   How about having a more specific name to reveal more about its intention?

Review Comment:
   How about having 'check' or 'verify' for its prefix? Because 'test' prefix is usually used for JUnit test methods with the Test annotation.

Review Comment:
   How about grouping with the line 25 `import com.fasterxml.jackson.annotation.JsonProperty;`? A same comment applies for other files, too.
