External Python packages interfacing beets may want to use an in-memory beets library instance for testing beets-related code. The `TestHelper` class is very helpful for this purpose. Previously `TestHelper` was located in the `test/` directory. Now it is part of `beets` itself (`beets.test.helper.TestHelper`) and can be easily imported.
