unit-test-json-serialization

This skill provides patterns for unit testing JSON serialization and deserialization using Spring's @JsonTest and Jackson. It covers testing POJO mapping, custom serializers/deserializers, field name mappings, nested objects, date/time formatting, polymorphic types, and null handling without full Spring context.

JacksonTester not available: Ensure class is annotated with @JsonTest.

Field name doesn't match: Check @JsonProperty annotation and Jackson configuration.

提供使用 Jackson 和 @JsonTest 進行單元測試 JSON 序列化/反序列化的模式。在驗證 JSON 映射、自訂序列化程序和日期格式處理時使用。 來源：giuseppe-trisciuoglio/developer-kit。
