/**
 * Provides a base class for writing an update test.
 *
 * To write an update test:
 * - Write the hook_update_N() implementations that you are testing.
 * - Create one or more database dump files, which will set the database to the
 *   "before updates" state. Normally, these will add some configuration data to
 *   the database, set up some tables/fields, etc.
 * - Create a class that extends this class.
 * - Ensure that the test is in the legacy group. Tests can have multiple
 *   groups.
 * - In your setUp() method, point the $this->databaseDumpFiles variable to the
 *   database dump files, and then call parent::setUp() to run the base setUp()
 *   method in this class.
 * - In your test method, call $this->runUpdates() to run the necessary updates,
 *   and then use test assertions to verify that the result is what you expect.
 * - In order to test both with a "bare" database dump as well as with a
 *   database dump filled with content, extend your update path test class with
 *   a new test class that overrides the bare database dump. Refer to
 *   UpdatePathTestBaseFilledTest for an example.
