Mockito: Verify Mock (with “RETURNS_DEEP_STUBS”) Returns More Calls Than Expected

Question

Looking at the code below, I only expect the call to getSand() to happen once, but the test is failing with four calls to it. Where are these calls happening? I wan

From the documentation of Answers.RETURNS_DEEP_STUBS:

Please see the {@link org.mockito.Mockito#RETURNS_DEEP_STUBS} documentation for more details.

From Mockito.RETURNS_DEEP_STUBS:

Verification only works with the last mock in the chain. You can use verification modes. 
[...]
when(person.getAddress(anyString()).getStreet().getName()).thenReturn("deep");
[...]
inOrder.verify(person.getAddress("the docks").getStreet(), times(1)).getName();

So, I think, in order to get your verifies to work, you have to rewrite your Mocks to something like this:

@Mock
SandBox mockSandBox;

@Mock
Sand mockSand;

@Test
public void should()
{
    when( mockSand.doA() ).thenReturn( 1 );
    when( mockSand.doB() ).thenReturn( 1 );
    when( mockSand.doC() ).thenReturn( 1 );

    when( mockSandBox.getSand() ).thenReturn( mockSand );

    DeepSand deepSand = new DeepSand( mockSandBox );
    deepSand.getTipple();

    verify( mockSandBox, times( 1 ) ).getSand();
}

Or only verify the invocations of doA, doB and doC and not verify the invocation of getSand(). - Which depends on what exactly you want to test for here.
