When running Magento 2 unit tests via dev:tests:run
unit I get an error. This is magento 2 out of the box.
PHP Fatal error: Class Magento\Catalog\Api\Data\ProductExtension contains 12 abstract methods and must therefore be declared abstract or implement the remaining methods (Magento\Catalog\Api\Data\ProductExtensionInterface::getBundleProductOptions, Magento\Catalog\Api\Data\ProductExtensionInterface::setBundleProductOptions, Magento\Catalog\Api\Data\ProductExtensionInterface::getDownloadableProductLinks, ...) in /var/www/dev/tests/unit/tmp/var/generation/Magento/Catalog/Api/Data/ProductExtension.php on line 7
