我正在为 post 方法编写单元测试方法，但由于某种原因，它不断修改实际数据库而不是模拟数据库。 这是我的测试方法：
def test_post_contest(self):
mock_collection = self.mock_db.collection.return_value
mock_document = mock_collection.document.return_value
mock_document.set.return_value = None
response = self.client.post(
reverse('contest-list'),
data={
'ONI2024F2': {
'name': 'ONI2024F2',
'problems': ['problem1', 'problem2'],
'administratorId': '0987654321'
}
},
format='json'
)
self.assertEqual(response.status_code, 201)
self.assertEqual(response.json(), {'id': 'ONI2024F2'})
这是setUp方法：
def setUp(self):
self.client = APIClient()
self.mock_db = patch('firebase_config.db').start()
self.addCleanup(patch.stopall)
这是 firebase_config.py 文件
import os
import firebase_admin
from firebase_admin import credentials, firestore
#Path to Firebase credentials
cred_path = os.path.join(os.path.dirname(__file__), 'credentials','firebase_credentials.json')
#Initialize Firebase
cred = credentials.Certificate(cred_path)
firebase_admin.initialize_app(cred)
#Firestore client
db = firestore.client()
这是整个测试文件：
from django.test import TestCase
from django.urls import reverse
from unittest.mock import patch, MagicMock
from rest_framework.test import APIClient
class ContestViewTest(TestCase):
def setUp(self):
self.client = APIClient()

self.addCleanup(patch.stopall)
@patch('OIECApp.views.ContestView.referenceToJson')
def test_get_contest_list(self, mock_referenceToJson):
mock_referenceToJson.return_value = {'name': 'ONI2024F1'}
mock_collection = self.mock_db.collection.return_value
mock_doc = MagicMock()
mock_doc.id = 'ONI2024F1'
mock_collection.stream.return_value = [mock_doc]
response = self.client.get(reverse('contest-list'))
self.assertEqual(response.status_code, 200)
self.assertEqual(response.json(), {'IOI2023': {'name': 'ONI2024F1'}, 'ONI2024F1': {'name': 'ONI2024F1'}})
def test_post_contest(self):

)
self.assertEqual(response.status_code, 201)
self.assertEqual(response.json(), {'id': 'ONI2024F2'})
@patch('OIECApp.views.ContestView.referenceToJson')
def test_get_contest_detail(self, mock_referenceToJson):

mock_doc = MagicMock()
mock_doc.id = 'ONI2024F1'
mock_collection.stream.return_value = [mock_doc]
response = self.client.get(reverse('contest-detail', args=['ONI2024F1']))
self.assertEqual(response.status_code, 200)
self.assertEqual(response.json(), {'ONI2024F1': {'name': 'ONI2024F1'}})
def test_put_contest(self):
mock_collection = self.mock_db.collection.return_value
mock_document = mock_collection.document.return_value
# Mock the update operation
mock_document.update.return_value = None

'name': 'ONI2025F1',
'problems': ['problem1', 'problem3'],
'administratorId': '0987654321'
}
},
format='json'
)
self.assertEqual(response.status_code, 201)
self.assertEqual(response.json(), {'id': 'ONI2025F1'})
def test_delete_contest(self):
mock_collection = self.mock_db.collection.return_value
mock_document = mock_collection.document.return_value
# Mock the delete operation
mock_document.delete.return_value = None
response = self.client.delete(reverse('contest-detail', args=['ONI2024F2']))
self.assertEqual(response.status_code, 204)
这是带有 http 方法的文件：

我认为这可能是 firebase-config 文件，所以我尝试更改它，但随后所有测试都引发了异常。
使用
from firebase_config import dbimport firebase_configfirebase_config.db一旦您
from firebase_config import dbmy_module.dbfirebase_config.db
