Django Test：__init __（）获得了意外的关键字参数'failfast'

Question

我的Django应用出现问题，这周我添加了一些模型和测试，但是当我要使用“ python manage.py test” 进行测试时，出现此错误：

TypeError: __init__() got an unexpected keyword argument 'failfast'

我试图查看我的模型/序列化器/测试中是否存在一些错误（语法错误），甚至试图回到古老的工作提交中，但是在测试时并不能解决我的问题... 另外，当我使用“ python manage.py runserver” 时，服务器可以正常工作。

Creating test database for alias 'default'...

TypeError: __init__() got an unexpected keyword argument 'failfast'

我不在命令行中使用failfast参数，因此此错误对我没有任何意义。 我使用Django 2.2.2！

以下是我的测试内容的摘要：

from django.utils import timezone
from django.test import TransactionTestCase
from apps.myheart.api.api_acquisitions_markers import acquisitions_markers_get
from apps.myheart.models import Implants, Markers, AcquisitionsMarkers, Acquisitions
from datetime import timedelta, datetime
from .test_authentication import authenticate

class ImplantsAPIViewTestCase(TransactionTestCase):


    def setUp(self):
            self.implant1 = Implants.objects.create(
                num=1, implantation_date=datetime(2012, 11, 20, 20, 8, 7, 127325, tzinfo=pytz.UTC), implantation_hopital="hopital1"
            )
            self.implant2 = Implants.objects.create(
                num=2, implantation_date=datetime(2014, 11, 18, 20, 8, 7, 127325, tzinfo=pytz.UTC), implantation_hopital="hopital2"
            )
            self.implant3 = Implants.objects.create(
                num=34, implantation_date=datetime(2016, 10, 18, 20, 8, 7, 127325, tzinfo=pytz.UTC), implantation_hopital="hopital1"
            )
            self.token = authenticate()
            self.nb_imp = len(Implants.objects.all())


    def test_implants_get(self):
        info("Test /api/implants/\n")
        response = self.client.get("/api/implants/", HTTP_AUTHORIZATION=self.token)
        info(response.data)
        # We need to check that we have all the files presents in DB
        self.assertEqual(len(response.data), self.nb_imp)
        info("\n")

Answer 1

我刚刚找到了我的错误，似乎是XMLRunner和unittest-xml-reporting向我报告了此错误。由于我使用它们已有一段时间了，所以效果很好，我不知道为什么现在不工作了，但是删除它们可以解决问题。

Answer 2

我在django项目中遇到过与python 2相同的问题，但是当我切换到python 3时神秘地停止了工作。

对我来说，解决方案是从xmlrunner包切换到unittest-xml-reporting

即试试这个：-

biClrUsed

不再支持xmlrunner软件包，替换为unittest-xml-reporting。

Answer 3

Django测试： init （）获得了意外的关键字参数'failfast' 我花了点时间在这个站点的帮助下弄清楚了这一点。为pipenv添加答案。 pipenv卸载xmlrunner pipenv安装unittest-xml-报告
