In-memory Cassandra db for Python driver object mapper 'cqlengine'

[Swati]

Hi,

I am using Python driver's object-mapper 'cqlengine' for interacting with Cassandra db. I was looking for in-memory implementation of the same, for performing unit testing. Please advice how to go ahead about it, any libraries to use and any examples.

Thanks,
Swati

Swati,

I'm afraid I don't know of anything that would meet those exact requirements. Typically we use a combination of the python mock libraries, and CCM for our testing. Using the mock libraries might be a bit of work but it will likely give you your best results for unit testing. Using ccm will be easier to get going with, but we use it more for integration testing. The ccm git repo is located here https://github.com/pcmanus/ccm.

~Thanks

I developed a crude in-memory CQLengine mocking 2 years ago. I might try to open-source it in the next few week if anybody's interested.
