// The tests in this file use a pre-recorded AuthChallenge as input and a
// matching pre-recorded AuthResponse for verification.  This is to make it
// easier to keep sender and receiver code separate, because the code that would
// really generate an AuthChallenge and verify an AuthResponse is under
// //cast/sender.  The pre-recorded messages come from an integration test which
// _does_ properly call both sender and receiver sides, but can optionally
// record the messages for use in these unit tests.  That test is currently
// under //cast/test.  See //cast/test/README.md for more information.
//
// The tests generally follow this procedure:
//  1. Read a fake device certificate chain + TLS certificate from disk.
//  2. Read a pre-recorded CastMessage proto containing an AuthChallenge.
//  3. Send this CastMessage over a CastSocket to a DeviceAuthNamespaceHandler.
//  4. Catch the CastMessage response and check that it has an AuthResponse.
//  5. Check the AuthResponse against another pre-recorded protobuf.
