Question

I am using ScalaMock 3.0 with ScalaTest and Scala 2.10. When I try to mock a class that inherits from java.io.File I get the following compliation error. method getPrefixLength overrides nothing

Here is some sample code:

class TrendSpec extends FunSpec with MockFactory {
  class A extends java.io.File("")
  val a = mock[A]
}

Is there anyway of working around this?

Answer 1

The problem is that getPrefixLength is package private, but the reflection API seems to be broken for package private variables. There’s an ongoing discussion on the scala-user mailing list about this.

Please do report this as a bug on the ScalaMock bug tracker
