In order to test the software cheating behavior of electronic scale in the market,and a set of software automatic simulation testing system of electronic scale was put forward. Hardware device of software simulation testing system was built,machine vision system was used for electronic scale character recognition. Voltage was used for quality simulation. Relays were used for key-press simulation. And automatic simulation testing system software was written with VC ＋＋. Series of experiments were carried out for different electronic scale. The results show that the system can be used for software testing in the electronic scale,which can detect the software cheating problem. The good results in the experiments of different electronic scales show the stability and the generality of the system.
