计算机系统验证涉及的测试
Tests involved in computer system verification
根据系统风险、复杂性和新颖性的不同，测试也分为不同的层级。对于简单低风险的系统而言（不可配置系统），可以采用单层级的测试，但是对于复杂的可配置系统或者定制系统，应该采用多层级的测试。
According to the system risk, complexity and novelty, the test is also divided into different levels. For simple and low risk systems (non configurable systems), single-level testing can be used, but for complex configurable systems or customized systems, multi-level testing should be used.
计算机系统不同阶段的测试包括：
Tests at different stages of the computer system include:
