SPDM Loopback Integration Tests

This test application validates SPDM protocol implementation using in-memory MCTP loopback transport.

Overview

Tests SPDM requester ↔ responder communication without hardware dependencies by using:

• MctpSpdmTransport with LoopbackClient from mctp-transport-loopback
• Mock platform implementations for cryptographic operations
• Pre-fabricated SPDM messages with assertion-based validation

Tests

1. GET_VERSION - SPDM version negotiation
2. GET_CAPABILITIES - Device capability discovery
3. NEGOTIATE_ALGORITHMS - Cryptographic algorithm selection
