Stress testing is a procedure used to determine the stability and robustness of a system or entity. It involves testing the specific system or entity to beyond its normal operational capacity, often to a breaking point, in order to observe its performance/reaction to a pre-defined internal or external pressure or force. Stress tests have been used for many years in air traffic safety, in particular for airplanes and helicopters. In recent years, stress testing has often been associated with methodologies to assess the vulnerability of a financial system or specific components of it, such as banks. A number of analytical tools have been developed in this area and have been frequently used since the late 1990s (e.g. Borio et al., 2012). However, stress testing has also been criticized in the field of forecasting due to the use of historical data taken from periods of time that are considered to be insufficient for reliable predictions.

With stress testing, the load placed on the system is increased beyond the normal expected usage to test the applications response. Either the load on the user pattern may be increased or the system may be executed continuously for a lengthy period of time (hours or days) to test the robustness of the hardware system under stress.

The current international standard IEC 62366-1 [26] of MT development only considers two assessment dimensions: risk and usability. Currently, stressors are assessed within a technical process known as ‘stress testing’ [57] usually applied by manufactures to test software or hardware at extreme and high pressured conditions. There are two levels to this stress-testing: (i) the technical analysis of the device’s components and (ii) the risk assessment within hazard-related scenarios as recommended by ISO 14971 [58] which defines best practice of risk management throughout a MT’s life cycle [26].
