Cassandra datastax 3.11.5 compatability

I have used datastax driver 3.11.5 version to connect to cassadra instance in version 4.x .Is this compatable ? Also when I am using EmbeddedCassandraServiceHelper from cassandra-unit version 4.3.1.0 for junit testing. Getting error :

Test.java:[38,58] error: incompatible types: CqlSession cannot be converted to Session Test.java:[38,66] error: incompatible types: CqlSession cannot be converted to Session

       @Before
    public void setUp() {
        session = EmbeddedCassandraServerHelper.getSession();
        dao = new CompressingDataDao<>(session, XY.class);
    }
 @Test
    public void getOne() throws Exception {
        String id = "abc";
        XY list = createAndSaveEnitty(id);

        XY listFromDB = dao.getOne(id);

        Assert.assertEquals(list, listFromDB);
    }


If driver 3.11.5 is compatable with cassandra version 4, How to do Unit testing as above method is giving error.

Cassandra Java Driver 3.11 is compatible with Cassandra 4. But cassandra-unit is using Cassandra Java Driver 4.x. So it seems to me that your dependency is messed up.

Cassandra Java Driver 4.x used modern designs and introduced a lot of breaking changes. Cassandra Java Driver 3.x is not maintained anymore. I would recommend you to upgrade your driver to 4.x.
