Question

我想知道如何在模拟中设置域值或值范围。

trait MyInt{
     def getInt():Int
}


trait MyString{
     def getName():String
}

我尝试了一些但没有任何作用。我想定义一个模拟MyInt来返回(0,100)的值和MyString特征从此域返回值：{"Dani",Jonny",Jessica",....}。

我怎么能用scalatest来写呢？

使用mockito plus scalatest

import org.mockito.Mockito._
import org.scalatest.FlatSpec
import org.scalatest.mock.MockitoSugar
import scala.util.Random

class FirstSpec extends FlatSpec with MockitoSugar {

    "The mock" should "pick a value from the interval" in {
        val mockInt = mock[MyInt]
        val mockStr = mock[MyString]

        when(mockInt.getInt()).thenReturn(pickOneFrom(1 to 100 toList))
        when(mockStr.getName()).thenReturn(pickOneFrom(List("Dani", "Jonny", "Jessica")))

        println(mockInt.getInt())
        println(mockStr.getName())

    }

}

其中pickOne将被定义为

def pickOneFrom[T](domain: List[T]) = domain(Random.nextInt(domain.length))
