public function YamlTest::testYamlFiles in Drupal 9

Same name and namespace in other branches

1. 8 core/tests/Drupal/Tests/Component/Serialization/YamlTest.php \Drupal\Tests\Component\Serialization\YamlTest::testYamlFiles()

Tests all YAML files are decoded in the same way with Symfony and PECL.

This test is a little bit slow but it tests that we do not have any bugs in our YAML that might not be decoded correctly in any of our implementations.

@todo This should exist as an integration test not part of our unit tests. https://www.drupal.org/node/2597730
