class StubPDO in Zircon Profile 8

Same name and namespace in other branches
  1. 8.0 core/tests/Drupal/Tests/Core/Database/Stub/StubPDO.php \Drupal\Tests\Core\Database\Stub\StubPDO

A stub of \PDO for testing purposes.

We override the constructor method so that PHPUnit can mock the \PDO class. \PDO itself can't be mocked, so we have to create a subclass. This subclass is being used to unit test Connection, so we don't need a functional database but we do need a mock \PDO object.
