- liquibase.extension.testing.testsystem.wrapper.DatabaseWrapper

Direct Known Subclasses:

DockerDatabaseWrapper, JdbcDatabaseWrapper, UnimplementedWrapper
```
public abstract class DatabaseWrapper
extends Object

Wraps the external database used by DatabaseTestSystem so that HOW the database is interacted with is independent of WHAT we do with that connection. For example, the same setup logic can be applied regardless of whether the wrapped database is accessed via JdbcDatabaseWrapper or DockerDatabaseWrapper.
