### Question:
SummarizerUtils { public static String date(LocalDate date) { return date.format(DATE_FORMAT); } private  SummarizerUtils(); static String date(LocalDate date); static String dateRange(LocalDate start, LocalDate end); static String datePeriod(LocalDate start, LocalDate end); static String amount(CurrencyAmount currencyAmount); static String amount(Currency currency, double value); static String value(double value); static String percent(double value); static String payReceive(PayReceive payReceive); static String fx(CurrencyAmount base, CurrencyAmount counter); static PortfolioItemSummary summary(Position position, ProductType type, String description, Currency... currencies); static PortfolioItemSummary summary(Trade trade, ProductType type, String description, Currency... currencies);  }### Answer:
@Test public void test_date() { assertThat(SummarizerUtils.date(LocalDate.of(2017, 10, 12))).isEqualTo("12Oct17"); assertThat(SummarizerUtils.date(LocalDate.of(2017, 4, 3))).isEqualTo("3Apr17"); }
