While it is variously referred to as branch, path, or variability identification, in all cases the test designer identifies the various ways the user or external system can execute the use case.

有时它会被引用作为不同的分支、路径，或者变异性识别，在测试设计者识别各种方法的所有用例中，用户或者外部的系统都可以执行这个用例。

Coverage analysis also helps find out if there are any redundant test cases: tests that exercise the same path in the code over and over again, causing unnecessary delays.

覆盖率分析也可以帮您找到测试用例是否有冗余：测试在代码的同一路径下反复运行，导致了不必要的时间延迟。

Patients (51 cases) of test group were given intensification therapy according to the standard clinical path. While patients (50 cases) of control group were treated as routinely.

实验组(51例)按标准的临床路径进行强化治疗，对照组(50例)按常规方法进行治疗。

First one, when I write a piece of code, especially code that has branches in it, when I design test cases for that piece of code, I should try and have a specific test case for each possible path through the code.

第一点，当我们写代码的时候，尤其是一些含有分支语句的代码的时候，当我为这些代码,设计测试用例的时候，我应该为每一个可能的程序路径,都设计一个特别的用例。
