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]

Answer 1

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.
