# Test Fixtures
Binary captures of complete TLS 1.3 records used by the integration tests.
| `client_hello_tls13.bin` | RFC 8448 §3, "Simple 1-RTT Handshake" | A single `TLSPlaintext` record wrapping a `ClientHello` for SNI `server`. |
| `server_hello_tls13.bin` | RFC 8448 §3, "Simple 1-RTT Handshake" | A single `TLSPlaintext` record wrapping the matching `ServerHello`. |
RFC 8448 is the IETF's normative reference for TLS 1.3 example traces, so
these fixtures are unambiguously well-formed and free of ambiguity about
what fields the parser should extract.
## Reproducibility
The two files are byte-for-byte copies of the record bytes printed in
RFC 8448 §3. Their SHA-256 digests are recorded here so drift is detectable:
