I must covered whit Junit4 and Mockito/PowerMockito the While Block and the catch block.
The Exception StateException is launched by the getHrest method

```
public class Fstate{
 ….
private Date selectedDate;
private Date dateYes;
private Collection<State> sStateList;
private boolean statePlus;
private String stateVisibility;

@EJB
private Muller mull;
….
public void methodState(){
    final Calendar calendar=new GregorianCalendar();
    this.dateYes=calendar.getTime();
    this.selectedDate = this.dateYes;
    Collection<State> allState=null;
    try{
        allState=this.mull.getHrest(this.p, this.b, this.ba, this.so);
        Iterator<State> iter=allState.iterator();
        while(iter.hasNext()){
            State s=iter.next();
            String s_string=s.getSfielString(); 
            this.sStateList.add(s_string);
        }
     } catch (StateException stateException){
        WebLogger.fatal(stateException.getMessage(), LOGGER_OUT);
    }
    this.statePlus=loadStatePlus(this.dateYes);
    this.stateVisibility=STATE_PLUS;
}
}

```

Below, in the first method I want to cover the while execution while in the second method I want to cover the catch.
However, this does not generate the expected result, while block and catch not covered!

```
@Test
public void state_Test(){
    try {

        Fstate spyFstate = Mockito.spy(Fstate.class);

        State mockState=Mockito.mock(Muller.class);     

        Mockito.when(mockState.getHrest(anyString(), anyString(), anyString(), anyString())).thenReturn(createCollectionOfStates());
        Whitebox.setInternalState(spyFstate, "mull",mockState);

        spyFstate.methodState();
        Mockito.verify(spyFstate, Mockito.times(1)).methodState();

    } catch (StateException e) {
        System.out.println("StateException in state_Test method!");
    }
}

@Test
public void stateException_Test(){
    try {
            Fstate spyFstate = Mockito.spy(Fstate.class);

            State mockState=Mockito.mock(Muller.class); 

            Mockito.when(mockState.getHrest(anyString(), anyString(), anyString(), anyString())).thenThrow(new StateException("StateException Exception"));

            Whitebox.setInternalState(spyFstate, "mull",mockState);
            spyFstate.methodState();

            Mockito.verify(spyFstate, Mockito.times(1)).methodState();

    } catch (DealAnagException e) {
            e.printStackTrace();
    }   
}

```
