Specs2和scalacheck - 必须通过问题

Question

我收到not found: value pass以下代码段的错误.
我是否会错过任何导入或此代码对specs2无效？

import org.specs2.mutable.Specification
import org.specs2.ScalaCheck
import org.scalacheck.{Prop, Gen}

class TestSpec extends Specification with ScalaCheck {
  "Calling test spec" should {
    "always pass" in {  
      val prop = Prop.forAll((a:Int) => true)
      prop must pass
    }
  }
}

Answer 1

must pass是原始规格项目中使用的东西.使用specs2,你可以简单地写:

import org.specs2.mutable.Specification
import org.specs2.ScalaCheck
import org.scalacheck.{Prop, Gen}

class TestSpec extends Specification with ScalaCheck {
  "Calling test spec" should {
    "always pass" in prop { (a:Int) => 
      true
    }
    "with a custom generator" in {
      Prop.forAll(smallInteger) { i: Int =>
        true
      }
    }
  }
}
