When the control program is changed, the correctness of the control program needs to be verified before the mass production of the refrigerator.
At present, a method for testing refrigerator control software generally comprises the steps of building a whole set of refrigerator control system, namely connecting a refrigerator main control board and related electric device loads together, and simulating the temperature change in a refrigerator by using a variable resistance box. In the testing process, a tester needs to manually adjust the numerical value of the variable resistance box and then observe whether the load control of the main control board on each electric device is correct. According to the testing method, the whole process needs manual participation, and a testing tool needs to be set up, so that the testing efficiency is low.
For example, patent CN200710046974.3 discloses an automatic software testing system and method for an electronic refrigerator. The tested main control board of the test system needs to be installed on the whole refrigerator, and software test is carried out through actual operation of the whole refrigerator.
