What could be best approach for regression suite for microservices, Can Scala be used for that?

I was asked to prepare a regression suite for testing micro-services, for that I need to: - Run scripts - Run different API's (can be multiple for scenarios to be used in next API) - Publish result in some presentable format

My own first choice was Jmeter for this, but senior resource didn't agreed and I was asked to use SCALA, while working with Scalatest , I am stuck with Futures as most of my testing revolves around calling Restful API's.

I still think Jmeter is better for what I am doing, but don't have solid base for that, can anyone suggest which one I should go for?
