Does Liquibase support dry run?

Question

We have couple of data schemas and we investigate the migration to Liquibase. (One of data schemas is already migrated to Liquibase).

Important question for us is if

Answer 1

If your Liquibase migration is sufficiently database agnostic, you can just run it on an in-memory H2 database (or some other "throwaway database") that you can spin up easily using a few lines of code.

var info = new Properties();
info.put("user", "sa");
info.put("password", "");

try (var con = new org.h2.Driver().connect("jdbc:h2:mem:db", info)) {
    var accessor = new FileSystemResourceAccessor();
    var jdbc = new JdbcConnection(con);
    var database = DatabaseFactory.getInstance().findCorrectDatabaseImplementation(jdbc);

    Liquibase liquibase = new Liquibase("/path/to/liquibase.xml", accessor, database);
    liquibase.update("");
}

I've blogged about this approach more in detail here.
