In this issue, I've already implement almost all methods.
But I've not written tests.

I asked you to finish this issue.

This is a sample for input parameter class that allowed

• "*"
• "none"
• Or any int

sealed abstract class MilestoneSearchOption {
  val value: JValue
}

object MilestoneSearchOption {
  case object All extends MilestoneSearchOption {
    val value = JString("*")
  }

  case object NotAssigned extends MilestoneSearchOption {
    val value = JString("none")
  }

  case class Specified(number: Int) extends MilestoneSearchOption {
    val value = JInt(number)
  }

  def apply(number: Int) = Specified(number)

}
