Running functional routing tests for play-mini yields "Cannot init the Global object [null]"

[SP]

Hi,

I am attempting to write functional tests to validate the routes of an
play-mini(ied) application. It looks like the following:

package my.awesome.package
import com.typesafe.play.mini.{POST, GET, DELETE, Path,
Application => PlayApplication}
//.... whole lot of other play.api imports ...

object BlaServiceApi extends PlayApplication {
def route = {
case POST(Path("/bla")) => Action { .... }
case GET(Path("/bla")) => Action { .... }
}
}

in my default package scope Global.scala I have:

import com.typesafe.play.mini.Setup
object Global extends Setup(my.awesome.package.BlaServiceApi)


So far so good. I can run this great (after I fixed my version
dependencies last week). Awesome.

Now the router functional tests I am writing look like this:

package my.awesome.package
import org.specs2.mutable._
import play.api.test.{Helpers => PlayHelpers, _}
import play.api.test.Helpers.{GET, POST, PUT, DELETE}

class BlaServiceApi extends SpecificationWithJUnit {
"GET /bla" should {
"respond with a success (OK)" in {
PlayHelpers.running(FakeApplication()) {
val result = PlayHelpers.routeAndCall(FakeRequest(GET, "/
bla")).get
PlayHelpers.status(result) must equalTo(PlayHelpers.OK)
}
}
}
}

Now the test compiles, but when running the test it yells at me with
this lovely stack trace (oh, how I forgot your lovely stack traces
Java/JVM):

Should I be setting things up with something other than an instance of
play.api.test.FakeApplication as argument to the running Play test
helper method that is special to play-mini wrapper code?

Is there any documentation on this so far? I have been using the Akka
HTTP module documentation section of the PDF for reference (v2.0-RC2)
on the main code and the Play 2.0 GitHub wiki page for the functional
test code:
https://github.com/playframework/Play20/wiki/JavaFunctionalTest

Any pointers to play-mini functional test examples would be fantastic.

Thanks,
SP

Hi,
There's no documentation on this topic so far.
I have not tested it, but will try it out and we will get back to you asap.
Cheers
