I apologize if I'm missing something simple, but I'm trying to use Akka HTTP with Circe (using the akka-http-json Circe module). I'm trying to retrieve the results of a GET call in a ScalaTest which mixes in the ErrorAccumulatingCirceSupport trait. The call goes through successfully, but I'm unable to unmarshal the response...It's a pretty simple test, but I'm just not sure how to unmarshal the results into a list of domain objects, eg:
Get("/path/to/getfoos").withHeaders(auth) ~> Route.seal(service.route) ~> check {
import io.circe.generic.auto._
status shouldEqual StatusCodes.OK
contentType should ===(ContentTypes.`application/json`)
val reports = responseAs[List[Foo]]
reports.size shouldBe 1
}
The error I'm getting is:
Could not unmarshal response to type 'scala.collection.immutable.List' for `responseAs` assertion: de.heikoseeberger.akkahttpcirce.ErrorAccumulatingCirceSupport$DecodingFailures: DecodingFailure at [0]: CNil
If anyone can point out what I'm dong wrong I would very much appreciate the help!
Thanks!
I'm not sure if this is the best way, but I was able to get my case classes unmarshalled using something like the following; if there's better way, please let me know!
val entity = responseEntity
val foos: List[Foo] = Unmarshal(entity).to[List[Foo]].futureValue
foos(0) shouldBe expectedFoo
foos.size shouldBe 1
(Note that I had to also mixin the org.scalatest.concurrent.ScalaFutures trait)
