Starting an embedded Cassandra instance for Unit tests

I need to start a Embedded cassandra instance to perform some operations on a Cassandra keyspace via Unit tests. Programming Language is Java. What are the options to start an embedded cassandra?

I used the mojo maven plugin, however after starting the instance using following command, I do not see the cassandra instance started at default port 9042 on localhost. Plugin:http://ift.tt/2qxeWtV Command to start: mvn cassandra:run -Dcassandra.nativeTransportPort=9042

Is there something missing in terms of usage or do I need to use something different?

Thanks Jyothi
