在Propspec和PropertyCheck中使用scalacheck时,如何让ScalaTest正确报告测试结果？

Question

我想使用scalacheck使用基于属性的测试来测试我的scala程序.我写 :

class MyProperties extends PropSpec with PropertyChecks {
    property("My property") {
        val myProperty: org.scalacheck.Prop = new MyProperty
        // some code I need to set myProperty
        myProperty.check
    }
}

但这似乎是错的,因为当我使用ScalaTest运行这个类时,我进入控制台:

Run starting. Expected test count is: 1
MyProperties:

! Falsified after 51 passed tests.
> ARG_0: myGeneratedArgument
- My property
Run completed in 1 second, 623 milliseconds.
Total number of tests run: 1
Suites: completed 1, aborted 0
Tests: succeeded 1, failed 0, canceled 0, ignored 0, pending 0
All tests passed.

所以问题是:我的财产是伪造的,但测试通过了!？!有人看到我的代码出了什么问题吗？

谢谢...

编辑:我试图调用myProperty而不是myProperty.check,但这不是更好,因为这样,生成器似乎被忽略(只启动一个测试而不是一百个).

最终，我找到了一种 Scalatest 考虑的编写测试的方法。我使用了 Checkers Trait 而不是 PropertyChecks：

class MyProperties extends PropSpec with Checkers {
    property("My property") {
        val myProperty: org.scalacheck.Prop = new MyProperty
        // some code I need to set myProperty
        Checkers.check(myProperty)
    }
}

我不确定这是最好的编写方式，但我得到了我想要的。本地：

*** FAILED ***
  GeneratorDrivenPropertyCheckFailedException was thrown during property evaluation.
   (MyProperties.scala:175)
    Falsified after 0 successful property evaluations.
    Location: (MyProperties.scala:175)
    Occurred when passed generated values (
      arg0 = myGeneratedArgument
    )

最后：

Run completed in 4 seconds, 514 milliseconds.
Total number of tests run: 1
Suites: completed 1, aborted 0
Tests: succeeded 0, failed 1, canceled 0, ignored 0, pending 0
*** 1 TESTS FAILED ***

如果有人可以评估这个建议，我会很高兴^^
