推荐答案

在黑盒测试中，您并不关心被测试事物的内部结构如何工作.您调用公开的 API 并检查结果；你不在乎被测试的东西做了什么给你结果.

In black box testing, you don't care how the internals of the thing being tested work. You invoke the exposed API and check the result; you don't care what the thing being tested did to give you the result.

在白盒测试中，您确实关心被测试事物的内部结构如何工作.因此，您不仅可以检查事物的输出，还可以检查被测试事物的内部变量是否正确.

In white box testing, you do care how the internals of the thing being tested work. So instead of just checking the output of your thing, you might check that internal variables to the thing being tested are correct.

单元测试是一种测试软件组件的方式.单元"是被测试的东西.您可以使用单元测试进行黑白盒测试；这个概念与白盒/黑盒测试是正交的.

Unit testing is a way of testing software components. The "Unit" is the thing being tested. You can do both black and white box testing with unit tests; the concept is orthogonal to white/black-box testing.
