public function DatabaseExceptionWrapperTest::testPrepareStatementFailOnPreparation in Drupal 9

Same name and namespace in other branches

1. 10 core/tests/Drupal/KernelTests/Core/Database/DatabaseExceptionWrapperTest.php \Drupal\KernelTests\Core\Database\DatabaseExceptionWrapperTest::testPrepareStatementFailOnPreparation()

Tests Connection::prepareStatement exceptions on preparation.

Core database drivers use PDO emulated statements or the StatementPrefetch class, which defer the statement check to the moment of the execution. In order to test a failure at preparation time, we have to force the connection not to emulate statement preparation. Still, this is only valid for the MySql driver.
