Google App Engine开发服务器如何对数据存储存根？

Question

GAE has a development server that you can use for imitating the "GAE cloud" in local, non-production environments. According to the docs, it mimics all Service API calls.

I'm curious as to how it works with respect to the NoSQL Datastore API. Is there a way to configure your GAE dev server to work with a local database (so you can feed it dummy data that is meaningful to your test cases)? If so how does this work as it is not documented anywhere that I can tell! Thanks in advance!

Answer 1

The development server uses a in-memory key-value store to simulate datastore locally. You can use the --use_sqlite flag to make it work with a local sqlite3 db file instead.

Local unit tests with datastore are documented here

Answer 2

您也可以使用--datastore_path标志将数据存储到文件中，而不是内存中。
