I did a couple related blog posts a while ago at http://blog.liquibase.org/2007/06/building-database-tests-that-dont-brea k.html.
I have always used liquibase both liquibase and mysqldump for managing my test datasets, and both work well. Keeping it all in liquibase changelogs makes it easy to create different "contexts" in which different datasets are loaded. As your database gets larger and more complex, however, it becomes much easier to manage your database with your application and make backups from time to time to use as your testing dataset. The reason we use an XML format is primarily because you get intellisense support in your IDE from the XML schema. You do get database independence, but you would get that with any sort of DSL description of your changes.

Hi all, I am investigating which tool to use to create exact database snapshots that are loaded into a database befpre some JUnit tests are run. The goal is to have the exact same data present for each test run. So I read on the liquibase homepage that I can create test datasets. I also know about DBUnit, which also exports a snapshot to a xml file. Maybe someone can explain what he thinks is the best way of doing these things. We have a MySQL database and the DB including data is not very big. - Why not use mysqldump one the test data has been created and import the db before each test run? Isn't that the easiest solution? - Why does both DBUnit and Liquibse save the dataset as XML. It is meant to be database-agnostic, but we won't change our DB (and I doubt hardly one does) in the foreseeable future. Woudl it mean doing an dump is really the best option or am I a forgetting an important point?
