The purpose of the master's thesis is to present the process of developing a test system for testing a manufactured electronic circuit intended for installation in dishwashers. The developed system consists of a designed electronic circuit, based on a bed of nails principle, a testee (an electronic circuit for installation in dishwashers) and a user interface. Based on the initial analysis of the testee scheme and simulations, we designed an electronic circuit for carrying out the tests. The designed electronic circuit will enable us to detect the correct operation of triac outputs, relay outputs, motor rotation and many other functions. The communication between the designed circuit and the user interface is via USB communication. As part of the product, we developed three pieces of software, including programs on built-in microcontrollers and a user interface on a personal computer. Microcontroller programs take care of performing measurements and send results to the user interface, which allows us to manage measured results and present them more easily. The developed system enables the execution of a functional test of the testee's high-power side and displays the results.
