Meet up

Stubbed Cassandra and 6 Lightning Talks!

Wednesday, 20th August at Skills Matter, London

This meetup was organised by Cassandra London in August 2014


Cassandra is great but how do I test my application?

In this talk Christopher will talk about how to test your applications that use Cassandra.

Starting at the unit test level through to the black box acceptance tests. Most of the talk will be around a new framework, Stubbed Cassandra (, that has been developed that stubs Cassandra so that all failure scenarios can be deterministically reproduced without having to create a multi node cluster.
