Research on Key Test Methods of the Smart Meter Software Based on Failure Modes

Software quality has become a key factor affecting the overall quality of the smart meter. To improve the reliability of the smart meter software, analyzed the typical failure modes and mechanism based on actual failure cases of smart meters. For different software failure modes, the test techniques were studied from the perspective of the software development cycle. Designed a test program of the smart meter software and provided automated test tools to improve the breadth and depth of the software test and improve the product reliability.
