Question

有人可以提供有关GCP API模拟的帮助吗？这是函数func.py：

import re
from google.cloud import storage
def is_all_log_entries_sink(sink):
    storage_client = storage.Client()
    if 'filter' not in sink and 'storage.googleapis.com' in sink.get('destination', ''):
        bucket_name = re.search(r'^storage.googleapis.com/([^/]+)$', sink.get('destination')).group(1)  
        bucket = storage_client.lookup_bucket(bucket_name)
        if bucket is not None:
            return True
    return False

这是测试：

import mock
from mock import patch, MagicMock
with mock.patch('oauth2client.client.GoogleCredentials.get_application_default') as mock_method:
    import func
@patch('func.storage_client')
def test_is_all_log_entries_sink(mock_obj):
    mock_obj.lookup_bucket = MagicMock(return_value='bucket-name')
    sink = {'name': 'testname', 'destination': 'storage.googleapis.com/bucket-name'}
    assert func.is_all_log_entries_sink(sink) == 1
    assert mock_obj.lookup_bucket.called
    sink = {'name': 'testname', 'destination': 'storage.googleapis.com/bucket-name', 'filter': 'testfilter'}
    assert func.is_all_log_entries_sink(sink) == 0
    sink = {'name': 'testname', 'destination': 'storage.googleapis.com/bucket-name'}
    mock_obj.lookup_bucket = MagicMock(return_value=None)
    assert func.is_all_log_entries_sink(sink) == 0

运行PyTest时，收到以下错误：

E   google.auth.exceptions.DefaultCredentialsError: Could not automatically determine credentials. Please set GOOGLE_APPLICATION_CREDENTIALS or explicitly create credentials and
 re-run the application.

我尝试模拟Google的身份验证，但未成功。任何帮助将不胜感激。

一个可能的解决方案：在os模块中将GOOGLE_APPLICATION_CREDENTIALS模拟为env变量。我认为GOOGLE_APPLICATION_CREDENTIALS是dict，所以嘲笑dict可能会对您有所帮助。
