Forum OpenACS Q&A: Re: Seeking Information On Care And Feeding Of acs-automated-testing

I am bit confused by the example provided by acs-automated-testing.  In the aa_example-000 case, the is a call to aa_sub to replace the aa_example_write_audit_entry body.  In the body there is reference to sequence_id variable. Is this the number of times the procedure is called?  How is this sequence_id variable used?  Thanks.
