If you enable CentralAuth but don't have SecurePoll installed and run CentralAuthExtensionJsonTest, it will fail:
1) CentralAuthExtensionJsonTest::testHookHandler with data set #11 ('securepoll') Error: Interface "MediaWiki\Extension\SecurePoll\Hooks\SecurePoll_GetUserParamsHook" not found /var/www/html/w/extensions/CentralAuth/includes/Hooks/Handlers/SecurePollHookHandler.php:30 /var/www/html/w/includes/AutoLoader.php:222 /var/www/html/w/vendor/wikimedia/object-factory/src/ObjectFactory.php:240 /var/www/html/w/vendor/wikimedia/object-factory/src/ObjectFactory.php:149 /var/www/html/w/tests/phpunit/integration/includes/ExtensionJsonTestBase.php:97 /var/www/html/w/tests/phpunit/MediaWikiIntegrationTestCase.php:518
