the application
with volumes of data or transactions that are intended to be in a range
from realistic to overwhelming. Stress testing, for me, is about
trying to run the application such that its resources (including but
not limited to disk, memory, simultaneous logins, database connections,
etc.) are constrained in some way. Note that load testing, for me, can
lead to stressful situations, and that in a stress test, I would
usually want to expose the application to significant loads, so there
is a grey area between load and stress testing.
As Phlip points out, anyone who is asking you about the difference has
something in mind, so when you answer, you should make it very clear
that your answer is subjective. If you're very brave, you can assert,
accurately, that their answer is subjective too. No one owns the
definitions of the terms; they're only applicable within someone's
context.
