// Test Data for Parse/WriteMessages:
// * Name: A string name that is used when reporting the test (it's the ToString value for ProtocolTestData)
// * Message: The HubMessage that is either expected (in Parse) or used as input (in Write)
// * Encoded: Raw MessagePackObject values (using the MessagePackHelpers static "Arr" and "Map" helpers) describing the message
// * Binary: Base64-encoded binary "baseline" to sanity-check MsgPack-Cli behavior
//
// The Encoded value is used as input to "Parse" and as the expected output that is verified in "Write". So if our encoding changes,
// those values will change and the Assert will give you a useful error telling you how the MsgPack structure itself changed (rather than just
// a bunch of random bytes). However, we want to be sure MsgPack-Cli doesn't change behavior, so we also verify that the binary encoding
// matches our expectation by comparing against a base64-string.
//
// If you change MsgPack encoding, you should update the 'encoded' values for these items, and then re-run the test. You'll get a failure which will
// provide a new Base64 binary string to replace in the 'binary' value. Use a tool like https://sugendran.github.io/msgpack-visualizer/ to verify
// that the MsgPack is correct and then just replace the Base64 value.
