Examples of testing REST endpoints in Swift

Does anyone have a great example of integration tests written in Swift?

A Google search didn't turn up much. I know by definition what integration tests are, but I'd love to review some well-written tests before I dive in myself.

In other languages/environments the tests look like this: ruby on rails, ruby rspec, nodejs protractor

I found these Swift test examples: vapor, kitura

I use Perfect, but could as well use Kitura or Vapor.
