+ * 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 handles deprecation errors properly.
+ *
+ * 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.
+ *
