Most lightweight webservice framework to mock external Webservice in Scala

I am trying to test a component which relies on an external webservice, which I access through Play WS library. This components receive the url of the webservice.

I would like to unit test the component by getting it connected to a fake webservice.

Which scala web frameworks would be more suitable for the purpose?

Solution

  • I failed to find something simplier than scalatra. Although code on main page is really simple you would have to do some extra work to embed scalatra in your own app/tests. 

    import org.scalatra._
import org.eclipse.jetty.server.Server
import org.eclipse.jetty.webapp.WebAppContext

private class Mocker extends ScalatraServlet {
    get("/somepath") {
      <h1>Mocked response</h1>
    }
  }

// ↓ you won't need that part if you start jetty as sbt command

private val jetty = new Server(8080)
private val context = new WebAppContext()
context setContextPath "/"
context setResourceBase "/tmp"
context addServlet(classOf[Mocker], "/*")

jetty.setHandler(context)
jetty.start

    Standalone app is really that simple.
