## Test loop - Happy path
- Start a relay `cargo run --bin quic_demo_relay_server`
- Start a relay `cargo run --bin ptth_quic_relay_server`
- Verify that the relay has no end servers connected
- Start an end server `cargo run --bin quic_demo_end_server -- --debug-echo`
- Start an end server `cargo run --bin ptth_quic_end_server -- --debug-echo`
- Verify that the end server connected
- Start a client `cargo run --bin quic_demo_client`
- Start a client `cargo run --bin ptth_quic_client`
- Connect to the client and verify that the debug echo server is running
