PHP 5 Reflection access privat methods

There were highly idiologic discussions about if you should test your privates or not with unit testing or not, in my opinion especially during Development with private methods performing for example calculations it could be useful to Unit Test these. At least during development you make sure that these functions already work, and finally it´s better to change accessibility than just to set accessibility lower to make testing possible. Before PHP 5.3.2 it was not possible to change the accessibility but with the new ReflectionMethod it is. But this feature needs to be used with care, it´s made for unit testing and maybe very special other cases wich are not in my mind yet. Using some magic reflection stuff always makes code very hard to read, maybe you think it´s fance but others might get confused a lot.
Using the ReflectionMethod introduced in PHP 5.3.2
ReflectionMethod::SetAccesible
ReflectionMethod Class

PHP Unit Developer Sebastian Bergmann wrote an article about Testing Your Privates
Sebastians Bergmanns Example:

<?php
class FooTest extends PHPUnit_Framework_TestCase
{
    public function testPrivateMethod()
    {
        $method = new ReflectionMethod(
          'Foo', 'doSomethingPrivate'
        );
        $method->setAccessible(TRUE);
        $this->assertEquals(
          'blah', $method->invoke(new Foo)
        );
    }
}
?>
