Hi @ianbrandt I'm trying to utilize TDD in a Kotlin spring boot project. I'm using data classes for my POJOs. Is there any reason to unit test a data class? It literally just has a primary constructor and it's data fields. No business logic, no methods.

it would make sense to add tests for POJOs only if you have a custom implementation for
equals
or id you are adapting the POJO from some other class

I suppose you could write an equals, hashCode, and toString smoke test to express the intent that it stays a data class? I’ve used https://jqno.nl/equalsverifier/ to do that with minimal code for Java DTOs in the past. I haven’t tried it with Kotlin yet. If you give it a shot and it works well, or doesn’t, I’d love to hear.

Very cool, thanks! These data classes will always remain data classes in this project. However you're right anything can happen, and someone could theoretically change that
