crates/starknet_http_server/src/http_server_test.rs line 73 at r1 (raw file):

    let HttpServerConfig { ip, port } = http_server_config;
    let add_tx_http_client = HttpTestClient::new(SocketAddr::from((ip, port)));

Wouldn't it be better to define http_server_socket = SocketAddr::from(("127.0.0.1", 15123)) once, and then use the create_http_server_config function to generate the http_server_config?

Code quote:

    let http_server_config = HttpServerConfig { ip: "127.0.0.1".parse().unwrap(), port: 15123 };
    let mut http_server =
        HttpServer::new(http_server_config.clone(), Arc::new(mock_gateway_client));
    tokio::spawn(async move { http_server.run().await });

    let HttpServerConfig { ip, port } = http_server_config;
    let add_tx_http_client = HttpTestClient::new(SocketAddr::from((ip, port)));
