最近开始在 Scala 中编码，我尝试编写一些基于属性的测试用例。在这里，我试图生成模仿我正在测试的系统的原始数据。目标是首先生成基本元素（ctrl和idz），然后使用这些值生成两个类（A1和B1），最后检查它们的属性。我首先尝试了以下方法 -

import org.scalatest._
import prop._
import scala.collection.immutable._
import org.scalacheck.{Gen, Arbitrary}

case class A(
    controller: String,
    id: Double,
    x: Double
)

case class B(
    controller: String,
    id: Double,
    y: Double
)

object BaseGenerators {
    val ctrl = Gen.const("ABC")
    val idz = Arbitrary.arbitrary[Double]
}

trait Generators {
    val obj = BaseGenerators

    val A1 = for {
        controller <- obj.ctrl
        id <- obj.idz
        x <- Arbitrary.arbitrary[Double]
    } yield A(controller, id, x)

    val …
