我无法从 Maven 中运行我的 scalachecks。例如下面的小片段

@RunWith(classOf[JUnitRunner])
final class MyTest extends FunSuite with Checkers {
  test("t2") {
    Prop.forAll( (a: String, b: String) => (a+b).startsWith(a) )
  }
}

最终转储以下堆栈：

java.lang.NoSuchMethodError: scala.runtime.IntRef.zero()Lscala/runtime/IntRef;
    at org.scalacheck.Gen$.frequency(Gen.scala)
    at org.scalacheck.Gen$.chooseNum(Gen.scala:455)
    at org.scalacheck.Arbitrary$$anonfun$arbInt$1.apply(Arbitrary.scala:86)

    at org.scalacheck.Prop$.forAll(Prop.scala:726)
    at org.scalacheck.Prop$.forAll(Prop.scala:734)

我敢打赌这只是一件很小的事情要解决，但我找不到使用 junit-runner 在 scalatest 中运行 scala-check 的完整示例。

谢谢并恭祝安康

这对我有用：

import org.junit.runner.RunWith
import org.scalatest.FunSuite
import org.scalatest.prop.GeneratorDrivenPropertyChecks
import org.scalatest.junit.JUnitRunner

@RunWith(classOf[JUnitRunner])
final class MyTest extends FunSuite with GeneratorDrivenPropertyChecks {

  test("t2") {
    forAll { (a: String, b: String) =>
      assert((a + b).startsWith(a))
    }
  }
}
