Subject Re: How to tear down an EmbeddedCassandraService in unit tests?
Date Fri, 28 Mar 2014 19:05:13 GMT
We are using version 1.2.4 and it is difficult to shutdown the embedded
version. But you don't have to. Just check in each test setup method if
embedded Cassandra is already running and start it if necessary. Than
create keyspaces/tables in setup methods and drop them in teardown methods.
For us this is also faster.

A nice alternative is: https://github.com/edwardcapriolo/farsandra

We also use Farsandra and it works pretty well.
