Integration Testing with Redis

I've started using Redis in my project with the help of the Jedis library. All is working fine but now I have a problem that my functional tests requires Redis to be up which I want to avoid in my Continuous Integration. What is the best way to do this?

Here are few options you have for functional/integration testing:

1. Just start an instance of redis on you CI server. All tests will be responsible to do proper clean up after execution.
2. Try somehow to control redis process, i.e. have some shell script or job on CI server to start/stop it before/after running tests. At least some of the burden of setup/cleanup is removed from tests, as for each independent build you will have independent redis setup.
3. Control redis further by using some in-memory solution like the one you mention for cassandra(if it exists).

One thing to mention is that integration tests should not replace unit tests. Unit tests should probably be preferred and they can cover more cases whereas integration tests can be used just to check that all parts of application play nicely together. And i think this is the reason why a lot of people choose to go for option number one.

Here is a similar question about mongodb The answer has a link to the project which works for second option(controls mongodb process) If you follow some related links on the project page there's also something called nosql-unit. This one i think tries to cover option three. I didn't use it but looks like it has something for redis too.
