google-api - 模拟访问公共(public) GCS 存储桶的结果

Question

我有以下代码:

bucket = get_bucket('bucket-name')
blob = bucket.blob(os.path.join(*pieces))
blob.upload_from_string('test')
blob.make_public()
result = blob.public_url
# result is `<Mock name='mock().get_bucket().blob().public_url`

我想模拟public_url的结果，我的单元测试代码是这样的

with ExitStack() as st:
    from google.cloud import storage
    blob_mock = mock.Mock(spec=storage.Blob)
    blob_mock.public_url.return_value = 'http://'

    bucket_mock = mock.Mock(spec=storage.Bucket)
    bucket_mock.blob.return_value = blob_mock

    storage_client_mock = mock.Mock(spec=storage.Client)
    storage_client_mock.get_bucket.return_value = bucket_mock

    st.enter_context(
        mock.patch('google.cloud.storage.Client', storage_client_mock))
    my_function()

有没有类似 FakeRedis 的东西或 moto用于 Google 存储，所以我可以模拟 google.cloud.storage.Blob.public_url ?

我找到了 fake gcs server用 Go 编写，可以在 Docker 容器中运行并由 Python 库使用。见 Python examples .
