/**
* Allows shorthand wrapping of field instances in an spy object.
*
*
* Example:
*
*
* public class Test{
* @Spy Foo spyOnFoo = new Foo();
* @Before
* public void init(){
* MockitoAnnotations.init(this);
* }
* ...
* }
*
*
* Same as doing:
*
*
* Foo spyOnFoo = Mockito.spy(new Foo());
*
*
* Warning if you call MockitoAnnotations.init(this) in a
* super class constructor then this will not work. It is because fields
* in subclass are only instantiated after super class constructor has returned.
* It's better to use @Before.
