### Question:
DelegatingModelBasedArgumentConverter extends ModelBasedArgumentConverter { @Override public boolean canConvert(Object argument) { for (ArgumentConverter argumentConverter : argumentConverters) { if (argumentConverter.canConvert(argument)) { return true; } } return false; } DelegatingModelBasedArgumentConverter(Collection<ArgumentConverter> argumentConverters); @Override void initialize(ModelConverter modelConverter); @Override boolean canConvert(Object argument); @Override Object convert(Object argument);  }### Answer:
@Test void canConvertReturnsTrueIfOneConverterCanConvert() { final ModelBasedArgumentConverter first = Mockito.mock(ModelBasedArgumentConverter.class); final ModelBasedArgumentConverter second = Mockito.mock(ModelBasedArgumentConverter.class); final DelegatingModelBasedArgumentConverter delegatingConverter = new DelegatingModelBasedArgumentConverter(Arrays.asList(first, second)); when(first.canConvert(any())).thenReturn(true); when(second.canConvert(any())).thenReturn(false); assertTrue(delegatingConverter.canConvert("test")); when(first.canConvert(any())).thenReturn(false); when(second.canConvert(any())).thenReturn(true); assertTrue(delegatingConverter.canConvert("test")); when(first.canConvert(any())).thenReturn(false); when(second.canConvert(any())).thenReturn(false); assertFalse(delegatingConverter.canConvert("test")); when(first.canConvert(any())).thenReturn(true); when(second.canConvert(any())).thenReturn(true); assertTrue(delegatingConverter.canConvert("test")); }
