IntelliJ：如果我调用以@VisibleForTesting注释的方法，则会收到警告

Question

I have the following use case:

I want to Unit-test a private method (I really want to). Now, there are different approaches, but I want to choose the approach "make the method package private".

In Guava, there's an annotation called @VisibleForTesting . What I want to do is: Whenever this method is called from another class (in the same package, of course), regardless of it's a subclass of this class or not, display a warning like "Hey dude, the method you want to call is marked with @VisibleForTesting, are you sure you want to call it?".

I played a bit with custom inspections , but with no luck so far. Does anyone have an idea?

Answer 1

There is no need for a custom inspection, the necessary inspection is built in. Go to Preferences | Editor | Inspections Preferences | Editor | Inspections Preferences | Editor | Inspections and enable the inspection Java | General | Test-only class or method call in production code Java | General | Test-only class or method call in production code Java | General | Test-only class or method call in production code . Now you will get a warning if you try to call members with the @VisibleForTesting annotation from production code, but not from test code.
