如何在Django中使用pytest？

当我将pytest与Django一起使用时，不会创建test_ <db_name>。

最小可复制示例：

在Django专案中：

./manage.py startapp testing_pytest

在models.py中

class Snippet(models.Model):

    created = models.DateTimeField(auto_now_add=True)
    title = models.CharField(max_length=100, blank=True, default='')
    code = models.TextField()
    linenos = models.BooleanField(default=False)
    external_id = models.CharField(max_length=100, default='0')

    class Meta:
        ordering = ['created']

然后在Postgres中创建一个名为loc_db的数据库，

./manage.py makemigrations
./manage.py migrate 

在serializers.py中

class BulkUpdateOrCreateListSerializer(serializers.ListSerializer):
    def create(self, validated_data):
        result = [self.child.create(attrs) for attrs in validated_data]
        try:
            res = self.child.Meta.model.objects.bulk_create(result)
        except IntegrityError as e:
            raise ValidationError(e)
        return res

class SnippetSerializer(serializers.ModelSerializer):
    class Meta:
        model = Snippet
        fields = ['id','title', 'code', 'linenos']
        read_only_fields = ['id']
        list_serializer_class = BulkUpdateOrCreateListSerializer

    def create(self, validated_data):
        instance = Snippet(**validated_data)
        if isinstance(self._kwargs["data"], dict):
            instance.save()
        return instance

在views.py中

class SnippetGetView(generics.ListAPIView):
    serializer_class = SnippetSerializer
    queryset = Snippet.objects.all()

class SnippetUpdateView(generics.ListCreateAPIView):
    queryset = Snippet.objects.all()
    serializer_class = SnippetSerializer
    def get_serializer(self, *args, **kwargs):
        if isinstance(kwargs.get("data", {}), list):
            kwargs["many"] = True
        return super(SnippetUpdateView, self).get_serializer(*args, **kwargs)

在tests.py中

@pytest.fixture(scope='session',autouse=True)
def my_faker():
    return Faker()

@pytest.fixture(scope='session',autouse=True)
def factory():
    return APIRequestFactory()

@pytest.fixture(scope='session',autouse=True)
def snippets():
    snippets = []
    for i in range(TEST_SIZE):
        snippets.append({'title':'snippet'+str(i),'code':'print(True)','linenos':False,'external_id':'1'})
    return snippets

@pytest.mark.django_db
def test_update_snippet(factory,snippets):
    request = factory.post('/add-snippets/',snippets)
    view = SnippetUpdateView.as_view()
    response = view(request)
    response.render()
    assert status.is_success(response.status_code)

并在<project_name> /settings.py中

DATABASES = {
    'default': {
        'ENGINE': 'django.db.backends.postgresql_psycopg2',
        'NAME': 'loc_db',
        'USER': '<some name>',
        'PASSWORD': '<some pass>',
        'HOST': 'localhost',
        'PORT': '5432',
    }
}

并在pytest.ini中

[pytest]
DJANGO_SETTINGS_MODULE = <project_dir>.settings
python_files = tests.py test_*.py *_tests.py

我希望在执行这些测试时运行pytest可以创建test_loc_db，然后保存该代码片段数组以进行批量创建。但是，没有创建test_db。相反，它只是通过了该测试。但我不确定为什么。这些摘要保存在哪里？
