### Question:
TwoDigitYearLocalDateConverter implements Converter<LocalDate, LocalDate> { @Override public LocalDate convertToPresentation(LocalDate value, ValueContext context) { return value; }  @CheckForNull @Override Result<LocalDate> convertToModel(@CheckForNull LocalDate value, ValueContext context); @Override LocalDate convertToPresentation(LocalDate value, ValueContext context);  }### Answer:
@Test public void testConvertToPresentation_FourDigitYear_NoConversion() { assertThat((converter.convertToPresentation(LocalDate.of(2011, 9, 5), context)), is(LocalDate.of(2011, 9, 5))); }
@Test public void testConvertToPresentation_NullValue() { assertNull(converter.convertToPresentation(null, context)); }
@Test public void testConvertToPresentation_ThreeDigitYear_NoConversion() { assertThat((converter.convertToPresentation(LocalDate.of(312, 5, 1), context)), is(LocalDate.of(312, 5, 1))); }
@Test public void testConvertToPresentation_TwoDigitYear_NoConversion() { assertThat((converter.convertToPresentation(LocalDate.of(10, 3, 21), context)), is(LocalDate.of(10, 3, 21))); }
