My preference is for Scala projects to keep all code in Scala unless there's a major force (i.e. lack of equivalent enums in Scala that can be injected into).

If we focus on this specific case, unless there's a huge rush to integrate the test, this is a chance for the contributor (Michal) to get familiar with another programming language, which I think is a really good thing.
