title: JUnit: using constructor instead of @Before
body: <p>I'm using JUnit 4. I can't see the difference between initializing in the constructor or using a dedicated init function annotated by <code>@Before</code>. Does this mean that I don't have to worry about it?</p>
  
  <p>Is there any case when <code>@Before</code> gives more than just initializing in the constructor?</p>
