ios - 如何测试快速嵌套函数？

Question

如何编写 swift 嵌套函数的测试？

因为这个函数在另一个函数里面，所以我不知道如何从外面调用它。

我正在使用嵌套函数，因为我不能在 init 中调用私有(private) self 函数

Answer 1

你不应该测试嵌套函数，就像你不应该测试私有(private)方法一样，来自Bad Testing Practices :

Private means private. Period. If you feel the need to test a private method, there is something conceptually wrong with that method. Usually it is doing too much to be a private method, which in turn violates the Single Responsibility Principle.
