Scalatest 中 mustBe 的否定是什么

What is the negative of mustBe in Scalatest

我很乐意在 Scalatest 中使用 mustBe。例如

A mustBe (Some(List(1)))

但是我该如何测试 A must not be Some(anything here, done care what it is) 之类的东西?

Negation 可以通过简单地将单词 not 添加到匹配器表达式来断言,例如,

class So1Spec extends FlatSpec with MustMatchers {
  "BeingNegative" should "assert negation" in {
    1 must not be 2
  }
}
