  • 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.

    • 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. [1]

      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.
