英文:
Disable google cloud authentication python when mocking google.cloud.storage
问题
以下是您要翻译的部分：
从以下的Google Cloud Storage模拟开始
```python
from google.cloud import storage
class MockBlob:
def download_as_string(self) -> bytes:
return bytes("\n".join(INPUT_IDS), "utf-8")
class MockBucket:
def get_blob(self, path: str) -> MockBlob:
return MockBlob()
class MockStorageClient(storage.Client):
def __init__(self, *args, **kwargs):
super().__init__(*args, **kwargs)
def _require_client_info(self, client_info=None):
pass
def _require_virtual(self):
pass
def get_bucket(self, bucket_or_name: str):
return MockBucket()
我收到以下错误消息

测试的目的是查看是否使用存储桶的代码是否正常工作。获取的Blob包含一个由"\n"分隔的文本文件中的ID，这就是下载函数返回静态字节字符串的原因。
如何禁用凭据以避免出现问题。

The purpose of the test is to see if the code utilizing the bucket is working. The blob that is fetched contains a text file of ids that are separated by "\n", which is why the download function returns a static byte string.
How do i disable the credentials, such that it is not an issue.

以下是翻译好的部分：
您可以简单地覆盖失败的函数，如下所示：
```python
from google.auth import credentials
import google.auth._default
def load_credentials_from_file(
filename, scopes=None, default_scopes=None, quota_project_id=None, request=None
) -> Tuple[credentials.Credentials, Optional[str]]:
return (credentials.AnonymousCredentials(), "test-project")
google.auth._default.load_credentials_from_file = load_credentials_from_file
<details>
<summary>英文:</summary>
You can simply override the function that fails as
```python
from google.auth import credentials
import google.auth._default
def load_credentials_from_file(
filename, scopes=None, default_scopes=None, quota_project_id=None, request=None
) -> Tuple[credentials.Credentials, Optional[str]]:
return (credentials.AnonymousCredentials(), "test-project")
google.auth._default.load_credentials_from_file = load_credentials_from_file
