// Test works by using a slice of interfaces.
// It can test for encoding/decoding into/from a nil interface{}
// or passing the object to encode/decode into.
//
// There are basically 2 main tests here.
// First test internally encodes and decodes things and verifies that
// the artifact was as expected.
// Second test will use python msgpack to create a bunch of golden files,
// read those files, and compare them to what it should be. It then
// writes those files back out and compares the byte streams.
//
// Taken together, the tests are pretty extensive.
//
// The following manual tests must be done:

// TODO:
//   Add Tests for:
//   - decoding empty list/map in stream into a nil slice/map
//   - binary(M|Unm)arsher support for time.Time (e.g. cbor encoding)
//   - text(M|Unm)arshaler support for time.Time (e.g. json encoding)
//   - non fast-path scenarios e.g. map[string]uint16, []customStruct.
//     Expand cbor to include indefinite length stuff for this non-fast-path types.
//     This may not be necessary, since we have the manual tests (fastpathEnabled=false) to test/validate with.
//   - CodecSelfer
//     Ensure it is called when (en|de)coding interface{} or reflect.Value (2 different codepaths).
//   - interfaces: textMarshaler, binaryMarshaler, codecSelfer
//   - struct tags:
//     on anonymous fields, _struct (all fields), etc
//   - codecgen of struct containing channels.
//   - bad input with large array length prefix
//
//   Cleanup tests:
//   - The are brittle in their handling of validation and skipping
