cassandra - CassandraCQLUnit 给出空会话

Question

我的测试类中有以下代码。当我得到 Session 它总是空的

@Rule
    public CassandraCQLUnit cassandraCQLUnit = new CassandraCQLUnit(new ClassPathCQLDataSet("middle.cql","metadata"));

    private Session session = cassandraCQLUnit.getSession();

    @Test
    public void SetUp(){
        logger.info(session);
    }
