Database unit testing (MySQL)

I am trying to find a way to unit test my MySQL dependant code. I know how I would like it to work but cannot find the solution that would work for me. I have looked into DBUnit, but it would seem (if I am not mistaken) that this would require a running database and just aids with the unit testing side of things. I would like some way to avoid running a mysql database when testing. What would work great would be some sort of MySQL spoof driver that actually stored data in memory, rather than needing to access a real persistent database.

In my code it is hard coded to access a MySQL database so I can't just inject some mock object. The way I would like it to work is that when my code calls:

DriverManager.getConnection("jdbc:mysql://" + host + ":" + port + "/" + database, username, password);

It actually gets some other local database that can either be configured via maven or in the setUp of the maven test. I have looked into memory based databases such as HSQLDB but can't find a way for it to spoof the MySQL driver.

Are there any tools that provide what I am looking for? Do you have any good methods for testing MySQL dependant code?

I have had several projects in which I had to do integrations test against a running MySql server. Instead of spending time setting it up every time, I developed a library that sets up a local running instance of MySQL every time you run your tests.

With that you get a test database that acts like the real thing (because it is) without having to set it up.

DBUnit is also a good alternative if you want to mock the database integration (as far as I know, there is no need for a real MySql server when using DBUnit).
