正确答案
解析
变更请求(CR)用于记录和追踪缺陷、扩展请求和任何其他类型的产品变更请求。变更请求的优点在于,它们提供了决策记录,且其评估的流程还确保了变更的影响可在整个项目范围内得到认同和理解。系统测试,英文是System Testing。是将已经确认的软件、计算机硬件、外设、网络等其他元素结合在一起,进行信息系统的各种组装测试和确认测试,系统测试是针对整个产品系统进行的测试,目的是验证系统是否满足了需求规格的定义,找出与需求规格不符或与之矛盾的地方,从而提出更加完善的方案。系统测试发现问题之后要经过调试找出错误原因和位置,然后进行改正。是基于系统整体需求说明书的黑盒类测试,应覆盖系统所有联合的部件。对象不仅仅包括需测试的软件,还要包含软件所依赖的硬件、外设甚至包括某些数据、某些支持软件及其接口等。
