Review Comment:
Compared with the disadvantage that users cannot tell the test method
directly, I'd rather keep the code clean by wrapping the common logic in a util
method, like `TestUtils#saveAndReload`. I believe a developer should notice
that the `loadServable` is tested in `testLoadServable` by method name.
