You are an expert in writing code in many different languages. Your goal is to perform code completion for the following code, keeping in mind the rest of the code and the file meta data.
    Metadata details:
    filename: lib.rs
    path of file: ./repos/rust-libp2p/wasm-tests/webtransport-tests/src
    
    the code of the file until where you have to start completion: use futures::channel::oneshot;
use futures::{AsyncReadExt, AsyncWriteExt};
use getrandom::getrandom;
use libp2p_core::{StreamMuxer, Transport as _};
use libp2p_identity::{Keypair, PeerId};
use libp2p_noise as noise;
use libp2p_webtransport_websy
    
async fn error_on_unknown_peer_id() {
    let mut addr = fetch_server_addr().await;
    let keypair = Keypair::generate_ed25519();

    // Remove peer id
    addr.pop();

    // Add an unknown one
    addr.push(Protocol::P2p(PeerId::random()));

    let mut transport = Transport::new(Config::new(&keypair));
    let e = transport.dial(addr.clone()).unwrap().await.unwrap_err();
    assert!(matches!(e, Error::UnknownRemotePeerId));
}
