问题
In Java, helper methods are often marked protected instead of private, so that unit tests within the same package can test the helper methods. (Specifically, I am using JUnit.)
This does not seem to work in Kotlin. What access modifier is recommended instead?
回答1:
internal (or no modifier) works well here
