The latest changes in Patrol v2.3.0 have renamed some of these classes.

You need to rebuild your generated classes after upgrading, e.g. just run patrol test again.

For info, some classes changed, e.g. DartTestGroup is now DartGroupEntry.

You can glean the changes from this file packages/patrol_cli/lib/src/test_bundler.dart when viewing the changeset for v2.3.0
