TDD Getters and Setters in Scala

Question

Test

package com.utrecht.numbersequences

import org.scalatest.FunSuite
import org.scalatest.BeforeAndAfter
import org.scalatest.mock.MockitoSugar
import org.mockito.Mockito._

class NumberSequencesTests extends FunSuite with BeforeAndAfter with MockitoSugar {
  test("testCity") {
    NumberSequences.city_("utrecht")
    assert("utrecht" === NumberSequences.city())
  }
}

Code

package com.utrecht.numbersequences

import scala.collection.immutable.Stream.consWrapper

object NumberSequences {
  var _city: String = null 

  def city_=(_city:String) = this._city = _city  
  def city = this._city
}

Outcome

value not a member of object
not enough arguments for method apply: (index: Int)Char in class StringOps

NumberSequences.city_=("utrecht")
//OR
NumberSequences.city = "utrecht"

but not:

NumberSequences.city_("utrecht") // city_ is not a method existing in the object
