cassandraunit throws Dataset not found error

I am using cassandra-unit 3.0.0.1 from here but it is throwing dataset not found error

@Rule
public CassandraCQLUnit cassProvider = new CassandraCQLUnit(new ClassPathCQLDataSet("simple.cql","keyspaceNameToCreate"));

is there any other plugins i need to use or is it a bug in cassandra-unit?
