Re: Running Cassandra in Integration Tests

[Matteo Moci]

Sorry for bumping this old thread, but what would be your suggestion for
programmatically start/stop nodes in a cluster?

I'd like to make some experiments and perform QUORUM writes against a
cluster (REPLICATION=3) with alternatively 2 or 3 nodes up,
starting/stopping/restarting nodes in the middle, etc...  to understand the
behaviour.

Re: Running Cassandra in Integration Tests

[Eric Stevens]

If you happen to be using Scala, we recently released some tooling we wrote
around using CCM for integration testing:
https://github.com/protectwise/cassandra-util

You define clusters and nodes in configuration, then ask the service to go:
https://github.com/protectwise/cassandra-util/blob/master/ccm-testing-helper/src/main/scala/com/protectwise/testing/ccm/CassandraSetup.scala#L147

It'll create your clusters and tear them down automatically when execution
completes.

Checkout https://github.com/edwardcapriolo/farsandra. It falls under the
realm of almost 100% pure java (besides the fact it uses some shell to
launch Cassandra).

Re: Running Cassandra in Integration Tests

[Jonathan Haddad]

3.9 falls under the Tick Tock release cycle, which is almost completely
untested in production by experienced operators.  In the cases where it has
been tested, there have been numerous bugs found which I (and I think most
people on this list) consider to be show stoppers.  Additionally, the Tick
Tock release cycle puts the operator in the uncomfortable position of
having to decide between upgrading to a new version with new features
(probably new bugs) or back porting bug fixes from future versions
themselves.There will never be a 3.9.1 release which fixes bugs in 3.9
without adding new features.

https://github.com/apache/cassandra/blob/trunk/NEWS.txt

For new projects I recommend starting with the recently released 3.0.9.

Assuming the project changes it's policy on releases (all signs point to
yes), then by the time 4.0 rolls out a lot of the features which have been
released in the 3.x series will have matured a bit, so it's very possible
4.0 will stabilize faster than the usual 6 months it takes for a major
release.

All that said, there's nothing wrong with doing compatibility & smoke tests
against the latest 3.x release as well as 3.0 and reporting bugs back to
the Apache Cassandra JIRA, I'm sure it would be greatly appreciated.

Our application takes care of creating keyspace and tables as necessary. Our 
tests didn't need to worry about that.

Akthar,
We use 2.2.4.

I am not sure if cassandra.config can take a classpath. Feel free to try. It 
was easy enough to copy the resource to temp file location for us.

Re: Running Cassandra in Integration Tests

[Peddi, Praveen]

Honestly there isn't much code to share. Here is the code (excluded exception 
handling). For yaml location, we have the classpathpath and write to temp 
location everytime.

System.setProperty("cassandra.config", "file://" + YAML_LOCATION);
cassandraDaemon = new CassandraDaemon();
 cassandraDaemon.init(null);
cassandraDaemon.start();

//stop cassandra after tests are done
cassandraDaemon.stop();

Also, which version of cassandra are you doing that with?

That looks great Andrew, but it doesn't seem to have been committed to for 5 
months. Is anyone still using cassandra-unit , does it work with latest 
cassandra versions (e.g 3.9)?

Re: Running Cassandra in Integration Tests

[Kant Kodali]

embedded cassandra instance? you mean dont persist any data to disk? If so I
dont see that being possible at this time. prior to running your test code you
just run shell script and after test truncate everything and bring down the
instance. one way or other this needs to happen underneath so I dont see how you
could bypass that whichever way you may choose.

Hi Ali,

cassandra-unit  might be what
you are looking for.  It allows you to run an embedded cassandra instance
along side your tests and has some nice integration with JUnit.

Re: Running Cassandra in Integration Tests

Ok, but that's not what this question is about.

I'm looking for a way to run an embedded cassandra instance which is
created & destroyed during tests and which doesn't persist any state
outside the tests.
