cassandra unit test

[Stone Fang <cn...@gmail.com>]

Call QueryProcessor.execute method to insert data into table in cassandra
unit test file.

  public static UntypedResultSet execute(String query, ConsistencyLevel cl,
Object... values)
    throws RequestExecutionException
    {
        return execute(query, cl, internalQueryState(), values);
    }

As it's consistency level is local_quorum.So I can't call CQLTest.execute
method.

But I got this exception when insert data with this method.
I understand this is an error related to token range.
in ReplicationParams.validate method it calls
             TokenMetadata tmd = StorageService.instance.getTokenMetadata();
.
and tokenMetadata.sortedTokens()  is empty.and there is the cause of
exception.

I want to know how to assign the token range in cassandra unit test to
solve this problem.
anyone have idea about this?

Stone ,thanks
