Testing process model and classification of test methods for embedded software of electrical products

As the development of science and technology, intelligent electrical appliances are increasing, gradually introducing the embedded microprocessor software to replace hardware to complete the functional and safe control has become an inevitable trend. As the electrical use is directly related to the safety of persons and property, so the safety testing and reliability testing of software are especially important. Compared with ordinary embedded software, embedded software of appliances has their own characteristics. Combination with general-purpose embedded software testing process improved V model and Butterfly model, this paper proposes the test process model for embedded software of electrical products based on their own software characteristics and further a study for classification of the test methods.
