从最终类（实用程序类）模拟私有静态方法

Question

I am using Mockito and PowerMock to do some testing to my Java app. I was wondering how I can mock a private static method from a final class. I want to simulate an Exception when accessing one method but the only way I have found to do it is if the class can be instantiated and using the spy() method from PowerMock.

Could anyone help/guide me a little?

Answer 1

Here is an example using PowerMock to mock public static methods .

In case of a private method there must be some public static method somewhere to mock that calls this private method, as you can not call it directly. If you are only interested in an exception, you might throw the exception earlier (maybe - many assumptions)
