### Question:
WxMpCardServiceImpl implements WxMpCardService { @Override public String getCardApiTicket() throws WxErrorException { return getCardApiTicket(false); } WxMpCardServiceImpl(WxMpService wxMpService); @Override WxMpService getWxMpService(); @Override String getCardApiTicket(); @Override String getCardApiTicket(boolean forceRefresh); @Override WxCardApiSignature createCardApiSignature(String... optionalSignParam); @Override String decryptCardCode(String encryptCode); @Override WxMpCardResult queryCardCode(String cardId, String code, boolean checkConsume); @Override String consumeCardCode(String code); @Override String consumeCardCode(String code, String cardId); @Override void markCardCode(String code, String cardId, String openId, boolean isMark); @Override String getCardDetail(String cardId); @Override String addTestWhiteList(String openid); @Override WxMpCardCreateResult createCard(WxMpCardCreateMessage cardCreateMessage); @Override WxMpCardQrcodeCreateResult createQrcodeCard(String cardId, String outerStr); @Override WxMpCardQrcodeCreateResult createQrcodeCard(String cardId, String outerStr, int expiresIn); @Override WxMpCardLandingPageCreateResult createLandingPage(WxMpCardLandingPageCreateRequest request); @Override String unavailableCardCode(String cardId, String code, String reason); @Override WxMpCardDeleteResult deleteCard(String cardId);  }### Answer:
@Test public void testGetCardApiTicket() throws Exception { String cardApiTicket = this.wxService.getCardService().getCardApiTicket(); assertNotNull(cardApiTicket); System.out.println(cardApiTicket); }
@Test public void testGetCardApiTicketWithParam() throws Exception { String cardApiTicket = this.wxService.getCardService().getCardApiTicket(true); assertNotNull(cardApiTicket); System.out.println(cardApiTicket); }
