from [PHPUnit documentation](http://www.phpunit.de/manual/current/en/fixtures.html#fixtures.more-setup-than-teardown) :

>setUp() and tearDown() are nicely symmetrical in theory but not in practice. In practice, you only need to implement tearDown() if you have allocated external resources like files or sockets in setUp(). If your setUp() just creates plain PHP objects, you can generally ignore tearDown(). However, if you create many objects in your setUp(), you might want to unset() the variables pointing to those objects in your tearDown() so they can be garbage collected. The garbage collection of test case objects is not predictable.

All these tearDown methods are not needed and should be removed.
