        claim_predicate='<http://xmlns.com/foaf/0.1/knows>'

    she_knows = [await claim.get_object() for claim in claims]

    print(she_knows)
    ['<www.example.com/my_other_friend>', ]

To test

Have a test instance of a RDF store. Be aware that testing requires modification and deletion of the RDF store. Set the address of the RDF store in the testing.cfg.

Run pytest tests/
