### Question:
ChainContainer implements Cloneable { public MeetingRound getCurrentRound() { return roundManager.getCurrentRound(); } ChainContainer(Chain chain); boolean addBlock(Block block); Result verifyBlock(Block block); Result verifyBlock(Block block, boolean isDownload, boolean isNeedCheckCoinBaseTx); boolean verifyCoinBaseTx(Block block, MeetingRound currentRound, MeetingMember member); boolean verifyPunishTx(Block block, MeetingRound currentRound, MeetingMember member); Result verifyAndAddBlock(Block block, boolean isDownload, boolean isNeedCheckCoinBaseTx); boolean rollback(Block block); ChainContainer getBeforeTheForkChain(ChainContainer chainContainer); ChainContainer getAfterTheForkChain(ChainContainer chainContainer); MeetingRound getCurrentRound(); MeetingRound getOrResetCurrentRound(); MeetingRound getOrResetCurrentRound(boolean isRealTime); MeetingRound initRound(); void clearRound(int count); Block getBestBlock(); Chain getChain(); void setChain(Chain chain); @Override boolean equals(Object obj); RoundManager getRoundManager();  }### Answer:
@Test public void testInit() { assertNotNull(chain); assertNotNull(chainContainer); assertNotNull(chainContainer.getCurrentRound()); assertEquals(chainContainer.getCurrentRound().getMemberCount(), 1); }
