Document how to use TestRestTemplate with spring-data-rest

TestRestTemplate is relatively popular in the spring world but it's not obvious how to use it with the spring-data-rest CrudRepository generated endpoints. spring-data-rest wraps every response in an object I didn't create. It's not obvious how to use TestRestTemplate with this object unless I return simple response classes like String or Map<?, ?>.

1. • If TestRestTemplate can be used with spring-data-rest, please provide examples of using it with response bodies more complex than String or Map<?, ?>. e.g., a Person class.
2. • Please also include a postForEntity and/or putForEntity(putForEntity doesn't exist) example, because I see a lot of people struggling to make requests that send a complex class, e.g., Person, in the request body.
3. • If TestRestTemplate is the wrong tool for the job, please recommend the right tool or a better tool. This might already be documented, but I've been unable to find it.

Thanks,
Dan
