What (who) is stress testing - definition

Stress test; Biological stress testing

stress testing

<testing> Testing aimed at investigating the behaviour of a software or hardware equipment in out of ordinary operating conditions. (1998-03-27)

Stress testing (software)

SOFTWARE TESTING ACTIVITY THAT DETERMINES THE ROBUSTNESS OF SOFTWARE BY TESTING BEYOND THE LIMITS OF NORMAL OPERATION

Stress test (software); Software stress test; Software stress testing

Stress testing is a software testing activity that determines the robustness of software by testing beyond the limits of normal operation. Stress testing is particularly important for "mission critical" software, but is used for all types of software.

Hardware stress test

SEVERE TEST FOR SAFETY AND PERFORMANCE OF HARDWARE

Stress test (hardware); Hardware stress testing

A stress test (sometimes called a torture test) of hardware is a form of deliberately intense and thorough testing used to determine the stability of a given system or entity. It involves testing beyond normal operational capacity, often to a breaking point, in order to observe the results.

Wikipedia

Stress testing

Stress testing is a form of deliberately intense or thorough testing, used to determine the stability of a given system, critical infrastructure or entity. It involves testing beyond normal operational capacity, often to a breaking point, in order to observe the results.

Reasons can include:

to determine breaking points or safe usage limits
to confirm mathematical model is accurate enough in predicting breaking points or safe usage limits
to confirm intended specifications are being met
to determine modes of failure (how exactly a system fails)
to test stable operation of a part or system outside standard usage

Reliability engineers often test items under expected stress or even under accelerated stress in order to determine the operating life of the item or to determine modes of failure.

The term "stress" may have a more specific meaning in certain industries, such as material sciences, and therefore stress testing may sometimes have a technical meaning – one example is in fatigue testing for materials.

In animal biology, there are various forms of biological stress and biological stress testing, such as the cardiac stress test in humans, often administered for biomedical reasons. In exercise physiology, training zones are often determined in relation to metabolic stress protocols, quantifying energy production, oxygen uptake, or blood chemistry regimes.

Examples of use of stress testing

1. It is not a great recommendation for the stress testing of such systems and the reliability of online banking.

2. And he urged senior managers to make sure they understand the real risk they‘re carrying in their portfolios, by conducting tougher "what if" stress testing.

3. Mr Topping said the HKMA was the first Asian regulator to propose the use of sophisticated modelling and stress testing methods.

4. Earlier this year, the HKMA conducted an extensive stress–testing exercise that modelled the impact of a sudden rise in interest rates âЂ« of more than 2 per cent âЂ« on individual banks, based on data derived from regulatory inspections.

5. When it does filter through there is likely to be "a significant stress–testing of the still relatively benign interaction between the US economy and higher energy prices," he added.
