1. A method for testing a portable electronic device, the portable electronic device including an acquisition member, a processing unit including a cache memory, a first storage unit and a display screen,
wherein the method comprises the following steps:
acquiring a set of parameters including at least one parameter via the acquisition member;
storing the set of parameters in a first area of the first storage unit;
storing the set of parameters in a second area of the first storage unit, the second area being separate from the first area;
generating at least one first image representative of a first set of results including at least one first result, the first set of results being generated by the application, by the processing unit, of a first processing operation based on the set of parameters stored in the first area of the first storage unit;
in a first displaying step, displaying the at least one first image on the display screen for a first predetermined time period;
in a first erasing step, erasing first intermediate results corresponding to calculation steps carried out during the first processing operation, the first intermediate results being erased from the cache memory of the processing unit;
generating at least one second image representative of a second set of results including at least one second result, the second set of results being generated by the application, by the processing unit, of a second processing operation based on the set of parameters stored in the second area of the first storage unit, the first set of results and the second set of results being equal except in the event of loss of integrity of the portable electronic device; and
in a second displaying step, displaying the at least one second image on the display screen for a second predetermined time period.
