VisibleForTesting

@Retention(value = CLASS) annotation VisibleForTesting


Denotes that the class, method or field has its visibility relaxed, so that it is more widely visible than otherwise necessary to make code testable.

You can optionally specify what the visibility should have been if not for testing; this allows tools to catch unintended access from within production code.

Example:

 @VisibleForTesting(otherwise = VisibleForTesting.PROTECTED)
 public String printDiagnostics() { ... }
If not specified, the intended visibility is assumed to be private.
