Scala规范：嵌套语句

Question

是否可以嵌套以下规格测试代码

"ClassX" should {
  "throw an IllegalArgumentException if n < 0" in {
    ClassX(-1) must throwA[IllegalArgumentException]
  }
  "throw an IllegalArgumentException if n > 50" in {
    ClassX(51) must throwA[IllegalArgumentException]
  }
  "throw an IllegalArgumentException if n == 35" in {
    ClassX(35) must throwA[IllegalArgumentException]
  }
}

在另一个声明如下：

"ClassX" should {
  "throw an IllegalArgumentException if" in {
    "n < 0" in {
      ClassX(-1) must throwA[IllegalArgumentException]
    }
    "n > 50" in  {
      ClassX(51) must throwA[IllegalArgumentException]
    }
    "n == 35" in  {
      ClassX(35) must throwA[IllegalArgumentException]
    }
  }
}

因为它更易于阅读和书写

Answer 1

是。有关构建规范规范的所有方法的概述，请参阅http://code.google.com/p/specs/wiki/DeclareSpecifications。

Answer 2

我更喜欢这样的代码：

 "My Component" >> {
   " some general function" can {
     "do stuff that I like" in {
       //…
     }
     "do stuff others like" in {
       //…
     }
   }
 }

但是你可能会注意到有很多方法可以做到。
