Instruments implements Iterable<Instrument> { public String getPricePlaceholder() { return pricePlaceholder; } private  Instruments(Instrument[] values, int priceIntegerDigits, int maxPriceFractionDigits,
            int sizeIntegerDigits, int maxSizeFractionDigits); Instrument get(String instrument); Instrument get(long instrument); Iterator<Instrument> iterator(); int getMaxPriceFractionDigits(); int getMaxSizeFractionDigits(); int getPriceWidth(); int getSizeWidth(); String getPricePlaceholder(); String getSizePlaceholder(); static Instruments fromConfig(Config config, String path);  }### Answer:
@Test public void pricePlaceholder() { assertEquals(" - ", FRACTIONS.getPricePlaceholder()); }
