-For users integrating and testing compressjson in various scenarios (e.g., handling specific errors, simulating compression/decompression outcomes), the repository includes a dedicated transcoder mock pkg that provides the MockTranscoder implementation. This facilitates robust unit testing and integration testing without requiring actual Zstd operations.
