在这个过程的这一点上,用例为识别有效测试,清除多余路径,以及在不用猜想的情况下设计黑盒测试提供了一个方法作为覆盖范围。
At this point in the process, use case implementation provides a means to identify invalid tests, remove redundant paths, and plan black box testing with no guesswork as to coverage.
由于用例可以通过黑盒访问这个系统,所以它们成为单元测试人员的关键性驱动。
Since use cases take a black box approach to the system, they cannot be critical drivers for the unit testers.
将系统视为一个黑盒,确定与系统(系统参与者)交互的环境元素和实际的相互作用及结果(系统用例及产生的服务)。
Treating the system as a black box, identify environmental elements that interact with the system (the system actors) and the actual interactions and results (system use cases and resulting services).
