public function DefaultConfigTest::testConfigIsEmpty in Drupal 9

Same name and namespace in other branches

1. 8 core/tests/Drupal/Tests/Core/Extension/DefaultConfigTest.php \Drupal\Tests\Core\Extension\DefaultConfigTest::testConfigIsEmpty()

Tests that core.extension.yml is empty by default.

The default configuration MUST NOT specify any extensions, because every extension has to be installed in a regular way.

Otherwise, the regular runtime application would operate with extensions that were never installed. The default configuration of such extensions would not exist. Installation hooks would never be executed.
