Testing Django GraphQL API with database

Question

I am using

from graphene_django.utils.testing import GraphQLTestCase

to implement my tests. However, the result from

class PeopleTests(GraphQLTestCase):
  GRAPHQL_SCHEMA = schema

  def test_all_person_query_admin_token(self):

    response = self.query(
        '''
       query getPersons{
            persons{
            firstName,
            lastName
            }
        }
        ''',
        op_name='persons',
        headers={'HTTP_AUTHORIZATION': f'JWT eyJ0eXAiOiJKV1QiLCJhbGciOiJIUzI1NiJ9.eyJ1c2VybmFtZSI6ImFkbWluIiwiZXhwIjoxNTY2MTk4Mzg5LCJvcmlnSWF0IjoxNTY2MTk4MDg5fQ.P4u7PNKPLFsc4dvhBLw-EfuN8jg2d-lqdZjWruEDlpc'}
    )

is always returns an empty list of Person. I read in Django Test Database looks empty while test is runnin that this is a result from GraphQLTestCase inheriting from TestCase. This post is very old (2012) but I can not seem to find any documentation on how to use a propper test database.

Sorry if I have missed something, and the answer was obvious.

Thanks

Please make sure that you are creating persons before fetching data with GraphQL. Maybe you need to add some fixtures or add a setUp method to add some entries. Here is how I tested Graphene-Django API with Pytest.

@pytest.mark.django_db
class TestBlogSchema(TestCase):

    def setUp(self):
       self.client = Client(schema)
       self.blog = mixer.blend(Blog)

    def test_single_blog_query(self):
       response = self.client.execute(single_blog_query, variables={"id": self.blog.id})
       response_blog = response.get("data").get("blog")

       assert response_blog["id"] == str(self.blog.id)
