ScalaTest 3 中的评估和生产去了哪里？

Question

尝试使用 table 驱动的属性检查以根据以下示例测试无效参数组合 here under Testing invalid argument combinations (bottom of the page, should replaced with must) using ScalaTest 3.0.1，我的 class 扩展 WordSpec with TableDrivenPropertyChecks with MustMatchers:

forAll (invalidCombos) { (n: Int, d: Int) =>
  evaluating {
    new Fraction(n, d)
  } must produce [IllegalArgumentException]
}

但是，IntelliJ IDEA cannot resolve symbol evaluating 和 cannot resolve symbol produce。现在查看 1.8 I found both evaluating and produce, but not in those of 3.0.0 or 3.0.1. The Migrating to 3.0 页面中的 MustMachers 文档没有任何说明。它们去了哪里以及我如何在 ScalaTest 3 中使用它们？

Answer 1

evaluating 关键字已在 ScalaTest 3 中删除，您需要使用 an [Exception] should be thrownBy { ... } 代替 evaluating，例如：

an [IllegalArgumentException] should be thrownBy {
  new Fraction(n, d)
}
