unit-test-json-serialization skillA

unit-test-json-serialization is agent-read markdown (skill) from giuseppe-trisciuoglio/developer-kit: Provides patterns for unit testing JSON serialization/deserialization with Jackson and `@JsonTest`. Validates JSON mapping, custom serializers, date formats, and polymorphic types. Use when testing JSON serialization, validating custom serializers, or writing JSON unit tests in Spring Boot applications..

Indexed from public GitHub and served as immutable, content-addressed versions. Install it pinned to an exact SHA-256 with the mdr CLI, and every file is verified against the hash recorded here before it reaches your agent. The deterministic audit below grades the latest version, and the same file always earns the same grade.

How to install

Latest version
mdr add giuseppe-trisciuoglio/developer-kit/unit-test-json-serialization@git:20260324.a02e282
Exact content
mdr add giuseppe-trisciuoglio/developer-kit/unit-test-json-serialization@sha256:d874bbbd2bb7c42e

Pin to a label to follow the author's releases, or to a sha256 to freeze the exact bytes forever. Either way the resolved hash is written to mdr.lock, and mdr install reproduces it on any machine.
