Re: [scalatest-users] Exception messages not printed out with stdout reporter

[Bill Venners]

Hi Sean,

I'm not sure toString is propagated to message. There's a field called message on Throwable, which is what ScalaTest displays (by calling getMessate).

I have the following custom exception 

class HttpRequestException(val response: HttpResponse) extends Throwable {
  ...
  override def toString: String = {
    s"Received unexpected status code. \n Status Code: [${response.status}] \n Body: $body \n Headers: $headers"
  }
}

When this exception is thrown along the stack in my tests, the stdout "-o" reporter only shows the following in the output.

  - test that fails *** FAILED ***

    com.twitter.dataproducts.clients.http.HttpRequestException:

    at com.twitter.dataproducts.clients.akka.Flows$$anonfun$checkResponseForError$1.apply(Flows.scala:25)

    at com.twitter.dataproducts.clients.akka.Flows$$anonfun$checkResponseForError$1.apply(Flows.scala:22)

    at akka.stream.impl.fusing.Map$$anon$8.onPush(Ops.scala:43)

It seems that the exception message is not getting to the proper place here. I am sure I am doing something wrong. Any help would be appreciated.

When working with this, I also have tried to override getMessage on Throwable with the same implementation as the override from toString above, and the result is the same.

This seems to be the line for the StringReporter. I am trying to dig in to see why it's not working properly, but that will take me some time.
