### Question:
CardHolder implements Cloneable, Serializable, Loggeable { public boolean hasTrack1() { return track1!=null; } CardHolder();  CardHolder(String track2);  CardHolder(String pan, String exp);  CardHolder(ISOMsg m); void parseTrack2(String s); void setTrack1(String track1); String getTrack1(); boolean hasTrack1(); String getNameOnCard(); String getTrack2(); boolean hasTrack2(); void setSecurityCode(String securityCode); String getSecurityCode(); boolean hasSecurityCode(); @SuppressWarnings("unused") String getTrailler(); @SuppressWarnings("unused") void setTrailler(String trailer); String getTrailer(); void setTrailer(String trailer); void setPAN(String pan); String getPAN(); String getBIN(); void setEXP(String exp); String getEXP(); boolean isExpired(); boolean isExpired(Date currentDate); boolean isValidCRC(); static boolean isValidCRC(String p); void dump(PrintStream p, String indent); String getServiceCode(); boolean seemsManualEntry(); @Override int hashCode(); @Override boolean equals(Object obj);  }### Answer:
@Test public void testHasTrack1() throws Throwable { CardHolder cardHolder = new CardHolder(); cardHolder.setTrack1("testCardHolderTrack1"); boolean result = cardHolder.hasTrack1(); assertTrue(result, "result"); }
@Test public void testHasTrack11() throws Throwable { boolean result = new CardHolder("testCardHolderPan", "4Cha").hasTrack1(); assertFalse(result, "result"); }
