Stress Testing Task

A Stress Testing Task is a system testing task that ...

• Context:
  • It can be used to determine breaking points or safe usage limits
  • It can be used to confirm mathematical model is accurate enough in predicting breaking points or safe usage limits
  • It can be used to confirm intended specifications are being met
  • It can be used to determine modes of failure (how exactly a system fails)
  • It can be used to test stable operation of a part or system outside standard usage.
  • ...
• Counter-Example(s):
  • Usability Testing.

  • Stress testing (sometimes called torture testing) is a form of deliberately intense or 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. 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.
