Comment on attachment 283064 [details] Patch View in context: https://bugs.webkit.org/attachment.cgi?id=283064&action=review Please explain how this could be testable if we had HTTP tests in TestWebKitAPI > Source/WebKit2/NetworkProcess/NetworkResourceLoader.cpp:409 > + } else if (messageSenderConnection()) > + messageSenderConnection()->send(Messages::WebResourceLoader::DidFailResourceLoad(error), 0, 0); } else if (auto* connection = messageSenderConnection()) connection->send(Messages::WebResourceLoader::DidFailResourceLoad(error), 0, 0);
