如何在Django中编写图形化GraphQL测试

Question

请任何人帮助测试石墨烯和图形ql与django

我尝试使用内置的django测试，但它没有看到我的文件 我使用了pytest，但它在导入模式时抱怨ModuleNotFoundError 我想有人给我看一门关于高级python的课程

class Query(ObjectType):
    calculate_price = Float(margin=Float(), exchangeRate=String(
    ), saleType=Argument(SaleType, required=True))

    def resolve_calculate_price(self, info, **kwargs):
        margin = kwargs.get('margin')
        exchangeRate = kwargs.get('exchangeRate')
        saleType = kwargs.get('saleType')

        request_from_coindesk = requests.get(
            url='https://api.coindesk.com/v1/bpi/currentprice.json')
        json_result_from_coindesk = json.dumps(request_from_coindesk.text)
        coindesk_result = json.loads(json_result_from_coindesk)
        result = json.loads(coindesk_result)

        rate_to_calculate = result["bpi"]["USD"]["rate_float"]

        if saleType == SaleType.sell:
            calculated_value = (margin/100) * rate_to_calculate
            new_rate = (rate_to_calculate - calculated_value) * 360
            print(18, new_rate)
            return new_rate
        elif saleType == SaleType.buy:
            calculated_value = (margin/100) * rate_to_calculate
            new_rate = (rate_to_calculate - calculated_value) * 360
            print(19, new_rate)
            return new_rate
        else:
            raise GraphQLError('please saleType can either be buy or sell')

我想测试所有可能的病例。 我想了解模块导入问题 我希望有人能参考一门高级python课程

下面是一个如何使用django和graphene测试graphql的示例，graphene-django：

from buy_coins.schema import Query
from django.test.testcases import TestCase
import graphene

class AnExampleTest(TestCase):

    def setUp(self):
        super().setUp()
        self.query = """
            query {
              reporter {
                id
              }
            }
        """

    def test_an_example(self):
        schema = graphene.Schema(query=Query)
        result = schema.execute(query)
        self.assertIsNone(result.errors)
        self.assertDictEqual({"reporter": {"id": "1"}}, result.data)
