Tests repeats the code with Mockito

My tests just repeats the code. For method

public void start(Context context) {
    context.setA(CONST_A);
    context.setB(CONST_B);
    ...
}

I wrote test using Mockito

@Test
public void testStart() throws Exception {
    Context mockContext = mock(Context.class);

    action.start(mockContext);

    verify(mockAction).setA(Action.CONST_A);
    verify(mockAction).setB(Action.CONST_B);
    ...
}

Or for

public void act() {
   state.act();
}

test

@Test
public void testAct() throws Exception {
    State mockState = mock(State.class);
    context.setState(mockState);

    context.act();

    verify(mockState).act();
}

Are such tests useful? Such methods need to be tested and how to test them?
