How to convert Avro GenericRecord to AvroKey?

Hello,  I am using Avro files for Hadoop MaprReduce.  My Mapper function has following definition.
Mapper <AvroKey<GenericRecord>,NullWritable, AvroKey<GenericRecord>,AvroValue<GenericRecord>>
For writing unit tests for above Mapper function I need to pass AvroKey<GenericRecord>. How do I convert GenericRecord to AvroKey<GenericRecord> ? 
Is there any example available ?
Thanks,Ravi

Ravi,

Moving this to the Avro user lists (user@avro.apache.org).

You can simply do a "AvroKey<GenericRecord> key = new
AvroKey<GenericRecord>(datum)".
