我想要运行下面出现错误的测试用例.

运行commond:python manage.py test

如果您想尝试删除测试数据库'test_project_management_db',请输入'yes',或者取消'no'取消:是为别名'default'销毁旧测试数据库...

我在运行这些测试用例时为我的项目编写了一些测试用例,每次在给出消息然后销毁数据库之后创建别名'default'的测试数据库.我只关注消息,所以如何避免创建测试数据库,因为它需要很多时间.

username$ ./manage.py test
...............
Some message, I Want only this message 
...............
Creating test database for alias 'default'...
----------------------------------------------------------------------
Ran 0 tests in 0.000s

OK
Destroying test database for alias 'default'...

我正在尝试使用来自 drf-extensions 的批量更新。为了使其工作，有一个安全措施需要标题“X-BULK-OPERATION”：'true'。我可以使用 curl 或我的 angular 应用程序使应用程序正常工作，但在我的测试中，我试图rest_framework.test.APIClient用来发送 partial_update 请求，但每次我收到 400 响应时，在调试请求时，我都会收到

ipdb> response.data
{'detail': "Header 'X-BULK-OPERATION' should be provided for bulk operation."}

这是我尝试在测试中使用的请求

    response = self.client.patch(
        '/api/v1/db_items/?active=True',
        json.dumps(data),
        content_type='application/json',
        **{X-BULK-OPERATION: 'true'}
    )

有没有办法在 APIClient 请求上设置标头？

我什至尝试更改标题名称并将其设置在凭据中

self.client.credentials(HTTP_BULK_OPERATION='true')

但我每次都会遇到同样的错误

有没有办法在django测试中检查两个对象列表是否相等.

让我说我有一些模型:

class Tag(models.Model):
    slug = models.SlugField(max_length=50, unique=True)
    def __unicode__(self):
        return self.slug

我运行这个简单的测试:

def test_equal_list_fail(self):
    tag_list = []
    for tag in ['a', 'b', 'c']:
        tag_list.append(Tag.objects.create(slug=tag))

    tags = Tag.objects.all()

    self.assertEqual(tag_list, tags)

这失败了:

======================================================================
FAIL: test_equal_list_fail (userAccount.tests.ProfileTests)
----------------------------------------------------------------------
Traceback (most recent call last):
  File "path/to/tests.py", line 155, in test_equal_list_fail
    self.assertEqual(tag_list, tags)
AssertionError: [<Tag: a>, <Tag: b>, <Tag: c>] != [<Tag: a>, <Tag: b>, <Tag: c>]

----------------------------------------------------------------------

这将工作:

def test_equal_list_passes(self):
    tag_list = []
    for tag in ['a', 'b', 'c']:
        tag_list.append(Tag.objects.create(slug=tag))

    tags = Tag.objects.all() …

我在django中有以下test.py文件.你能解释一下这段代码吗？

from contacts.models import Contact
...
class ContactTests(TestCase):
    """Contact model tests."""

    def test_str(self):

        contact = Contact(first_name='John', last_name='Smith')

        self.assertEquals(
            str(contact),
            'John Smith',
        )

我想用一个临时数据库启动django shell(就像做django测试时所做的那样)

有没有像这样的命令:

python manage.py testshell

在哪里我可以创建一堆虚假模型而不污染我的数据库？

如何定义依赖于其他字段使用的字段factory-boy？

例如,我想定义一个email取决于first name和last name的User.

我尝试使用post_generation装饰器.但是,我的系统需要在创建实例之前定义电子邮件.

我是单元测试的新手,所以我不知道我做错了什么.我在Django1.8中使用python2.7

我跑的时候

python manage.py test myapp --keepdb

我明白了

我想编写一个抽象模型mixin,我可以使用它来创建OneToOne - 与用户模型的关系.这是我的代码:

from django.conf import settings
from django.db import models


class Userable(models.Model):
    user = models.OneToOneField(
        settings.AUTH_USER_MODEL,
        on_delete=models.CASCADE
    )

    class Meta:
        abstract = True

我为这个模型编写了以下测试:

class TestUserable(TestCase):

    mixin = Userable

    def setUp(self):
        user = User.objects.create_user(
            email="testuser@test.com",
            name="Test User",
            password="test1234test"
        )
        self.user = user
        self.model = ModelBase(
            '__TestModel__' + self.mixin.__name__, (self.mixin,),
            {'__module__': self.mixin.__module__}
        )

        with connection.schema_editor() as schema_editor:
            schema_editor.create_model(self.model)

    def test_user(self):
        self.model.objects.create(user=self.user)
        self.assertEqual(self.model.objects.count(), 1)

    def tearDown(self):
        with connection.schema_editor() as schema_editor:
            schema_editor.delete_model(self.model)

我的问题是,在它的tearDown()方法中的这个测试抛出了以下错误:

django.db.utils.OperationalError: cannot DROP TABLE "core___testmodel__userable" because it …

如何在TestCase方法中使用 pytest 固定装置？类似问题的几个答案似乎暗示我的例子应该有效：

import pytest

from django.test import TestCase
from myapp.models import Category
  
pytestmark = pytest.mark.django_db

@pytest.fixture
def category():
    return Category.objects.create()
  
class MyappTests(TestCase):
    def test1(self, category):
        assert isinstance(category, Category)

但这总是会导致错误：

TypeError: test1() missing 1 required positional argument: 'category'

我意识到我可以将这个简单的例子转换成一个函数，它会起作用。我更喜欢使用 django，TestCase因为它支持导入传统的“django fixture”文件，这是我的几个测试所需要的。将我的测试转换为函数需要重新实现这个逻辑，因为没有记录的方式使用 pytest（或 pytest-django）导入“django 固定装置”。
