So I just made a new thing, and open sourced it.

It’s called the serialization checker. From the readme page it’s here to solve:

The root problem that led to this project's creation is that REST typically uses JSON, and that JSON is Schemaless. This makes it difficult to create data objects to interact with services. In the case of connecting to a third-party REST service, you typically have lots of examples. This project helps you, the developer, iterate through the creation of the data objects.

Where can you find this?

Github page: https://github.com/monksy/serialization-checker

Your project:

<code>resolvers += Resolver.bintrayRepo("monksy","maven")

libraryDependencies += "com.mrmonksy" %% "serialization-checker" % "0.1.3"</code>

Or even it’s Bintray: https://bintray.com/monksy/maven/serialization-checker
