Python 3.x 如何测试google驱动API python客户端
我目前在django项目中有一个GoogleDriveAPI客户端,它可以正常工作Python 3.x 如何测试google驱动API python客户端,python-3.x,python-unittest,google-drive-realtime-api,Python 3.x,Python Unittest,Google Drive Realtime Api,我目前在django项目中有一个GoogleDriveAPI客户端,它可以正常工作 import unittest from unittest import mock DRIVE_API_VERSION = "v3" DRIVE_API_SERVICE_NAME = "drive" DRIVE_AUTHORIZED_USER_FILE = "path/to/secrets/json/file" DRIVE_SCOPES = ['https://www.googleapis.com/auth/d
import unittest
from unittest import mock
DRIVE_API_VERSION = "v3"
DRIVE_API_SERVICE_NAME = "drive"
DRIVE_AUTHORIZED_USER_FILE = "path/to/secrets/json/file"
DRIVE_SCOPES = ['https://www.googleapis.com/auth/drive', 'https://www.googleapis.com/auth/drive.file ', 'https://www.googleapis.com/auth/drive.appdata']
def construct_drive_service():
try:
drive_credentials = google.oauth2.credentials.Credentials.from_authorized_user_file(
DRIVE_AUTHORIZED_USER_FILE, scopes=DRIVE_SCOPES)
except FileNotFoundError:
print('Drive credentials not created')
pass
if drive_credentials:
return build(DRIVE_API_SERVICE_NAME, DRIVE_API_VERSION, credentials=drive_credentials, cache_discovery=False)
else:
return None
我现在面临的挑战是为这个函数编写测试。但我不知道该用什么策略。我试过这个
class TestAPICalls(unittest.TestCase):
@mock.patch('api_calls.google.oauth2.credentials', autospec=True)
def setUp(self, mocked_drive_cred):
self.mocked_drive_cred = mocked_drive_cred
@mock.patch('api_calls.DRIVE_AUTHORIZED_USER_FILE')
def test_drive_service_creation(self, mocked_file):
mocked_file.return_value = "some/file.json"
self.mocked_drive_cred.Credentials.return_value = mock.sentinel.Credentials
construct_drive_service()
self.mocked_drive_cred.Credentials.from_authorized_user_file.assert_called_with(mocked_file)
但是我的测试失败了,错误如下
with io.open(filename, 'r', encoding='utf-8') as json_file:
ValueError: Cannot open console output buffer for reading
我知道客户端正在尝试读取文件,但却得到了一个模拟对象
。问题是我不知道该怎么办
解决这个问题
我一直在阅读mock
库,但整个过程仍然模糊不清 见:
