A system for testing a negative pressure wound dressing, includes a simulated wound having a housing and a wound cavity within the housing, and having a shape and dimension representative of an actual wound type, a wound dressing positionable at least over the simulated wound, a negative pressure source in fluid communication with the wound cavity, at least one sensor adapted to record at least one parameter within the simulated wound, an air leak model including a valve in fluid communication with the wound cavity whereby opening of the valve simulates an air leak within the wound cavity, a fluid source in fluid communication with the wound cavity for delivering fluid to the wound cavity to simulate presence of exudates and a computer coupled to the at least one sensor for recording and analyzing data recorded by the at least one sensor to thereby providing an indication of functioning of the system.
