Core Features Tested

Feature	code	details
Version Negotiation	V	A version negotiation response is elicited and acted on
Handshake	H	The handshake completes successfully
Stream Data	D	Stream data is being exchanged and ACK'ed
Connection Close	C	The connection close procedure completes w/a zero error code
Resumption	R	Connection is established using TLS Resume Ticket
0-RTT	Z	0-RTT data is being sent and acted on
Stateless Retry	S	A handshake that includes a Retry packet completes successfully
Migration	M	A new CID is offered to the peer, and it migrates the connection to it
Rebinding	B	The client moves to a different address or port, and the server migrates to it
Key Update	U	One endpoint can update keys and its peer responds correctly
H3	3	An H3 transaction succeeded
Spin	P	A connection with the spin succeeds and the bit is spinning
ECN	E	Set ECT(0) on outgoing packets and verify that ACK frames with ECN information are received. (Note: test can fail if path bleaches ECN)

Perf Features Tested

|Throughput | T | Download objects named 5000000 and 10000000 on separate connections over both HTTP/2 and HTTP/3 (0.9 if H3 not available). Overall transfer time should be no worse than 10% slower than HTTP/2. |
