title: JUnit for getters and setters
body: <p>As it was highly recommended in one of the books I'm reading I've started to write tests for each of the class I'm creating. I'm not really sure what is a good practice to cover setters and getters or not. If yes I'm not sure how because to verify the setter method you need to call the getter for this variable and vice versa. So you will never know where the actual problem is. 
  Where I went is just similar tests for setters and getters.</p>
