Thanks, Myrle. This confirms what I've tried so far. The problem may be
an assumed requirement, such as the YAML file and perhaps
/log4j-embedded-cassandra.properties/. But, I'm supplying both of those.
This has something to do with /slf4j/ logging, a logger that has no name
when it goes to get it. It's unclear how it was supposed to get a name.

This will be my second post to this forum : o). We're using embedded
Cassandra in our component tests as a junit ExternalResource, together
with datastax. Here's some of what our start code looks like:
The original code can be found here:
https://github.com/mifosio/test/blob/develop/src/main/java/io/mifos/core/test/fixture/cassandra/CassandraInitializer.java
An example yaml file with the properties requested here can be found:
https://github.com/mifosio/portfolio/blob/develop/service/src/main/resources/application.yml
I use this hundreds of times a day and it works, but because our use
case is kind of special (multi-tenancy via keyspaces and multiple data
stores initialized as TestRules), you may have to noodle through what
we've done a bit to get your stuff working.
Greets,
Myrle

In my (first ever) unit test, I've coded:

EmbeddedCassandraServerHelper.startEmbeddedCassandra( 20000L );

I am following the tutorial at Baeldung. Not sure where to go from here.
Stackoverflow response was not helpful to me, I probably don't know enough
yet.
Thanks.
