elasticsearch embedded in Node.js

Question

我是Node.js开发的新手，我想知道是否有一种方法可以将ElasticSearch嵌入Node.js应用程序中进行测试，或者是否有另一种方法可以测试与ElasticSearch的交互，而无需运行ElasticSearch实例（mock ？）

Answer 1

There are no existing mock libraries for Elasticsearch and Node at the moment. If you know exactly what queries you are going to be performing, you could use a mocking library to mock the entire ES client and assert simple behaviors.

What I'd recommend, however, is actually running ES in a development environment for testing. I find that mocking external services is a pretty tricky thing to do in general, and your tests will likely be much more robust / trustworthy if running against an actual instance of the server.
