How do I mock static function (Object function, not class function) in scala

Question

Object A {
  def a = { something}
}

// I've import A, but still have error message:  not found: type A
val x = mock[A]

The type of `object A` is `A.type`. If you want to define type `A`, you need to e.g. define `class A { /* as now */ }` and then `object A extends A`. — Jean-Philippe Pellet, Apr 17 '11 at 22:29

You don't. Not only A is not a type or class -- it is an instance -- but it is an instance of a singleton (A.type).

What you do instead is put your methods on a trait, and make the object extend it. Then, you mock the trait instead of mocking the object.

You may find this email thread instructive.

Whilst pure mocking of the object is not possible with any tool yet, the thread above does have a few options for you. All of which involve changing your design to some degree.
