Safety test has an important impact on the suspension management system, this paper starts from the top-level requirements of the product under test, according to the functional performance characteristics of the suspension management system, to identify possible factors affecting safety, design-related tests to verify, so as to improve product safety. Based on the definition of weapon security of suspension management system, based on the existing demand analysis model and theoretical methods to extract the top requirements of suspension management system and product safety design requirements, combined with the actual project testing experience, build a suspension management system weapon security demand analysis method, Combined with specific test project analysis of the actual use scenario of the product under test, testers can use this analysis template to quickly identify the key safety-related events in the product under test, form specific test requirements and design test cases.
