软件测试 白盒测试 语句覆盖 判定覆盖

前置知识

白盒测试用例设计方法（语句覆盖、判定覆盖、条件覆盖、判定/条件覆盖、组合覆盖、路径覆盖、基本路径覆盖）

语句覆盖：每条语句至少执行一次。

判定覆盖：每个判定的所有可能结果至少出现一次。（又称“分支覆盖”）

条件覆盖：每个条件的所有可能结果至少执行一次。

判定/条件覆盖：一个判定中的每个条件的所有可能结果至少执行一次，并且每个判断本身的所有可能结果至少执行一次。

多重条件覆盖（组合覆盖）：每个判定中的所有可能的条件结果的组合，以及所有的入口点都至少执行一次。（注意“可能”二字，因为有些组合的情况难以生成。）(所有条件都有出现,但是只是出现,不像路径覆盖)

路径覆盖：每条路径至少执行一次。

任何一种覆盖方法都无法实现完全的测试。所以，在实际的测试用例设计过程中，根据需要将不同的覆盖方法组合起来使用，以实现最佳的测试用例设计 。
