Abstract: With the continuous development of information technology, smart home, especially smart home scenes, has become more and more popular in people's family life, people have higher requirements for smart home scenes, when users use scenarios, their functional defects seriously affect the experience. In the process of scenario function testing, there are some situations of imperfect test dimensions and unscientific case design. To improve the quality of scene function test in smart home industry. Proposes a method to improve scenario test dimensions and scientifically design test cases, and takes the home-coming scenario as an example, the analysis fully considers the completeness, correctness, suitability and compliance of functions in the process of functional testing, and integrates scenario method, equivalence class division method, boundary value analysis method and other technologies into the process of designing test cases in an orderly and efficient manner. Illustrates the method of scenario function test case design, 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 confidence of smart home scenario function and software quality.

Key words: Smart home, Scene test, Function test, Use case design, Equivalence class division
