Why is my response not complete when running pytest

[miazocool]

Hello, when running pytest, my get request only display this information
Attributes and relationships fields are missing

{'data': [{'id': '3f70944c-c681-4ca7-bc19-7fb217613cbd', 'type': 'Project'},
{'id': '86a3de70-2398-49dc-b4ae-c87beb6f2fe8', 'type': 'Project'}],
'links': {'self': 'http://testserver/api/v1/groups/5/relationships/projects'}}
