Load testing -Load testing is a test whose objective is to
determine the maximum sustainable load the system can
handle. 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.

Stress testing - Stress testing is subjecting a system to
an unreasonable load while denying it the resources (e.g.,
RAM, disc, mips, interrupts) 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). The
load (incoming transaction stream) in stress testing is
often deliberately distorted so as to force the system into
resource depletion.

Performance testing - Validates that both the online
response time and batch run times meet the defined
performance requirements.

Answer / ditpti surve

load testing:- testing an application under heavy loads,
such as testing of a web site under a range of loads to
determine at what point the system's response time degrades
or fails.

performance testing:- testing to ensure that the application
responds in the time limit set by the user. if this is
needed, the client must supply the benchmarks to measure by
& we must have a hardware environment that mirrors production.

stress testing:- subject the system to extreme pressures in
a short time-span is stress testing.

Answer / balu

Load Testing : to check the performence of an application
based on increasing no.of vusers.

Stress Testing : to check the performence of an application
based on increasing no.of resources.

Performence Testing : To check whether our application is
giving response with in the expected time or not.

if any wrong make me to know.

Answer / madhuri

The execution of a software under customer expected
configured environment and customer expected load to
estimate speed of processing is called as load testing.

The execution of a software under customer expected
configured environment and customer expected load
continously to estimate longuity or durability called as
endurance testing.

The execution of a software under customer expected
configured environment and more customer load to
estimate peak load(maximum load) called as stress testing.

Performance testing = load testing+endurance testing+stress
testing

Answer / d.rajamannar

Performance testing

Combination of load and stress is known as performance testing.
Load testing

By increasing the number of user the system performance
should not affect.
Stress Testing

Checking UN estimated condition.By increasing the number of
user what time the system point degrades.

Answer / ramachandra naidu

Load Testing:
-------------
--> It is the process of creating demand on a system or
device and measuring its response.
--> It generally refers to the practice of modelling the
expected usage of a software program by simulating multiple
users accessing the program's services concurrently.
Performance testing:
-------------------
--> Validates that both the online response time and batch
run times meet the defined Performance requirements.
Stress Testing:
---------------
--> Testing conducted to evaluate a system or component at
or beyond the limits of its specified requirements to
determine the load under which it fails and how.
--> Often this is performance testing using a very high
level of simulated load.

Answer / anitha

Performance testing is testing that is performed to
determine how fast some aspect of a system performs under a
particular workload.

Answer / antony samy

Load testing is testing an application under heavy loads it
measurements stability and responsiveness through put the
application.

Stress testing is How heavy a load the application.


Performance testing check whether our application is
giving response with in the expected time or not.

Answer / anurajjagadale

Perforamnce Testing- test how application is performing under perticular situation. eg. how much time it will take to laod a webpage of perticular website
Load Testing:- Used to test yhe behaviour of application under specific laod.eg. application used by 100 user at a time.
Stress Testing:- Used to test the breaking point of application under extreme load and how that application recovers back from that situation. eg. application is used b 10k user at time.

Answer / mfsi_priyankaa

LOAD TESTING- It determines the maximum sustainable load the
system can handle.

PERFORMANCE TESTING-Performance testing can refer to the
assessment of the performance of a human examinee. For
example, a behind-the-wheel driving test is a performance
test of whether a person is able to perform the functions of
a competent driver of an automobile.

STRESS TESTING-It determines the breaking point of the
system i.e the point where the system crashes.

iam new to testing ,i want improve knowledge on manual and how to improve theoretically r practical?any one give me suggestion?
