Java tool for testing private methods?

Question

There are different opinions on the meaningfulness of testing of private methods, e.g., here and here. I personally think it makes sense, the question is how to do it properly.

Answer 1

It seems like a lot of trouble to do this implementation. It may not be worth it. Rather just make the method package default.

However, if you are determined to call private method, you can use setAccessible in yourDecapsulated_something class to allow call via reflection. So it's fairly simple.
