class ProtectedPrivates in Examples for Developers 3.x

Same name and namespace in other branches
  1. 8 phpunit_example/src/ProtectedPrivates.php \Drupal\phpunit_example\ProtectedPrivates

A class with features to show how to do unit testing.

This class has private and protected methods to demonstrate how to test with reflection and mocking.

protectedAdd() and privateAdd() are shim methods to AddClass::add(). We do this so we're concentrating on the testing instead of the code being tested.
