How would I write a test to cover lines of code that fall through the cracks, sample provided

I am trying to acheive 100% code coverage, but I cannot determine how to cover lines like #57 below. It is simply an ending }. I have these lines throughout all of my code, as well as lines like, } else {, but they are not covered, nor marked as dead code.

How would I write a test to cover these lines?

From a first glimpse of the code, I'd say that line 40 (if ($form->isValid($this->getRequest()->getPost())) {) always evaluates to true in your tests and therefore the function addAction is always left with the return; statement in line 53.
