/**
 * Test deprecation error handling by DrupalStandardsListener.
 *
 * DrupalStandardsListener has a dependency on composer/composer, so we can't
 * test it directly. However, we can create a test which is annotated as
 * covering a deprecated class. This way we can know whether the standards
 * listener process ignores deprecation errors.
 *
 * Note that this test is annotated as covering
 * \Drupal\deprecation_test\Deprecation\FixtureDeprecatedClass::testFunction(),
 * but the reason the test exists is to cover
 * \Drupal\Tests\Listeners\DrupalStandardsListener::endTest(). We never
 * actually instantiate
 * \Drupal\deprecation_test\Deprecation\FixtureDeprecatedClass because that
 * would trigger another deprecation error.
