Whenever practical, you should prefer unit tests.

Many tests extend `ESIntegTestCase`, mostly because this is how most tests used
to work in the early days of Elasticsearch. However the complexity of these
tests tends to make them hard to debug. Whenever the functionality that is
being tested isn't intimately dependent on how Elasticsearch behaves as a
