Hello!

We're using ES 7.6.2 (pull document and upload bulks).  
And we want to create tests, as data is upload correctly, simulate situations where the bulk (/ connection, etc.) is failed.

I found old [reference](https://stackoverflow.com/questions/47466064/in-memory-elastic-search) to Elastic In memory that it's not supported at the answer time (2017)  
And I want to ask if it's support toady, in the latest version? if not, does there is another way to mock ES?

Thank you!!

No, this kind of mock is not provided. I'd recommend using a real cluster so that you get the real behaviour rather than trying to build such a mock.
