Unit testing

Unit testing can be done by following the strawberry's testing docs reference.

This lib also provides a TestClient and an AsyncTestClient that makes it easier to run tests by mimicing a call to your API.

For example, suppose you have a me query which returns the currently logged in user or None in case it is not authenticated. You could test it like this:

from strawberry_django.test.client import TestClient


def test_me_unauthenticated(db):
    client = TestClient("/graphql")
    res = client.query("""
      query TestQuery {
        me {
          pk
          email
          firstName
          lastName
        }
      }
    """)
    assert res.errors is None
    assert res.data == {"me": None}


def test_me_authenticated(db):
    user = User.objects.create(...)
    client = TestClient("/graphql")

    with client.login(user):
        res = client.query("""
          query TestQuery {
            me {
              pk
              email
              firstName
              lastName
            }
          }
        """)

    assert res.errors is None
    assert res.data == {
        "me": {
            "pk": user.pk,
            "email": user.email,
            "firstName": user.first_name,
            "lastName": user.last_name,
        },
    }
