Abstract: In recent years, the scale and complexity of embedded software have increased sharply. Especially in the fields of national defense, rail transit, automobile, civil aviation and industrial control, users have stricter requirements on the quality of embedded software, and their tolerance for defects of embedded software has become lower and lower. Therefore, how to effectively improve the quality of embedded software becomes an urgent problem to be solved. Taking the air conditioning control module of a new energy vehicle control strategy as an example, this paper analyzes how the black box test technologies such as equivalence class partition method, boundary value analysis method and cause and effect diagram method are integrated and applied in the design of embedded software test cases; it expounds the organic integration of different black box test methods, which can effectively and orderly design a group of functional test cases with high reliability and strong execution, thus improving the test efficiency and ensuring the test confidence and software quality.
