+ * Circumvent access restrictions on object internals

+ * This can be helpful for writing tests that can probe object internals,
+ * without having to modify the class under test to accomodate.
+ *
+ * Wrap an object with private methods as follows:
+ * $title = TestingAccessWrapper::newFromObject( Title::newFromDBkey( $key ) );
+ *
+ * You can access private and protected instance methods and variables:
+ * $formatter = $title->getTitleFormatter();
+ *
+ * TODO:
+ * - Provide access to static methods and properties.
+ * - Organize other helper classes in tests/testHelpers.inc into a directory.
